copied!<h3>Compiling external libraries with QtCreator/gcc</h3> <p>If you own the source code of your libraries this is the .pro file to make an external library (.dll and .a) or Framework (on Mac OS X) from them:</p> <pre><code>TEMPLATE = lib INCLUDEPATH = <your-include-paths> HEADERS += <your-headers> SOURCES += <your-sources> TARGET = MyLib /* The name of your libary */ /* Win32: To generate a MyLib.dll and libMyLib.a (gcc) or MyLib.lib (MSVC) file */ win32 { CONFIG += dll } /* Just in case you need to generate Mac Frameworks: */ macx { CONFIG += shared lib_bundle FRAMEWORK_HEADERS.version = Versions FRAMEWORK_HEADERS.files += <your library headers> /* Example: FRAMEWORK_HEADERS.files += /path/to/your/lib/MyLib.h */ FRAMEWORK_HEADERS.path = Headers QMAKE_BUNDLE_DATA = FRAMEWORK_HEADERS VERSION = 0.5.0 // a framework version you can define } </code></pre> <h3>Adding external libraries to your QtCreator/gcc project</h3> <pre><code>/* your project settings */ /* If you compile on windows */ win32 { /* If you compile with QtCreator/gcc: */ win32-g++:LIBS += /path/to/your/libMyLib.a /* IF you compile with MSVC: */ win32-msvc:LIBS += /path/to/your/libMyLib.lib } /* If compile on Mac and want to link against a framework */ macx { LIBS+= -framework MyLib QMAKE_FLAGS += -F/path/to/MyLib } </code></pre> <p>Note that to use external libraries with <code>gcc</code> you need the libMyLib.a file that contains the linking information. The <code>libMyLib.lib</code> are generated by MS Visual Studio and can't be processed by gcc afaik!</p>
