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
Solution

  • QMAKE_LDFLAGS=-m32 solved my problem. Thank you guys
