If you are looking to add cross-compilation to GHC, the first thing I'd look at is detaching the choice of native code generator from the preprocessor and hooking it up to a front-end command-line option instead :) We already compile in all the NCG backends, so that should be quite straightforward. What's much harder is arranging the rest of your cross-compilation environment - assembler, linker etc., and making sure you're using the right configuration parameters from the target machine for the build. It's generally easier to get an unregisterised port working first, and then use that to bootstrap an NCG/registerised version. Someone on IRC (his username is dumael, not sure what his real name is) has already been working on an ARM native code generator for GHC recently. Interesting, I didn't know that. There's also the iPhone GHC port, which is unregisterised, I believe. The recent LLVM back-end development should also make it pretty simple to generate code for other platforms (especially if we have a nice way to pass front-end options to the code generators) Definitely, I think that will be a nice side-effect of the LLVM backend.

Compiling to ANSI C
I am (in fact we are) working to make Haskell code to run on an ARM Linux machine called GP2X Wiz, the open-source based handheld game console. I wish to finally make a Haskell cross-compiler for ARM Linux, and for now I am trying to make main = putStrLn Hello, World! to run on the machine. At first I did $ ghc hello.hs -o hello -fvia-C -keep-hc-files and tried to use the generated hc file, but figured that the code is (or at least some code in the included headers is) x86-dependent. I heard that the GHC can compile to ANSI C, and I want to use it as an intermediate code to ARM Linux before we can actually port the GHC to it. Is there any specific option I have to give in order to generate an ANSI C code from a Haskell source code? ___ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users

Jhc compiles to ANSI C and has been tested with other ARM targets and works fine. It may be suitable for your needs.
