Issue with building 32 bit Qt 5.2.1 applications in 64 bit operating system (centos with gcc 4.8.2)

  • During building Qt 5.2.1 applications (32 bit) in CentOS (64 bit with gcc 4.8.2), I got following error:
    @main.o: could not read symbols: File in wrong format
    collect2: error: ld returned 1 exit status@

    Note that I have inserted following statement in the qt project file (Pro file):

    @QMAKE_CXXFLAGS +=-m32@

    Are you trying to build a 32 bit application with a 64bit Qt version ?
