[Interest] Compile Qt for windows 32-bit using mingw-w64

[Koehne Kai]

Hi,

adding -m32 should work, but I haven't tested it since a while. The 'official' and bullet-proof method is to just install a native 32 bit toolchain (mingw-w64 based compilers usually can be downloaded as 32 bit or 64 bit).

Regards

Kai

Subject: [Interest] Compile Qt for windows 32-bit using mingw-w64

Dear all,

I am still using the old mingw 32-bit shipped with Qt for my 32 bit
builds, and mingw-w64 for 64-bit. In order to harmonize everything and
to switch to c++11, I'd like to recompile Qt for 32 bit platforms with
the new compiler.

Do I simply need to add -m32 to the compiler and linker flags of
qmake.conf in mkspecs? Or is that more complicated?

Thanks,

Etienne
