Let me correct myself, I don't think that's good advice. Tempting as this is:
$ env CSC_OPTIONS='-feature windows' ./i686-w64-mingw32-chicken-opengl-1.22.sh
<http://i686-w64-mingw32-chicken-opengl-1.22.sh/>
It will probably make everything think it's on windows, including macro
expansion and the first host-side build of the cross compilation. That is not
what we want.
Is PLATFORM=cross-linux-mingw set correctly in your make invokation when
building Chicken? If I'm not mistaken, that should first build on the host
(PLATFORM=linux) and then build things for the target (PLATFORM=windows).
Hope this gives you some pointers. cross-compilation is hard, and even harder
with macros/syntax!

Hi,
I don't know if it's of much help, but it seems your cond-expand is using
the fallbavk (-LX11 -L -lGLU), not the windows-specific. Probably because
you're not _actually_ on windows.
Perhaps try to edit your opengl.ogg file directly and see if that work.
Otherwise, see if you can inject a register-feature! call [1] before the build.

Hello,
I am on Linux (64-bit).
I try to cross compile the opengl egg from Linux (64-bit) to Windows
(32-bit).

<https://code.call-cc.org/egg-tarballs/5/opengl/opengl-1.22.tar.gz>
My first attempt was with this script:
$ cat i686-w64-mingw32-chicken-opengl-1.22.sh
<http://i686-w64-mingw32-chicken-opengl-1.22.sh>
set -e

DIR="opengl-${VERSION}"
DESTDIR="/tmp/${NAME}-${VERSION}"
tar xvf ${DIR}.tar.gz
cd ${DIR}
DESTDIR=${DESTDIR} CHICKEN_EGG_CACHE=/tmp/chicken-cache
i686-w64-mingw32-chicken-install
Result:
$ ./i686-w64-mingw32-chicken-opengl-1.22.sh

As we can see, the problem here is that GLU is not found.
I think this is normal for a Windows (32-bit) target because Windows should use "-lopengl32" and
"-lglu32" instead of "-lGL" and "-lGLU".
This is what we can see in opengl-1.22/opengl.egg:

So, I am stuck here.
Can you help me please?
Thank you.
