Qt has suddenly started giving me a load of errors

[tom989]

I compiled qt statically and everything worked fine.

But somehow, and I don't know how, I've changed something and now qt is giving me a load of errors. I use qt4 and mingw.

I get a huge number of compiler errors starting with:

qtmain_win.cpp:-1: error: undefined reference to `__gxx_personality_sj0'
qtmain_win.cpp:-1: error: undefined reference to `_Unwind_SjLj_Register'

What have I done!?

Really? No-one can help?

4 hours on New Year's day .... are you really that impatient?

I Googled "g++ __gxx_personality_sj0" and look what was the very first hit:

Have you recently upgraded g++ and not rebuilt your static Qt/project with it?
Are you mixing libraries/object built with different exception handling?
