To compile osmocomBB or SIMtrace for the target we need a GNU Toolchain for ARM. There are various pre-compiled toolchains available but not all of them will produce working firmware. We will try to support all these configurations but it might take a while to identify the source of a problem. If you have persistent errors when compiling, try using a different package. === Build one from source === If you want to build your own toolchain, known to be working with OsmocomBB, see here: [wiki:GnuArmToolchain]. This is the best option to get a fairly recent GCC, and this is the option used by several Osmocom-BB developers. === GNUArm === The toolchains that are known working are the [http://www.gnuarm.com GNUArm.com] ones. Only x86_64 versions are usable [http://gnuarm.com/bu-2.16.1_gcc-4.0.2-c-c++_nl-1.14.0_gi-6.4_x86-64.tar.bz2 here]. The ones for x86 are based on 3.4.3 which it too old to compile Osmocom-BB properly. For amd64 {{{ wget http://www.gnuarm.com/bu-2.16.1_gcc-4.0.2-c-c++_nl-1.14.0_gi-6.4_x86-64.tar.bz2 tar xf bu-*_gcc-*-c-c++_nl-*_gi-*_x86-64.tar.bz2 mv gnuarm-* ~/gnuarm }}} To be able to use the toolchain, add the crosscompilers to your PATH {{{ export PATH=~/gnuarm/bin:$PATH }}} === Ubuntu packages === gnuarm packages from following ppa are known to work on ubuntu 10.10 to build osmocom-bb. They are known '''not''' to work for SIMtrace {{{ sudo add-apt-repository ppa:bdrung/bsprak sudo apt-get update sudo apt-get install arm-elf-toolchain }}} (FIXME: Should be rechecked, the information might be outdated) === Mac OS X === Apparently the arm-elf-gcc 4.3.2 from ports for mac os x can compile the sourcecode as well after symlinking /opt/local/bin/arm-elf-ranlib to /opt/local/bin/arm-elf-linux-ranlib and /opt/local/bin/arm-elf-strip to /opt/local/bin/arm-elf-linux-strip. If you omit the links, there will be unresolvable references to symbols in the libraries.
