I'm happy to announce the first GDC ARM beta on behalf of the GDC team :) ARM support is now at a point where the automated tests (test suite, unit tests) pass and we're ready for feedback from real world usage. All changes have been fully integrated into the standard GDC sources which also means we're currently using the 2.064 frontend. ARM support is currently limited to ARM/GNU Linux, i.e. GlibC. (This especially means Android and bare metal programming are not officially supported).
Please report all bugs to http://bugzilla.gdcproject.org/ If you're sure that the bug is a bug in phobos/druntime/DMD frontend and not GDC specific please report it to https://d.puremagic.com/issues ==== Getting the ARM beta ==== * All necessary code changes have been merged into Druntime, Phobos and GDC and you can simply get the latest GDC sources and build them on ARM. ( http://wiki.dlang.org/GDC/Installation/Generic ) * GDC is also part of the official Archlinux ARM repositories. To get GDC for Archlinux ARM, simply use these commands: pacman -S gdc libgphobos-devel You can also get dub on Archlinux ARM by executing pacman -S dub Many thanks to Dicebot for maintaining the Archlinux packages. * We provide binary cross compilers for windows X86 (32/64bit) and Linux x86 (32/64bit). We also provide 'native' compilers which run directly on ARM machines. http://gdcproject.org/downloads/ Note: Linux distribution packages or building from source should be preferred. ==== Precompiled GDC binaries ==== Precompiled toolchains are available for ARM hardfloat and ARM softfloat systems. These toolchains target systems with relatively recent glibc and linux kernel (GlibC >= 2.14, Linux >= 2.6.32). To check if you need the hard- or softfloat version run gcc -v where gcc is a working gcc for your ARM target. Then look for --with-float= in the output: --with-float=soft <==> softfloat --with-float=hard <==> hardfloat --with-float=softfp: We have no special binaries for these systems. Either compile GDC from sources or use the softfloat binaries. The softfloat binaries should work in 99% of all cases. The only known exception is using floating point functions in fibers, a 'softfp' toolchain is required in this case. To compile for ARM simply use this gdc executable: ./arm-gdcproject-linux-gnueabi[hf]/bin/arm-gdcproject-linux-gnueabi[hf]-gdc Note: The toolchain directories are write protected. If you want to change this, use chmod +w -R arm-gdcproject-linux-gnueabi[hf]. For more information on how to use additional libraries with the cross compilers, see http://crosstool-ng.org/hg/crosstool-ng/raw-file/e11a8a2e225d/docs/5%20-%20Using%20the%20toolchain.txt ==== Known issues ==== Known ARM-specific issues * std.internal.math.gammafunction.d is not ported yet (Help here is very appreciated!) * Array ops are evaluated in reverse order (WIP, FE 2.065) http://bugzilla.gdcproject.org/show_bug.cgi?id=8 Known issues with the binary builds * If you extract 7z files and are asked if you want to overwrite files, answer yes (toolchains are built on case sensitive filesystems, extracting on case insensitive filesystems will cause this warning) * Use the arm-...-gdc.exe executables and not bin/arm.../gdc.exe. * Unfortunately there's no multilib support for now. We use crosstool-NG to build these toolchains and multilib support in crosstool-NG is broken. However, this might change in the next few months.
