Unable to link with library in qt creator 2.8.1 with MinGW 4.8

Well I just gave qt creator a go and tried to port my project from eclipse CDT...but when I link with libraries compiled with MinGW 4.7.2, build fails with undefined like these :
"c:/qt/qt5.1.1/tools/mingw48_32/bin/../lib/gcc/i686-w64-mingw32/4.8.0/../../../../i686-w64-mingw32/lib/../lib/crt2.o:crtexe.c:(.text+0x14): undefined reference to _newmode' c:/qt/qt5.1.1/tools/mingw48_32/bin/../lib/gcc/i686-w64-mingw32/4.8.0/../../../../i686-w64-mingw32/lib/../lib/crt2.o:crtexe.c:(.text+0x36): undefined reference to _dowildcard'

Has anyone encountered these? How did you fix it? Thanks for any answer.

Hi and welcome to devnet,

AFAIK, mixing libraries build from various MinGW versions will not work (I'll be happy to be proven wrong though)

@SGaist Thanks alot for that clarification.

SGaist

You're welcome

Just to clarify, I was thinking between minor releases (major also), patch release should be fine.
