<!-- $$$qmake-variable-reference.html-description -->
<div class="descr"> <a name="details"></a>
<p>The fundamental behavior of qmake 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.</p>
<p>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, <code>QMAKE_LIBS</code> can be used to specify a list of libraries that a project needs to link against, and <code>QMAKE_LIBS_X11</code> can be used to extend or override this list.</p>
<a name="config"></a><a name="config"></a>
<h2 id="config">CONFIG</h2>
<p>Specifies project configuration and compiler options. The values are recognized internally by qmake and have special meaning.</p>
<p>The following <code>CONFIG</code> values control compilation flags:</p>
<div class="table"><table class="generic">
<thead><tr class="qt-style"><th >Option</th><th >Description</th></tr></thead>
<tr valign="top" class="odd"><td >release</td><td >The project is to be built in release mode. If <code>debug</code> is also specified, the last one takes effect.</td></tr>
<tr valign="top" class="even"><td >debug</td><td >The project is to be built in debug mode.</td></tr>
<tr valign="top" class="odd"><td >debug_and_release</td><td >The project is prepared to be built in <i>both</i> debug and release modes.</td></tr>
<tr valign="top" class="even"><td >debug_and_release_target</td><td >This option is set by default. If <code>debug_and_release</code> is also set, the debug and release builds end up in separate debug and release directories.</td></tr>
<tr valign="top" class="odd"><td >build_all</td><td >If <code>debug_and_release</code> is specified, the project is built in both debug and release modes by default.</td></tr>
<tr valign="top" class="even"><td >autogen_precompile_source</td><td >Automatically generates a <code>.cpp</code> file that includes the precompiled header file specified in the .pro file.</td></tr>
<tr valign="top" class="odd"><td >ordered</td><td >When using the <code>subdirs</code> template, this option specifies that the directories listed should be processed in the order in which they are given.</td></tr>
<tr valign="top" class="even"><td >precompile_header</td><td >Enables support for the use of <a href="qmake-precompiledheaders.html">precompiled headers</a> in projects.</td></tr>
<tr valign="top" class="odd"><td >warn_on</td><td >The compiler should output as many warnings as possible. If <code>warn_off</code> is also specified, the last one takes effect.</td></tr>
<tr valign="top" class="even"><td >warn_off</td><td >The compiler should output as few warnings as possible.</td></tr>
<tr valign="top" class="odd"><td >exceptions</td><td >Exception support is enabled. Set by default.</td></tr>
<tr valign="top" class="even"><td >exceptions_off</td><td >Exception support is disabled.</td></tr>
<tr valign="top" class="odd"><td >rtti</td><td >RTTI support is enabled. By default, the compiler default is used.</td></tr>
<tr valign="top" class="even"><td >rtti_off</td><td >RTTI support is disabled. By default, the compiler default is used.</td></tr>
<tr valign="top" class="odd"><td >stl</td><td >STL support is enabled. By default, the compiler default is used.</td></tr>
<tr valign="top" class="even"><td >stl_off</td><td >STL support is disabled. By default, the compiler default is used.</td></tr>
<tr valign="top" class="odd"><td >thread</td><td >Thread support is enabled. This is enabled when CONFIG includes <code>qt</code>, which is the default.</td></tr>
<tr valign="top" class="even"><td >c++11</td><td >C++11 support is enabled. This option has no effect if the compiler does not support C++11. By default, support is disabled.</td></tr>
<tr valign="top" class="odd"><td >c++14</td><td >C++14 support is enabled. This option has no effect if the compiler does not support C++14. By default, support is disabled.</td></tr>
<tr valign="top" class="even"><td >depend_includepath</td><td >Appending the value of INCLUDEPATH to DEPENDPATH is enabled. Set by default.</td></tr>
</table></div>
<p>When you use the <code>debug_and_release</code> option (which is the default under Windows), the project will be processed three times: one time to produce a "meta" Makefile, and two more times to produce a Makefile.Debug and a Makefile.Release.</p>
<p>During the latter passes, <code>build_pass</code> and the respective <code>debug</code> or <code>release</code> option is appended to <code>CONFIG</code>. This makes it possible to perform build-specific tasks. For example:</p>
<pre class="cpp">
build_pass:CONFIG(debug, debug|release) {
unix: TARGET = $$join(TARGET,,,_debug)
else: TARGET = $$join(TARGET,,,d)
}
</pre>
<p>As an alternative to manually writing build type conditionals, some variables offer build-specific variants, for example <a href="qmake-variable-reference.html#qmake-lflags-release">QMAKE_LFLAGS_RELEASE</a> in addition to the general <a href="qmake-variable-reference.html#qmake-lflags">QMAKE_LFLAGS</a>. These should be used when available.</p>
<p>The meta Makefile makes the sub-builds invokable via the <code>debug</code> and <code>release</code> targets, and a combined build via the <code>all</code> target. When the <code>build_all</code> <code>CONFIG</code> option is used, the combined build is the default. Otherwise, the last specified <code>CONFIG</code> option from the set (<code>debug</code>, <code>release</code>) determines the default. In this case, you can explicitly invoke the <code>all</code> target to build both configurations at once:</p>
<pre class="cpp">
make all
</pre>
<p><b>Note: </b>The details are slightly different when producing Visual Studio and Xcode projects.</p><p>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 <code>CONFIG</code> options:</p>
<div class="table"><table class="generic">
<thead><tr class="qt-style"><th >Option</th><th >Description</th></tr></thead>
<tr valign="top" class="odd"><td >create_prl</td><td >This option enables qmake to track these dependencies. When this option is enabled, qmake will create a file with the extension <code>.prl</code> which will save meta-information about the library (see <a href="qmake-advanced-usage.html#libdepend">Library Dependencies</a> for more info).</td></tr>
<tr valign="top" class="even"><td >link_prl</td><td >When this option is enabled, qmake will process all libraries linked to by the application and find their meta-information (see <a href="qmake-advanced-usage.html#libdepend">Library Dependencies</a> for more info).</td></tr>
</table></div>
<p><b>Note: </b>The <code>create_prl</code> option is required when <i>building</i> a static library, while <code>link_prl</code> is required when <i>using</i> a static library.</p><p>The following options define the application or library type:</p>

<p>For example:</p>
<pre class="cpp">
CONFIG += console newstuff
...
newstuff {
SOURCES += new.cpp
HEADERS += new.h
}
</pre>
<a name="defines"></a><a name="defines"></a>
<h2 id="defines">DEFINES</h2>
<p>qmake adds the values of this variable as compiler C preprocessor macros (-D option).</p>
<p>For example:</p>
<pre class="cpp">

<a name="headers"></a><a name="headers"></a>
<h2 id="headers">HEADERS</h2>
<p>Defines the header files for the project.</p>
<p>qmake automatically detects whether moc is required by the classes in the headers, and adds the appropriate dependencies and files to the project for generating and linking the moc files.</p>
<p>For example:</p>
<pre class="cpp">
HEADERS = myclass.h \
login.h \
mainwindow.h
</pre>

<a name="includepath"></a><a name="includepath"></a>
<h2 id="includepath">INCLUDEPATH</h2>
<p>Specifies the #include directories which should be searched when compiling the project.</p>
<p>For example:</p>
<pre class="cpp">
INCLUDEPATH = c:/msdev/include d:/stl/include
</pre>
<p>To specify a path containing spaces, quote the path using the technique described in <a href="qmake-project-files.html#whitespace">Whitespace</a>.</p>
<pre class="cpp">
win32:INCLUDEPATH += "C:/mylibs/extra headers"

</pre>
<a name="installs"></a><a name="installs"></a>
<h2 id="installs">INSTALLS</h2>
<p>Specifies a list of resources that will be installed when <code>make install</code> 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.</p>
<p>For example, the following <code>target.path</code> definition describes where the build target will be installed, and the <code>INSTALLS</code> assignment adds the build target to the list of existing resources to be installed:</p>
<pre class="cpp">
target.path += $$[QT_INSTALL_PLUGINS]/imageformats
INSTALLS += target
</pre>
<p>For more information, see <a href="qmake-advanced-usage.html#installing-files">Installing Files</a>.</p>

<p>For example:</p>
<pre class="cpp">
LEXSOURCES = lexer.l
</pre>
<a name="libs"></a><a name="libs"></a>
<h2 id="libs">LIBS</h2>
<p>Specifies a list of libraries to be linked into the project. If you use the Unix <code>-l</code> (library) and -L (library path) flags, qmake handles the libraries correctly on Windows (that is, passes the full path of the library to the linker). The library must exist for qmake to find the directory where a <code>-l</code> lib is located.</p>
<p>For example:</p>
<pre class="cpp">
unix:LIBS += -L/usr/local/lib -lmath
win32:LIBS += c:/mylibs/math.lib
</pre>
<p>To specify a path containing spaces, quote the path using the technique described in <a href="qmake-project-files.html#whitespace">Whitespace</a>.</p>
<pre class="cpp">
win32:LIBS += "C:/mylibs/extra libs/extra.lib"
unix:LIBS += "-L/home/user/extra libs" -lextra
</pre>
<p>By default, the list of libraries stored in <code>LIBS</code> is reduced to a list of unique names before it is used. To change this behavior, add the <code>no_lflags_merge</code> option to the <a href="qmake-variable-reference.html#config">CONFIG</a> variable:</p>
<pre class="cpp">
CONFIG += no_lflags_merge
</pre>
<a name="literal-hash"></a><a name="literal-hash"></a>
<h2 id="literal-hash">LITERAL_HASH</h2>
<p>This variable is used whenever a literal hash character (<code>#</code>) is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application.</p>
<p>For example:</p>
<pre class="cpp">
# To include a literal hash character, use the $$LITERAL_HASH variable:
urlPieces = http://doc.qt.io/qt-5/qtextdocument.html pageCount
message($$join(urlPieces, $$LITERAL_HASH))
</pre>
<p>By using <code>LITERAL_HASH</code> in this way, the <code>#</code> character can be used to construct a URL for the <code>message()</code> function to print to the console.</p>
<a name="makefile"></a><a name="makefile"></a>
<h2 id="makefile">MAKEFILE</h2>
<p>Specifies the name of the generated Makefile. The value of this variable is typically handled by qmake or <a href="qmake-variable-reference.html#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>

<a name="moc-dir"></a><a name="moc-dir"></a>
<h2 id="moc-dir">MOC_DIR</h2>
<p>Specifies the directory where all intermediate moc files should be placed.</p>
<p>For example:</p>
<pre class="cpp">
unix:MOC_DIR = ../myproject/tmp
win32:MOC_DIR = c:/myproject/tmp
</pre>
<a name="objects"></a><a name="objects"></a>
<h2 id="objects">OBJECTS</h2>
<p>This variable is automatically populated from the <a href="qmake-variable-reference.html#sources">SOURCES</a> variable. The extension of each source file is replaced by .o (Unix) or .obj (Win32). You can add objects to the list.</p>
<a name="objects-dir"></a><a name="objects-dir"></a>
<h2 id="objects-dir">OBJECTS_DIR</h2>
<p>Specifies the directory where all intermediate objects should be placed.</p>
<p>For example:</p>
<pre class="cpp">

<a name="res-file"></a>
<h2 id="res-file">RES_FILE</h2>
<p>Specifies the name of the compiled Windows resource file for the target. The value of this variable is typically handled by qmake or <a href="qmake-variable-reference.html#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="sources"></a><a name="sources"></a>
<h2 id="sources">SOURCES</h2>
<p>Specifies the names of all source files in the project.</p>
<p>For example:</p>
<pre class="cpp">
SOURCES = myclass.cpp \

</pre>
<p>See also <a href="qmake-variable-reference.html#headers">HEADERS</a>.</p>
<a name="subdirs"></a><a name="subdirs"></a>
<h2 id="subdirs">SUBDIRS</h2>
<p>This variable, when used with the <code>subdirs</code> <a href="qmake-variable-reference.html#template">template</a> specifies the names of all subdirectories or project files that contain parts of the project that need to be built. Each subdirectory specified using this variable must contain its own project file.</p>
<p>It is recommended that the project file in each subdirectory has the same base name as the subdirectory itself, because that makes it possible to omit the file name. For example, if the subdirectory is called <code>myapp</code>, the project file in that directory should be called <code>myapp.pro</code>.</p>
<p>Alternatively, you can specify a relative path to a .pro file in any directory. It is strongly recommended that you specify only paths in the current project's parent directory or its subdirectories.</p>
<p>For example:</p>
<pre class="cpp">
SUBDIRS = kernel \
tools \
myapp
</pre>
<p>If you need to ensure that the subdirectories are built in the order in which they are specified, update the <a href="qmake-variable-reference.html#config">CONFIG</a> variable to include the <code>ordered</code> option:</p>
<pre class="cpp">
CONFIG += ordered
</pre>
<p>It is possible to modify this default behavior of <code>SUBDIRS</code> by giving additional modifiers to <code>SUBDIRS</code> elements. Supported modifiers are:</p>
<div class="table"><table class="generic">
<thead><tr class="qt-style"><th >Modifier</th><th >Effect</th></tr></thead>
<tr valign="top" class="odd"><td >.subdir</td><td >Use the specified subdirectory instead of <code>SUBDIRS</code> value.</td></tr>
<tr valign="top" class="even"><td >.file</td><td >Specify the subproject <code>pro</code> file explicitly. Cannot be used in conjunction with <code>.subdir</code> modifier.</td></tr>
<tr valign="top" class="odd"><td >.depends</td><td >This subproject depends on specified subproject.</td></tr>
<tr valign="top" class="even"><td >.makefile</td><td >The makefile of subproject. Available only on platforms that use makefiles.</td></tr>
<tr valign="top" class="odd"><td >.target</td><td >Base string used for makefile targets related to this subproject. Available only on platforms that use makefiles.</td></tr>
</table></div>
<p>For example, define two subdirectories, both of which reside in a different directory than the <code>SUBDIRS</code> value, and one of the subdirectories must be built before the other:</p>
<pre class="cpp">
SUBDIRS += my_executable my_library
my_executable.subdir = app
my_executable.depends = my_library
my_library.subdir = lib
</pre>
<a name="target"></a><a name="target"></a>
<h2 id="target">TARGET</h2>
<p>Specifies the name of the target file. Contains the base name of the project file by default.</p>
<p>For example:</p>
<pre class="cpp">
TEMPLATE = app
TARGET = myapp
SOURCES = main.cpp
</pre>
<p>The project file above would produce an executable named <code>myapp</code> on unix and <code>myapp.exe</code> on Windows.</p>
<a name="target-ext"></a>
<h2 id="target-ext">TARGET_EXT</h2>
<p>Specifies the extension of <code>TARGET</code>. The value of this variable is typically handled by qmake or <a href="qmake-variable-reference.html#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="target-x"></a>
<h2 id="target-x">TARGET_x</h2>
<p>Specifies the extension of <code>TARGET</code> with a major version number. The value of this variable is typically handled by qmake or <a href="qmake-variable-reference.html#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="target-x-y-z"></a>
<h2 id="target-x-y-z">TARGET_x.y.z</h2>
<p>Specifies the extension of <code>TARGET</code> with version number. The value of this variable is typically handled by qmake or <a href="qmake-variable-reference.html#qmakespec">qmake.conf</a> and rarely needs to be modified.</p>
<a name="template"></a><a name="template"></a>
<h2 id="template">TEMPLATE</h2>
<p>Specifies the name of the template to use when generating the project. The allowed values are:</p>
<div class="table"><table class="generic">
<thead><tr class="qt-style"><th >Option</th><th >Description</th></tr></thead>
<tr valign="top" class="odd"><td >app</td><td >Creates a Makefile for building applications (the default). See <a href="qmake-common-projects.html#building-an-application">Building an Application</a> for more information.</td></tr>
<tr valign="top" class="even"><td >lib</td><td >Creates a Makefile for building libraries. See <a href="qmake-common-projects.html#building-a-library">Building a Library</a> for more information.</td></tr>

<tr valign="top" class="even"><td >aux</td><td >Creates a Makefile for not building anything. Use this if no compiler needs to be invoked to create the target, for instance because your project is written in an interpreted language.<p><b>Note: </b>This template type is only available for Makefile-based generators. In particular, it will not work with the vcxproj and Xcode generators.</p></td></tr>
<tr valign="top" class="odd"><td >vcapp</td><td >Windows only. Creates an application project for Visual Studio. See <a href="qmake-platform-notes.html#creating-visual-studio-project-files">Creating Visual Studio Project Files</a> for more information.</td></tr>
<tr valign="top" class="even"><td >vclib</td><td >Windows only. Creates a library project for Visual Studio.</td></tr>
</table></div>
<p>For example:</p>
<pre class="cpp">
TEMPLATE = lib
SOURCES = main.cpp
TARGET = mylib
</pre>
<p>The template can be overridden by specifying a new template type with the <code>-t</code> command line option. This overrides the template type <i>after</i> 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 <code>-t</code> option.</p>
<a name="translations"></a>
<h2 id="translations">TRANSLATIONS</h2>
<p>Specifies a list of translation (.ts) files that contain translations of the user interface text into non-native languages.</p>

win32:UI_DIR = c:/myproject/ui
</pre>
<a name="version"></a><a name="version"></a>
<h2 id="version">VERSION</h2>
<p>Specifies the version number of the application if the <code>app</code> <a href="qmake-variable-reference.html#template">template</a> is specified or the version number of the library if the <code>lib</code> template is specified.</p>
<p>On Windows, triggers auto-generation of an .rc file if the <a href="qmake-variable-reference.html#rc-file">RC_FILE</a> and <a href="qmake-variable-reference.html#res-file">RES_FILE</a> variables are not set. The generated .rc file will have the FILEVERSION and PRODUCTVERSION entries filled with major, minor, patch level, and build number. Each number must be in the range from 0 to 65535. More details about the generation of .rc files can be found in the <a href="qmake-platform-notes.html">Platform Notes</a>.</p>
<p>For example:</p>
<pre class="cpp">
win32:VERSION = 1.2.3.4 # major.minor.patch.build
else:VERSION = 1.2.3 # major.minor.patch
</pre>
<a name="version-pe-header"></a>
<h2 id="version-pe-header">VERSION_PE_HEADER</h2>
<p>Windows only. Specifies the version number, that the Windows linker puts into the header of the .exe or .dll file via the /VERSION option. Only a major and minor version may be specified. If <a href="qmake-variable-reference.html#version-pe-header">VERSION_PE_HEADER</a> is not set, it falls back to the major and minor version from <a href="qmake-variable-reference.html#version">VERSION</a> (if set).</p>

<h2 id="ver-pat">VER_PAT</h2>
<p>Specifies the patch version number of the library if the <code>lib</code> <a href="qmake-variable-reference.html#template">template</a> is specified.</p>
<a name="vpath"></a>
<h2 id="vpath">VPATH</h2>
<p>Tells qmake where to search for files it cannot open. For example, if qmake looks for <code>SOURCES</code> and finds an entry that it cannot open, it looks through the entire VPATH list to see if it can find the file on its own.</p>
