To get everything, type:
$ brew tap sampsyo/mspgcc $ brew install msp430-libc
libc is the top of the dependency chain, this should suffice to get everything you need.
$ msp430-gcc --version msp430-gcc (GCC) 4.7.0 20120322 (mspgcc dev 20120911) ...
These formulae are quick n' dirty and undoubtedly need some improvement (missing dependencies, brittle workarounds, etc.). I also haven't (yet) included
One manual step is required to get a working system. Annoyingly, since the
--prefix= compile option for each of these packages is different, each of the various tools can't find required files installed by other packages. To consolidate the various
lib pieces under a common directory, run:
$ $(brew --prefix)/Homebrew/Library/Taps/sampsyo/homebrew-mspgcc/addlinks.sh
This script symlinks everything from all the packages into
msp430 under the msp430-gcc keg. This means your root for the MSP430 toolchain is something like
/usr/local/opt/msp430-gcc/msp430 (which would be
/usr/local/msp430 on a "normal" installation).
