Compiling for mingw32 under Cygwin

ruby-talk

Hi there,

I'm trying to compile Ruby under Cygwin, but I want to target mingw32. Although I've got the mingw32 tools installed, the ./configure step doesn't spot them. Has anyone had any luck with this? Just setting CFLAGS='-mno-cygwin' isn't enough, it seems.

% ./configure --with-gcc='gcc -mno-cygwin'

Thanks :slight_smile: Looks like that's working - make test passes, at least.

I'd assumed that would be equivalent to setting CFLAGS, but it doesn't look like it is. Why isn't it, and should it be?

CFLAGS have no effect to a preprocesser. Leaving it as cygwin
would cause problems.
