I have a git repository which I can build with:
./autogen.sh
./configure
make
sudo make install
Now I want to cross compile it for windows with the mingw32/mingw-w64 cross compiler.
I tried it with
export CXX=/usr/bin/x86_64-w64-mingw32-gcc
but that didn't work for me.
I have configure eclipse that I can compile windows executables as well, that works, but only with plane c code. Now I need external libraries, which I have to compile for windows as well.
As described on a(n old, but mostly correct) page of the MinGW-w64 wiki (written by yours truly a long time ago):
./configure --host=x86_64-w64-mingw32
should do the trick if the package doesn't need special handling for Windows.
