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.
=== 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(FIXME: Should be rechecked, the information might be outdated)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.
