Link errors: undefined reference to `_Unwind_Resume' and '__gxx_personality_v0'

[jonks]

I created a default Gui project (mo modifications whatsoever) and, using Creator, confirmed that it compiled and linked. (Dynamic linkage to QT libs).

I then opened a cmd prompt. Set my environmental variables to the various Qt bin dirs, then ran qmake and mingw. I get an odd linker error.

I've checked other posts with this problem and in their cases it turned out to me a mingw version problem. In my case I only have the mingw that was installed by QT Creator.

The error is below.
Do you have any idea why the cmd line compile fails in my case?

My QT related path variables are:

Running C:\Qt\2010.04\bin\qtenv.bat fixes the problem.

It works for me. thx.

just to explain the problem. is that you need to compile Qt app with the same compiler that compiled Qt itself (like the one's inside the SDK). You can also recompile Qt with yours.
some GCC are usign SJLJ and some DW2.
