qmake Variable 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.

BLD_INF_RULES

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:

 BLD_INF_RULES.prj_exports += \
     "$${LITERAL_HASH}include <platform_paths.hrh>" \
     "rom/my.iby  APP_LAYER_PUBLIC_EXPORT_PATH(my.iby)" \
     "inc/myheader.h mycomp/myheader.h" \
     ":zip my_api.zip my_api"

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.

CONFIG

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:

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:

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:

These options are used to set the compiler flags:

These options define specific features on Windows only:

See qmake Platform Notes for more information on the options for embedding manifest files.

These options only have an effect on Mac OS X:

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:

These options have an effect on Linux/Unix platforms:

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
 }

DEFINES

qmake adds the values of this variable as compiler C preprocessor macros (-D option).

For example:

 DEFINES += USE_MY_STUFF QT_DLL

DEF_FILE

This is only used on Windows when using the app template.

Specifies a .def file to be included in the project.

DEPENDPATH

This variable contains the list of all directories to look in to resolve dependencies. This will be used when crawling through included files.

DEPLOYMENT

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. 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:

• languages, for example
  &EN,FR
• package-header, for example
  #{"MyApp-EN", "MyApp-FR"}, (0x1000001F), 1, 2, 3, TYPE=SA
• localized and unique vendor, for example
  %{"Vendor-EN", ..., "Vendor-FR"} :"Unique vendor name"

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, the default_deployment item specifies default platform dependencies. It can be overwritten if a more restrictive set is needed - e.g. if a specific device is required to run the application.

For example:

 default_deployment.pkg_prerules = "[0x11223344],0,0,0,{\"SomeSpecificDeviceID\"}"

DEPLOYMENT_PLUGIN

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.

DESTDIR

Specifies where to put the target file.

For example:

 DESTDIR = ../../lib

DESTDIR_TARGET

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.

DLLDESTDIR

Specifies where to copy the target dll.

DISTFILES

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

DSP_TEMPLATE

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.

FORMS

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.

FORMS3

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

GUID

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.

HEADERS

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.

ICON

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.

INCLUDEPATH

This variable specifies the #include directories which should be searched when compiling the project. Use ';' or a space as the directory separator.

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)

INSTALLS

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

LEXIMPLS

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.

LEXOBJECTS

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.

LEXSOURCES

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

LIBS

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

LITERAL_HASH

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.

MAKEFILE

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.

MAKEFILE_GENERATOR

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.

MMP_RULES

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

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.

MOC_DIR

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

OBJECTS

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.

OBJECTS_DIR

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

OBJMOC

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.

POST_TARGETDEPS

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.

PRE_TARGETDEPS

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.

PRECOMPILED_HEADER

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.

OUT_PWD

This variable contains the full path leading to the directory where qmake places the generated Makefile.

QMAKE

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.

QMAKESPEC

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.

QMAKE_APP_FLAG

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
 }

QMAKE_APP_OR_DLL

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.

QMAKE_AR_CMD

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.

QMAKE_BUNDLE_DATA

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.

QMAKE_BUNDLE_EXTENSION

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.

QT

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:

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.

REQUIRES

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.

RESOURCES

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.

RES_FILE

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.

RSS_RULES

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 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 RSS 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 localisable_resource_id

These statements are internally handled by qmake.

This variable is set by qmake if files can be found that contain the Q_OBJECT macro. SRCMOC contains the name of all the generated moc files. The value of this variable is typically handled by qmake or qmake.conf and rarely needs to be modified.

SUBDIRS

This variable, when used with the subdirs template contains the names of all subdirectories that contain parts of the project that need be built. Each subdirectory 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

TARGET
