Hi,
I'd like to cross compile a scheme app for OpenWRT (MIPS architecture). Has anyone attempted to do this? How can I approach this?
The main problem is that I can't have a running MIPS system in a virtual machine. So cross-compilation seems to be the only option.

I haven't tackled this sort of problem myself, but presumably you would use gsc -link to compile the Scheme files to C and generate a link file, and then pass those to your C cross-compiler.

Well, I'm not familiar with all the options that need to be passed to gcc for compiling. Right now, I'm getting a linker error.

Try to put '-lgambc' last in your linking command line.
HTH,
In case it's useful, LambdaNative supports cross-compiling Gambit Scheme apps using the OpenWrt SDKs (tested on one of the MIPS targets from the Attitude Adjustment (12.09) release).

Thanks. It looks like an interesting project. I did not manage to get it up & running though, I can't remember right now why.
In the meantime I have found a way to cross compile scheme apps. When running gsc with -exe and -verbose, it will print out the gcc command lines it uses. It looks like I was missing -lutil -ldl -lm. The complete command line looks like this (not including all the optimization options):
mips-openwrt-linux-gcc -D___SINGLE_HOST -I"/home/roti/programs/gambit.mips-openwrt/include" test.c test_.c /home/roti/programs/gambit.mips-openwrt/lib/libgambc.a -lutil -ldl -lm
