Building and installing the ARM7 toolchain
==========================================

Before you can compile FC Selenite with gcc, you first need to build and
install the necessary toolchain targeting ARM7, the CPU core in the Calypso.
The current "official" GNU ARM toolchain for FreeCalypso consists of
binutils-2.21.1, gcc-4.5.4 and newlib-2.0.0 with a specific set of patches and
build configuration options.  All of the necessary bits can be downloaded here:

ftp://ftp.freecalypso.org/pub/GSM/FreeCalypso/toolchain/

Please note: the toolchain that is prescribed for FreeCalypso as above is
*believed* to be equivalent to the one that was once used by OsmocomBB, but
there are no guarantees.  Use any other toolchain at your own risk.

There is also a prebuilt toolchain put together by FreeCalypso community
contributor Das Signal:
