formulae for the MSP430 microcontroller compiler toolchain

homebrew-mspgcc

These are Homebrew formulae for mspgcc, the compiler toolchain for the MSP430 microcontroller. The repository includes binutils, gcc, libc, and the mcu files.

To get everything, type:

$ brew tap sampsyo/mspgcc
$ brew install msp430-libc

Since 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 gdb or mspdebug.

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).

homebrew-mspgcc's Issues

incorrect compiler flag in msp430-gcc.rb

multios = gcc --print-multi-os-dir.chomp

print-multi-os-dir

should be

print-multi-os-directory

msp430-gcc "/lib/cpp" fails sanity check

Below is the error I get on OSX 10.11 when installing msp430-gcc.

Unlinking libiberty fails

Line 41 in msp430-gcc.rb fails to execute because macOS has a fake gcc at /usr/bin/gcc that is actually just Clang. I'm not sure what exactly that piece was needed for or if it's still a problem, but you may want to find a different way to get that value.

Just a thought, as homebrew is a macOS platform, you may be working harder than necessary to use --print-multi-os-directory for that step.

binutils issue

msp430-binutils forces linking

for building msp430-gcc you are forced to link msp430-binutils but this is a problem if you already have binutils installed.
It would be much better if msp430-binutils would be keg_only.

msp430-gcc does not compile on yosemite

$ brew install msp430-libc

give the following error:

==> ../configure --target=msp430 --enable-languages=c,c++ --program-prefix='msp430-' --prefix=/usr/local/Cellar/msp430-g
==> make
checking for suffix of object files... configure: error: in /private/tmp/msp430-gcc20150331-75858-1ubybp9/gcc-4.7.0/build/msp430/libgcc': configure: error: cannot compute suffix of object files: cannot compile Seeconfig.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1
make: *** [all] Error 2

My Mac is running up to date yosemite and xtools.

Any idea what might be causing this?

libiberty.a no such file or directory

I had a problem, with the File.unlink as my libiberty.a was not in a subfolder x86_64.

/usr/local/Library/Taps/sampsyo/homebrew-mspgcc/msp430-gcc.rb:51:in `unlink'
Errno::ENOENT: No such file or directory - /usr/local/Cellar/msp430-gcc/4.7.0/lib/x86_64/libiberty.a

The patch in larsimmisch/homebrew-avr@8cc2a2e would check for that (using gcc) but my gcc does not have the option --print-multi-os-dir so this is only a workaround.

      if File.exists?("#{prefix}/lib/x86_64/libiberty.a")
        File.unlink "#{prefix}/lib/x86_64/libiberty.a"
      else
        File.unlink "#{prefix}/lib/libiberty.a"
      end
