Yes, you need to do a fair amount of extra work in order to get
-mno-cygwin to work.
- You'll need the various target libraries (libgcc, libstdc++,
libsupc++, libgfortran, libgomp, libada, libgcj, etc.) of the same
version of gcc (and same configure options) built for MinGW and put in
the $libexecdir/gcc/$target/$version (assuming you used
--enable-version-specific-runtime-libraries, otherwise without
- You'll need symlinks for $tooldir/include, $tooldir/lib, and
$tooldir/bin (where $tooldir defaults to $prefix/$target) as well as for
the compiler subexecutables in $libexecdir/gcc/$target/$version pointing
to the Cygwin ones.
The best way to go is look at the packaged version of gcc and see how
All in all I think it would be a lot simpler just to build a straight
MinGW cross compiler. Then you'd just use "i686-pc-mingw32-gcc" instead
of "gcc -mno-cygwin". And in fact this is the eventual plan as this
-mno-cygwin "fake/pseudo cross-compiler" thing is really the wrong way.
