[Previous: qmake Reference] [Next: qmake Function Reference]
qmake's fundamental behavior is influenced by variable declarations that define the build process of each project. Some of these declare resources, such as headers and source files, that are common to each platform; others are used to customize the behavior of compilers and linkers on specific platforms.
Platform-specific variables follow the naming pattern of the variables which they extend or modify, but include the name of the relevant platform in their name. For example, QMAKE_LIBS can be used to specify a list of libraries that a project needs to link against, and QMAKE_LIBS_X11 can be used to extend or override this list.
This is only used on the Symbian platform.
Generic bld.inf file content can be specified with BLD_INF_RULES variables. The section of bld.inf file where each rule goes is appended to BLD_INF_RULES with a dot.
For example:
my_exports = \
"foo.h /epoc32/include/mylib/foo.h" \
"bar.h /epoc32/include/mylib/bar.h"
BLD_INF_RULES.prj_exports += my_exports
This will add the specified statements to the prj_exports section of the generated bld.inf file.
It is also possible to add multiple rows in a single block. Each double quoted string will be placed on a new row in the generated bld.inf file.
For example:
myextension = \
"start extension myextension" \
"$${LITERAL_HASH}if defined(WINSCW)" \
"option MYOPTION foo" \
"$${LITERAL_HASH}endif" \
"option MYOPTION bar" \
"end"
BLD_INF_RULES.prj_extensions += myextension
Any rules you define will be added after automatically generated rules in each section.
The CONFIG variable specifies project configuration and compiler options. The values will be recognized internally by qmake and have special meaning. They are as follows.
These CONFIG values control compilation flags:
| Option | Description |
|---|---|
| release | The project is to be built in release mode. This is ignored if debug is also specified. |
| debug | The project is to be built in debug mode. |
| debug_and_release | The project is built in both debug and release modes. This can have some unexpected side effects (see below for more information). |
| build_all | If debug_and_release is specified, the project is built in both debug and release modes by default. |
| ordered | When using the subdirs template, this option specifies that the directories listed should be processed in the order in which they are given. |
| precompile_header | Enables support for the use of precompiled headers in projects. |
| warn_on | The compiler should output as many warnings as possible. This is ignored if warn_off is specified. |
| warn_off | The compiler should output as few warnings as possible. |
Since the debug option overrides the release option when both are defined in the CONFIG variable, it is necessary to use the debug_and_release option if you want to allow both debug and release versions of a project to be built. In such a case, the Makefile that qmake generates includes a rule that builds both versions, and this can be invoked in the following way:
make all
When linking a library, qmake relies on the underlying platform to know what other libraries this library links against. However, if linking statically, qmake will not get this information unless we use the following CONFIG options:
| Option | Description |
|---|---|
| create_prl | This option enables qmake to track these dependencies. When this option is enabled, qmake will create a file ending in .prl which will save meta-information about the library (see Library Dependencies for more info). |
| link_prl | When this is enabled, qmake will process all libraries linked to by the application and find their meta-information(see Library Dependencies for more info). |
Please note that create_prl is required when building a static library, while link_prl is required when using a static library.
On Windows (or if Qt is configured with -debug_and_release, adding the build_all option to the CONFIG variable makes this rule the default when building the project, and installation targets will be created for both debug and release builds.
Additionally, adding debug_and_release to the CONFIG variable will cause both debug and release to be defined in the contents of CONFIG. When the project file is processed, the scopes that test for each value will be processed for both debug and release modes. The build_pass variable will be set for each of these mode, and you can test for this to perform build-specific tasks. For example:
build_pass:CONFIG(debug, debug|release) {
unix: TARGET = $$join(TARGET,,,_debug)
else: TARGET = $$join(TARGET,,,d)
}
As a result, it may be useful to define mode-specific variables, such as QMAKE_LFLAGS_RELEASE, instead of general variables, such as QMAKE_LFLAGS, where possible.
The following options define the application/library type:
| Option | Description |
|---|---|
| qt | The target is a Qt application/library and requires the Qt library and header files. The proper include and library paths for the Qt library will automatically be added to the project. This is defined by default, and can be fine-tuned with the \l{#qt}{QT} variable. |
| thread | The target is a multi-threaded application or library. The proper defines and compiler flags will automatically be added to the project. |
| x11 | The target is a X11 application or library. The proper include paths and libraries will automatically be added to the project. |
| windows | The target is a Win32 window application (app only). The proper include paths, compiler flags and libraries will automatically be added to the project. |
| console | The target is a Win32 console application (app only). The proper include paths, compiler flags and libraries will automatically be added to the project. |
| shared | The target is a shared object/DLL. The proper include paths, compiler flags and libraries will automatically be added to the project. |
| dll | |
| dylib | |
| static | The target is a static library (lib only). The proper compiler flags will automatically be added to the project. |
| staticlib | |
| plugin | The target is a plugin (lib only). This enables dll as well. |
| designer | The target is a plugin for Qt Designer. |
| uic3 | Configures qmake to run uic3 on the content of FORMS3 if defined; otherwise the contents of FORMS will be processed instead. |
| no_lflags_merge | Ensures that the list of libraries stored in the LIBS variable is not reduced to a list of unique values before it is used. |
| resources | Configures qmake to run rcc on the content of RESOURCES if defined. |
These options are used to set the compiler flags:
| Option | Description |
|---|---|
| 3dnow | AMD 3DNow! instruction support is enabled. |
| exceptions | Exception support is enabled. |
| mmx | Intel MMX instruction support is enabled. |
| rtti | RTTI support is enabled. |
| stl | STL support is enabled. |
| sse | SSE support is enabled. |
| sse2 | SSE2 support is enabled. |
These options define specific features on Windows only:
| Option | Description |
|---|---|
| flat | When using the vcapp template this will put all the source files into the source group and the header files into the header group regardless of what directory they reside in. Turning this option off will group the files within the source/header group depending on the directory they reside. This is turned on by default. |
| embed_manifest_dll | Embeds a manifest file in the DLL created as part of a library project. |
| embed_manifest_exe | Embeds a manifest file in the DLL created as part of an application project. |
| incremental | Used to enable or disable incremental linking in Visual C++, depending on whether this feature is enabled or disabled by default. |
See qmake Platform Notes for more information on the options for embedding manifest files.
These options only have an effect on Mac OS X:
| Option | Description |
|---|---|
| ppc | Builds a PowerPC binary. |
| x86 | Builds an i386 compatible binary. |
| app_bundle | Puts the executable into a bundle (this is the default). |
| lib_bundle | Puts the library into a library bundle. |
The build process for bundles is also influenced by the contents of the QMAKE_BUNDLE_DATA variable.
These options only have an effect on the Symbian platform:
| Option | Description |
|---|---|
| stdbinary | Builds an Open C binary (i.e. STDDLL, STDEXE, or STDLIB, depending on the target binary type.) |
| no_icon | Doesn't generate resources needed for displaying an icon for executable in application menu (app only). |
| symbian_test | Places mmp files and extension makefiles under test sections in generated bld.inf instead of their regular sections. Note that this only affects automatically generated bld.inf content; the content added via BLD_INF_RULES variable is not affected. |
| localize_deployment | Makes lupdate tool add fields for application captions and package file names into generated .ts files. Qmake generates properly localized .loc and .pkg files based on available translations. Translation file name bodies must end with underscore and the language code for deployment localization to work. E.g. myapp_en.ts. Note: All languages supported by Qt are not supported by Symbian, so some .ts files may be ignored by qmake. |
These options have an effect on Linux/Unix platforms:
| Option | Description |
|---|---|
| largefile | Includes support for large files. |
| separate_debug_info | Puts debugging information for libraries in separate files. |
The CONFIG variable will also be checked when resolving scopes. You may assign anything to this variable.
For example:
CONFIG += qt console newstuff
...
newstuff {
SOURCES += new.cpp
HEADERS += new.h
}
qmake adds the values of this variable as compiler C preprocessor macros (-D option).
For example:
DEFINES += USE_MY_STUFF QT_DLL
This is only used on Windows when using the app template, and on Symbian when building a shared DLL.
Specifies a .def file to be included in the project. On Symbian a directory may be specified instead, in which case the real files will be located under the standard Symbian directories bwins and eabi.
This variable contains the list of all directories to look in to resolve dependencies. This will be used when crawling through included files.
This is only used on Windows CE and the Symbian platform.
Specifies which additional files will be deployed. Deployment means the transfer of files from the development system to the target device or emulator.
Files can be deployed by either creating a Visual Studio project or using the cetest executable.
For example:
myFiles.sources = path\*.png DEPLOYMENT += myFiles
This will upload all PNG images in path to the same directory your build target will be deployed to.
The default deployment target path for Windows CE is %CSIDL_PROGRAM_FILES%\target, which usually gets expanded to \Program Files\target. For the Symbian platform, the default target is the application private directory on the drive it is installed to.
It is also possible to specify multiple sources to be deployed on target paths. In addition, different variables can be used for deployment to different directories.
For example:
myFiles.sources = path\file1.ext1 path2\file2.ext1 path3\* myFiles.path = \some\path\on\device someother.sources = C:\additional\files\* someother.path = \myFiles\path2 DEPLOYMENT += myFiles someother
Note: In Windows CE all linked Qt libraries will be deployed to the path specified by myFiles.path. On Symbian platform all libraries and executables will always be deployed to the \sys\bin of the installation drive.
Since the Symbian platform build system automatically moves binaries to certain directories under the epoc32 directory, custom plugins, executables or dynamically loadable libraries need special handling. When deploying extra executables or dynamically loadable libraries, the target path must specify \sys\bin. For plugins, the target path must specify the location where the plugin stub will be deployed to (see the How to Create Qt Plugins document for more information about plugins). If the binary cannot be found from the indicated source path, the directory Symbian build process moves the executables to is searched, e.g. \epoc32\release\armv5\urel.
For example:
customplugin.sources = customimageplugin.dll customplugin.sources += c:\myplugins\othercustomimageplugin.dll customplugin.path = imageformats dynamiclibrary.sources = mylib.dll helper.exe dynamiclibrary.path = \sys\bin globalplugin.sources = someglobalimageplugin.dll globalplugin.path = \resource\qt\plugins\imageformats DEPLOYMENT += customplugin dynamiclibrary globalplugin
On the Symbian platform, generic PKG file content can also be specified with this variable. You can use either pkg_prerules or pkg_postrules to pass raw data to PKG file. The strings in pkg_prerules are added before package-body and pkg_postrules after. pkg_prerules is used for defining vendor information, dependencies, custom package headers, and the like, while pkg_postrules is used for custom file deployment and embedded sis directives. The strings defined in pkg_postrules or pkg_prerules are not parsed by qmake, so they should be in a format understood by Symbian package generation tools. Please consult the Symbian platform documentation for correct syntax.
For example, to deploy DLL and add a new dependency:
somelib.sources = somelib.dll
somelib.path = \sys\bin
somelib.pkg_prerules = "(0x12345678), 2, 2, 0, {\"Some Package\"}" \
"(0x87654321), 1, *, * ~ 2, 2, 0, {\"Some Other Package\"}"
justdep.pkg_prerules = "(0xAAAABBBB), 0, 2, 0, {\"My Framework\"}"
DEPLOYMENT += somelib justdep
Please note that pkg_prerules can also replace default statements in pkg file. If no pkg_prerules is defined, qmake makes sure that PKG file syntax is correct and it contains all mandatory statements such as:
If you decide to override any of these statements, you need to pay attention that also other statements stay valid. For example if you override languages statement, you must override also package-header statement and all other statements which are language specific.
On the Symbian platform, three separate PKG files are generated:
pkg_prerules and pkg_postrules given without rules suffix will intelligently apply to each of these files, but rules can also be targeted to only one of above files by appending listed rules suffix to the variable name:
my_note.pkg_postrules.installer = "\"myinstallnote.txt\" - \"\", FILETEXT, TEXTCONTINUE" DEPLOYMENT += my_note
On the Symbian platform, the default_deployment item specifies default platform and package dependencies. Those dependencies can be selectively disabled if alternative dependencies need to be defined - e.g. if a specific device is required to run the application or more languages need to be supported by the package file. The supported default_deployment rules that can be disabled are:
For example:
default_deployment.pkg_prerules -= pkg_platform_dependencies
my_deployment.pkg_prerules = "[0x11223344],0,0,0,{\"SomeSpecificDeviceID\"}"
DEPLOYMENT += my_deployment
On the Symbian platform, a default deployment is generated for all application projects. You can modify the autogenerated default deployment via following DEPLOYMENT variable values:
For example:
DEPLOYMENT -= default_bin_deployment default_resource_deployment default_reg_deployment
This will entirely remove the default application deployment.
On the Symbian platform, you can specify file specific install options with .flags modifier. Please consult the Symbian platform documentation for supported options.
For example:
default_bin_deployment.flags += FILERUN RUNINSTALL dep_note.sources = install_note.txt dep_note.flags = FILETEXT TEXTEXIT DEPLOYMENT += dep_note
This will show a message box that gives user an option to cancel the installation and then automatically runs the application after installation is complete.
Note: Automatically running the applications after install may require signing the package with better than self-signed certificate, depending on the phone model. Additionally, some tools such as Runonphone may not work properly with sis packages that automatically run the application upon install.
On the Symbian platform, the default package name and the default name that appears in application menu is derived from the TARGET variable. Often the default is not optimal for displaying to end user. To set a better display name for these purposes, use DEPLOYMENT.display_name variable:
DEPLOYMENT.display_name = My Qt App
On the Symbian platform, you can use DEPLOYMENT.installer_header variable to generate smart installer wrapper for your application. If you specify just UID of the installer package as the value, then installer package name and version will be autogenerated:
DEPLOYMENT.installer_header = 0x12345678
If autogenerated values are not suitable, you can also specify the sis header yourself using this variable:
DEPLOYMENT.installer_header = "$${LITERAL_HASH}{\"My Application Installer\"},(0x12345678),1,0,0"
This is only used on Windows CE and the Symbian platform.
This variable specifies the Qt plugins that will be deployed. All plugins available in Qt can be explicitly deployed to the device. See Static Plugins for a complete list.
Note: In Windows CE, No plugins will be deployed automatically. If the application depends on plugins, these plugins have to be specified manually.
Note: On the Symbian platform, all plugins supported by this variable will be deployed by default with Qt libraries, so generally using this variable is not needed.
For example:
DEPLOYMENT_PLUGIN += qjpeg
This will upload the jpeg imageformat plugin to the plugins directory on the Windows CE device.
Specifies where to put the target file.
For example:
DESTDIR = ../../lib
This variable is set internally by qmake, which is basically the DESTDIR variable with the TARGET variable appened at the end. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
Specifies where to copy the target dll.
This variable contains a list of files to be included in the dist target. This feature is supported by UnixMake specs only.
For example:
DISTFILES += ../program.txt
This variable is set internally by qmake, which specifies where the dsp template file for basing generated dsp files is stored. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable specifies the UI files (see Qt Designer) to be processed through uic before compiling. All dependencies, headers and source files required to build these UI files will automatically be added to the project.
For example:
FORMS = mydialog.ui \
mywidget.ui \
myconfig.ui
If FORMS3 is defined in your project, then this variable must contain forms for uic, and not uic3. If CONFIG contains uic3, and FORMS3 is not defined, the this variable must contain only uic3 type forms.
This variable specifies the old style UI files to be processed through uic3 before compiling, when CONFIG contains uic3. All dependencies, headers and source files required to build these UI files will automatically be added to the project.
For example:
FORMS3 = my_uic3_dialog.ui \
my_uic3_widget.ui \
my_uic3_config.ui
Specifies the GUID that is set inside a .vcproj file. The GUID is usually randomly determined. However, should you require a fixed GUID, it can be set using this variable.
This variable is specific to .vcproj files only; it is ignored otherwise.
Defines the header files for the project.
qmake will generate dependency information (unless -nodepend is specified on the command line) for the specified headers. qmake will also automatically detect if moc is required by the classes in these headers, and add the appropriate dependencies and files to the project for generating and linking the moc files.
For example:
HEADERS = myclass.h \
login.h \
mainwindow.h
See also SOURCES.
This variable is used only in MAC and the Symbian platform to set the application icon. Please see the application icon documentation for more information.
This variable specifies the #include directories which should be searched when compiling the project.
For example:
INCLUDEPATH = c:/msdev/include d:/stl/include
To specify a path containing spaces, quote the path using the technique mentioned in the qmake Project Files document. For example, paths with spaces can be specified on Windows and Unix platforms by using the quote() function in the following way:
win32:INCLUDEPATH += $$quote(C:/mylibs/extra headers) unix:INCLUDEPATH += $$quote(/home/user/extra headers)
This variable contains a list of resources that will be installed when make install or a similar installation procedure is executed. Each item in the list is typically defined with attributes that provide information about where it will be installed.
For example, the following target.path definition describes where the build target will be installed, and the INSTALLS assignment adds the build target to the list of existing resources to be installed:
target.path += $$[QT_INSTALL_PLUGINS]/imageformats INSTALLS += target
Note that qmake will skip files that are executable. If you need to install executable files, you can unset the files' executable flags.
This variable contains a list of lex implementation files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the names of intermediate lex object files.The value of this variable is typically handled by qmake and rarely needs to be modified.
This variable contains a list of lex source files. All dependencies, headers and source files will automatically be added to the project for building these lex files.
For example:
LEXSOURCES = lexer.l
This variable contains a list of libraries to be linked into the project. You can use the Unix -l (library) and -L (library path) flags and qmake will do the correct thing with these libraries on Windows and the Symbian platform (namely this means passing the full path of the library to the linker). The only limitation to this is the library must exist, for qmake to find which directory a -l lib lives in.
For example:
unix:LIBS += -L/usr/local/lib -lmath win32:LIBS += c:/mylibs/math.lib
To specify a path containing spaces, quote the path using the technique mentioned in the qmake Project Files document. For example, paths with spaces can be specified on Windows and Unix platforms by using the quote() function in the following way:
win32:LIBS += $$quote(C:/mylibs/extra libs/extra.lib) unix:LIBS += $$quote(-L/home/user/extra libs) -lextra
Note: On Windows, specifying libraries with the -l option, as in the above example, will cause the library with the highest version number to be used; for example, libmath2.lib could potentially be used instead of libmathlib. To avoid this ambiguity, we recommend that you explicitly specify the library to be used by including the .lib file name suffix.
Note: On the Symbian platform, the build system makes a distinction between shared and static libraries. In most cases, qmake will figure out which library you are refering to, but in some cases you may have to specify it explicitly to get the expected behavior. This typically happens if you are building a library and using it in the same project. To specify that the library is either shared or static, add a ".dll" or ".lib" suffix, respectively, to the library name.
By default, the list of libraries stored in LIBS is reduced to a list of unique names before it is used. To change this behavior, add the no_lflags_merge option to the CONFIG variable:
CONFIG += no_lflags_merge
This variable is used whenever a literal hash character (#) is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application.
For example:
# To include a literal hash character, use the $$LITERAL_HASH variable: urlPieces = http://qt.nokia.com/doc/4.0/qtextdocument.html pageCount message($$join(urlPieces, $$LITERAL_HASH))
By using LITERAL_HASH in this way, the # character can be used to construct a URL for the message() function to print to the console.
This variable specifies the name of the Makefile which qmake should use when outputting the dependency information for building a project. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
Note: On the Symbian platform, this variable is ignored.
This variable contains the name of the Makefile generator to use when generating a Makefile. The value of this variable is typically handled internally by qmake and rarely needs to be modified.
This is only used on the Symbian platform.
Generic MMP file content can be specified with this variable.
For example:
MMP_RULES += "DEFFILE hello.def"
This will add the specified statement to the end of the generated MMP file.
It is also possible to add multiple rows in a single block. Each double quoted string will be placed on a new row in the generated MMP file.
For example:
myBlock = \ "START RESOURCE foo.rss" \ "TARGET bar" \ "TARGETPATH private\10001234" \ "HEADER" \ "LANG 01" \ "UID 0x10002345 0x10003456" \ "END" MMP_RULES += myBlock
If you need to include a hash (#) character inside the MMP_RULES statement, it can be done with the variable LITERAL_HASH as follows:
myIfdefBlock = \
"$${LITERAL_HASH}ifdef WINSCW" \
"DEFFILE hello_winscw.def" \
"$${LITERAL_HASH}endif"
MMP_RULES += myIfdefBlock
There is also a convenience function for adding conditional rules called addMMPRules. Suppose you need certain functionality to require different library depending on architecture. This can be specified with addMMPRules as follows:
# Set conditional libraries LIB.MARM = "LIBRARY myarm.lib" LIB.WINSCW = "LIBRARY mywinscw.lib" LIB.default = "LIBRARY mydefault.lib" # Add the conditional MMP rules MYCONDITIONS = MARM WINSCW MYVARIABLES = LIB addMMPRules(MYCONDITIONS, MYVARIABLES)
Note: You should not use this variable to add MMP statements that are explicitly supported by their own variables, such as TARGET.EPOCSTACKSIZE. Doing so could result in duplicate statements in the MMP file.
This variable specifies the directory where all intermediate moc files should be placed.
For example:
unix:MOC_DIR = ../myproject/tmp win32:MOC_DIR = c:/myproject/tmp
This variable is generated from the SOURCES variable. The extension of each source file will have been replaced by .o (Unix) or .obj (Win32). The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable specifies the directory where all intermediate objects should be placed.
For example:
unix:OBJECTS_DIR = ../myproject/tmp win32:OBJECTS_DIR = c:/myproject/tmp
This variable is set by qmake if files can be found that contain the Q_OBJECT macro. OBJMOC contains the name of all intermediate moc object files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
All libraries that the target depends on can be listed in this variable. Some backends do not support this, these include MSVC Dsp, and ProjectBuilder .pbproj files. Generally this is supported internally by these build tools, this is useful for explicitly listing dependant static libraries.
This list will go after all builtin (and $$PRE_TARGETDEPS) dependencies.
All libraries that the target depends on can be listed in this variable. Some backends do not support this, these include MSVC Dsp, and ProjectBuilder .pbproj files. Generally this is supported internally by these build tools, this is useful for explicitly listing dependant static libraries.
This list will go before all builtin dependencies.
This variable indicates the header file for creating a precompiled header file, to increase the compilation speed of a project. Precompiled headers are currently only supported on some platforms (Windows - all MSVC project types, Mac OS X - Xcode, Makefile, Unix - gcc 3.3 and up).
On other platforms, this variable has different meaning, as noted below.
This variable contains a list of header files that require some sort of pre-compilation step (such as with moc). The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the full path leading to the directory where the qmake project file (project.pro) is located.
This variable contains the full path leading to the directory where qmake places the generated Makefile.
This variable contains the name of the qmake program itself and is placed in generated Makefiles. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the name of the qmake configuration to use when generating Makefiles. The value of this variable is typically handled by qmake and rarely needs to be modified.
Use the QMAKESPEC environment variable to override the qmake configuration. Note that, due to the way qmake reads project files, setting the QMAKESPEC environment variable from within a project file will have no effect.
This variable is empty unless the app TEMPLATE is specified. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified. Use the following instead:
app {
# Conditional code for 'app' template here
}
This variable is empty unless the app or dll TEMPLATE is specified. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This is used on Unix platforms only.
This variable contains the command for invoking the program which creates, modifies and extracts archives. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable is used to hold the data that will be installed with a library bundle, and is often used to specify a collection of header files.
For example, the following lines add path/to/header_one.h and path/to/header_two.h to a group containing information about the headers supplied with the framework:
FRAMEWORK_HEADERS.version = Versions FRAMEWORK_HEADERS.files = path/to/header_one.h path/to/header_two.h FRAMEWORK_HEADERS.path = Headers QMAKE_BUNDLE_DATA += FRAMEWORK_HEADERS
The last line adds the information about the headers to the collection of resources that will be installed with the library bundle.
Library bundles are created when the lib_bundle option is added to the CONFIG variable.
See qmake Platform Notes for more information about creating library bundles.
This is used on Mac OS X only.
This variable defines the extension to be used for library bundles. This allows frameworks to be created with custom extensions instead of the standard .framework directory name extension.
For example, the following definition will result in a framework with the .myframework extension:
QMAKE_BUNDLE_EXTENSION = .myframework
This is used on Mac OS X only.
This variable specifies the C compiler that will be used when building projects containing C source code. Only the file name of the compiler executable needs to be specified as long as it is on a path contained in the PATH variable when the Makefile is processed.
This variable contains the flags for the C compiler in debug mode. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the compiler flags for creating a multi-threaded application or when the version of Qt that you link against is a multi-threaded statically linked library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the compiler flags for creating a debuggable multi-threaded application or when the version of Qt that you link against is a debuggable multi-threaded statically linked library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This is used on Windows only.
This variable contains the compiler flags for creating a multi-threaded dll or when the version of Qt that you link against is a multi-threaded dll. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This is used on Windows only.
This variable contains the compiler flags for creating a debuggable multi-threaded dll or when the version of Qt that you link against is a debuggable multi-threaded statically linked library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the compiler flags for creating a non-debuggable application. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This is used on Unix platforms only.
This variable contains the compiler flags for creating a shared library. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains the compiler flags for creating a multi-threaded application. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable is not empty if the warn_off CONFIG option is specified. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable is not empty if the warn_on CONFIG option is specified. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This variable contains any files which are not generated files (such as moc and uic generated files) and object files that should be removed when using "make clean".

The values stored in the QT variable control which of the Qt modules are used by your project.
The table below shows the options that can be used with the QT variable and the features that are associated with each of them:
| Option | Features |
|---|---|
| core (included by default) | QtCore module |
| gui (included by default) | QtGui module |
| network | QtNetwork module |
| opengl | QtOpenGL module |
| phonon | Phonon Multimedia Framework |
| sql | QtSql module |
| svg | QtSvg module |
| xml | QtXml module |
| webkit | WebKit integration |
| qt3support | Qt3Support module |
By default, QT contains both core and gui, ensuring that standard GUI applications can be built without further configuration.
If you want to build a project without the QtGui module, you need to exclude the gui value with the "-=" operator; the following line will result in a minimal Qt project being built:
QT -= gui # Only the core module is used.
Note that adding the opengl option to the QT variable automatically causes the equivalent option to be added to the CONFIG variable. Therefore, for Qt applications, it is not necessary to add the opengl option to both CONFIG and QT.
This variable contains a list of names of static plugins that are to be compiled with an application so that they are available as built-in resources.
This variable contains the current version of Qt.

This is a special variable processed by qmake. If the contents of this variable do not appear in CONFIG by the time this variable is assigned, then a minimal Makefile will be generated that states what dependencies (the values assigned to REQUIRES) are missing.
This is mainly used in Qt's build system for building the examples.
This variable contains the name of the resource collection file (qrc) for the application. Further information about the resource collection file can be found at The Qt Resource System.
This variable contains the name of the resource file for the application. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.
This is only used on the Symbian platform.
Generic RSS file content can be specified with this variable. The syntax is similar to MMP_RULES and BLD_INF_RULES.
For example:
RSS_RULES += "hidden = KAppIsHidden;"
This will add the specified statement to the end of the APP_REGISTRATION_INFO resource struct in the generated registration resource file. As an impact of this statement, the application will not be visible in application shell.
It is also possible to add multiple rows in a single block. Each double quoted string will be placed on a new row in the registration resource file.
For example:
myrssrules = \
"hidden = KAppIsHidden;" \
"launch = KAppLaunchInBackground;" \
RSS_RULES += myrssrules
This example will install the application to MyFolder in the Symbian platform application shell. In addition it will make the application to be launched in background.
For detailed list of possible APP_REGISTRATION_INFO statements, please refer to the Symbian platform help.
Note: You should not use RSS_RULES variable to set the following RSS statements: app_file, localisable_resource_file, and localisable_resource_id.
These statements are internally handled by qmake.
There is a number of special modifiers you can attach to RSS_RULES to specify where in the application registration file the rule will be written:
| Modifier | Location of the rule |
|---|---|
| <no modifier> | Inside APP_REGISTRATION_INFO resource struct. |
| .header | Before APP_REGISTRATION_INFO resource struct. |
| .footer | After APP_REGISTRATION_INFO resource struct. |
| .service_list | Inside a SERVICE_INFO item in the service_list of APP_REGISTRATION_INFO |
| .file_ownership_list | Inside a FILE_OWNERSHIP_INFO item in the file_ownership_list of APP_REGISTRATION_INFO |
| .datatype_list | Inside a DATATYPE item in the datatype_list of APP_REGISTRATION_INFO |
For example:
RSS_RULES.service_list += "uid = 0x12345678; datatype_list = \{\}; opaque_data = r_my_icon;"
RSS_RULES.footer +="RESOURCE CAPTION_AND_ICON_INFO r_my_icon \{ icon_file =\"$$PWD/my_icon.svg\"; \}"
This example will define service information for a fictional service that requires an icon to be supplied via the opaque_data of the service information.

This variable, when used with the subdirs template contains the names of all subdirectories or project files that contain parts of the project that need be built. Each subdirectory specified using this variable must contain its own project file.
For example:
SUBDIRS = kernel \
tools
It is essential that the project file in each subdirectory has the same name as the subdirectory itself, so that qmake can find it. For example, if the subdirectory is called myapp then the project file in that directory should be called myapp.pro.
If you need to ensure that the subdirectories are built in the order in which they are specified, update the CONFIG variable to include the ordered option:
CONFIG += ordered
It is possible to modify this default behavior of SUBDIRS by giving additional modifiers to SUBDIRS elements. Supported modifiers are:
| Modifier | Effect |
|---|---|
| .subdir | Use the specified subdirectory instead of SUBDIRS value. |
| .file | Specify the subproject pro file explicitly. Cannot be used in conjunction with .subdir modifier. |
| .condition | Specifies a bld.inf define that must be true for subproject to be built. Available only on Symbian platform. |
| .depends | This subproject depends on specified subproject. Available only on platforms that use makefiles. |
| .makefile | The makefile of subproject. Available only on platforms that use makefiles. |
| .target | Base string used for makefile targets related to this subproject. Available only on platforms that use makefiles. |
For example, define two subdirectories, both of which reside in a different directory than the SUBDIRS value, and one of the subdirectories must be built before the other:
SUBDIRS += my_executable my_library my_executable.subdir = app my_executable.depends = my_library my_library.subdir = lib
For example, define a subdirectory that is only build for emulator builds in Qt for Symbian:
symbian {
SUBDIRS += emulator_dll
emulator_dll.condition = WINSCW
}
This is only used on the Symbian platform.
Contains the version number of the underlying Symbian SDK; e.g. "9.2" or "Symbian3".
This specifies the name of the target file.
For example:
TEMPLATE = app TARGET = myapp SOURCES = main.cpp
The project file above would produce an executable named myapp on unix and 'myapp.exe' on windows.
This is only used on the Symbian platform.
Specifies which platform capabilities the application should have. These include the following basic capabilities, but others are also available for signed applications.
| Capability | Description |

For more information, and a comprehensive list of capabilities, please refer to the Symbian SDK documentation or the Symbian Capabilities page of the Forum Nokia Wiki.
This is only used on the Symbian platform.
Specifies whether static data should be allowed in the application. Symbian disallows this by default in order to save memory. To use it, set this to 1.
This is only used on the Symbian platform.
Specifies the minimum and maximum heap size of the application. The program will refuse to run if the minimum size is not available when it starts. For example:

| vclib | Windows only Creates a library project for Visual Studio. (See qmake Platform Notes for more information.) |
For example:
TEMPLATE = lib SOURCES = main.cpp TARGET = mylib
The template can be overridden by specifying a new template type with the -t command line option. This overrides the template type after the .pro file has been processed. With .pro files that use the template type to determine how the project is built, it is necessary to declare TEMPLATE on the command line rather than use the -t option.
