If you are programming in C++ there are chances that you use Boost C++ libraries as well. I couldn't find pre-built Boost libraries for ARM, so I had to compile them myself. Since I don't have a cross-compiler ready, I compiled them on the Rasp Pi (B model) itself, so it took quite a while (about 4 hours), but it was worth it
I had to use an external USB drive for swap storage because the build kept failing due to RAM shortage.
I used Arch distribution (29/4/2012) and I compiled with the latest GCC in repositories (4.7.0).
I've uploaded the binaries if you don't want to compile on your own.
Whole Boost 1.49 package (sources, headers, documentation):
Libraries only (static + dynamic)
