qmake Variable Reference

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:

• release - Compile with optimization enabled, ignored if "debug" is specified
• debug - Compile with debug options enabled
• warn_on - The compiler should emit more warnings than normally, ignored if "warn_off" is specified
• warn_off - The compiler should only emit severe warnings.

These options define the application/library type:

• qt - The target is a Qt application/library and requires the Qt header files/library. The proper include and library paths for the Qt library will automatically be added to the project.
• opengl - The target requires the OpenGL (or Mesa) headers/libraries. The proper include and library paths for these libraries will automatically be added to the project.
• 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.
• dll - The target is a shared object/DLL.The proper include paths, compiler flags and libraries will automatically be added to the project.
• staticlib - The target is a static library (lib only). The proper compiler flags will automatically be added to the project.
• plugin - The target is a plugin (lib only). This enables dll as well.

These options are used to set the compiler flags:

• exceptions - Exception support is enabled
• rtti - RTTI support is enabled
• stl - STL support is enabled

These options define specific things depending on the platform and/or template:

• 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.

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
    }
