[solved]In Qt Creator, how to set project property for both MinGW and VC compiler?

kathy

I know how to use MinGW or Visual C++ compiler for Qt Application on Windows. But I would like some way to auto select the pro setting.

For example:

inside my pro file, I need to set boost lib:

for minGW

LIBS += C:/MinGW/boost_1_46_1/lib/libboost_thread.a
LIBS += C:/MinGW/boost_1_46_1/lib/libboost_date_time.a

for VC++

LIBS += C:/VC++/boost_1_46_1/lib/libboost_thread-vc90-mt-1_46_1.lib
LIBS += C:/VC++/boost_1_46_1/lib/libboost_date_time-vc90-mt-1_46_1.lib

How to change the pro file so that I do not need manually comment out the LIBS for different compiler?

You can use scopes, like

win32-g++ {
LIBS += C:/MinGW/boost_1_46_1/lib/libboost_thread.a
LIBS += C:/MinGW/boost_1_46_1/lib/libboost_date_time.a
}
win32-msvc*{
LIBS = C:/VC+/boost_1_46_1/lib/libboost_thread-vc90-mt-1_46_1.lib
LIBS = C:/VC+/boost_1_46_1/lib/libboost_date_time-vc90-mt-1_46_1.lib
}

I actually hate to hardcode pathes like those into the build system: This will break as soon as you hand it over to somebody else!

Maybe you could use environment variables or something instead. Those are a bit easier to change and document (set BLAH to "/some/path" instead of edit "blah.pro", search for the line reading LIBS += "/some/path" and replace it with the path you need.

Unfortunately qmake does not support proper configuration steps to do the whole configuration properly.

Maybe we can write like this:

@
OPENCVPATH_MSVC = D:/Qt/OpenCV-2.1.0-vs2008
OPENCVPATH_MINGW = D:/Qt/OpenCV-2.1.0-mingw

win32-msvc*{
INCLUDEPATH += $${OPENCVPATH_MSVC}/include
CONFIG(debug, debug|release) {
LIBS+=-L$${OPENCVPATH_MSVC}/lib/
-lcxcore210d
-lhighgui210d
} else {
LIBS += -L$${OPENCVPATH_MSVC}/lib/
-lcxcore210
-lhighgui210
}
}

win32-g++{
INCLUDEPATH += $${OPENCVPATH_MINGW}/include
LIBS += -L$${OPENCVPATH_MINGW}/lib
-lcxcore210
-lhighgui210
}

unix:LIBS += -lcv
-lhighgui

LIBS += -LC:/MinGW/boost_1_46_1/lib/
win32-g++ {
LIBS += -lboost_thread -lboost_date_time
} else: win32-msvc* {
LIBS += -lboost_thread-vc90-mt-1_46_1 -lboost_date_time-vc90-mt-1_46_1
}
