[Qt-interest] Recompile Qt with different -march option

[Etienne Sandré-Chardonnal]

Dear all,


I would like to recompile qt-mingw using the -march=pentium4 flag. Who knows
how to do that?

Actually, I have trouble when inserting SSE instructions in my application.
The code compiles well with -march=pentium4, but the app segfaults when SSE
containing functions are called by QT functions (through signals/slots for
instance), since they do not 16-byte align the stack. I suppose this is
because Qt libraries were not built with a SSE-compatible -march target.

Thanks,

Etienne
