Hello, I believe I have successfully got an unregisterised version of ghc 6.4.2 compiled for arm/linux. Details: ------- I only had to do a minor bit of hacking -- this bug contains the details of what went wrong: http://hackage.haskell.org/trac/ghc/ticket/762 My target platform is the nokia 770 which runs linux and has an arm9 processor. I compiled ghc using the standard nokia 770 cross-development tools. These consist of a debian-based distro named maemo running inside scratchbox using QEMU to emulate the ARM processor. I have successfully compiled a "hello, world!" program and run the executable on the real nokia 770 device. What Next? ---------- The next step appears to be to registerise the build. I found a document that describes the C calling conventions for the ARM: http://www.arm.com/miscPDFs/8031.pdf I think the next step is to add an ARM section to: ghc/includes/MachRegs.h Is there some sensible method for doing this and testing it before I tackle the other pieces ? Thanks! j.
