Just add -m64 on the config line, like this: ./config no-shared zlib -m64 -IC:/_64/msys_630/1.0/local/include \ -LC:/_64/msys_630/1.0/local/lib --prefix=C:/_64/msys_630/1.0/local This is weird, though... what config target did you get when configuring? Ideally, you should have gotten 'mingw64', which already uses the -m64 flag, so what gives? If you show us the config output, maybe we can help you figure out what actually goes wrong...
