Avoid using The Unarchiver.app mac app to extract the tar.bz2 archive. It messes up the symlinks, and things wont work. Instead, use the Archive Utility.app built into OS X (by right clicking the archive and selecting from open with). (Tested using OS X 10.9.3, The Unarchiver 3.9.1)

I went a bit crazy with the script. Uploaded the bzip2 to S3 for speed (launchpad was very slow), made it idempotent, and made it installable via a one liner:

bash <(curl -fsSL https://gist.github.com/ericboehs/0cea8c5778aff405c445/raw/install_gcc_arm.sh)

Next step, homebrew formula.

All that work and there's already a homebrew formula. Should have googled harder:

brew tap PX4/homebrew-px4
brew update
brew install gcc-arm-none-eabi

Unfortunately, the homebrew formula doesn't seem to correctly setup the includes necessary to build the core-firmware.

The latest firmware requires GCC 4.8:

brew install gcc-arm-none-eabi-48

(this fixes the "stdatomic.h: No such file or directory" error.)

The latest firmware requires GCC 4.8

This took me far too long to find the solution. So for some Google juice, this solves these errors:

../CC3000_Host_Driver/evnt_handler.c:61:23: fatal error: stdatomic.h: No such file or directory

...

obj/startup/startup_stm32f10x_md.o: In function `LoopFillZerobss':
core-firmware/build/../startup/startup_stm32f10x_md.S:98: undefined reference to `SystemInit'

...

obj/src/wifi_credentials_reader.o: In function `WiFiCredentialsReader::print(char const*)':
core-firmware/build/../src/wifi_credentials_reader.cpp:106: undefined reference to `Delay'

You'll also want to uninstall the older version first:

brew uninstall gcc-arm-none-eabi
brew install gcc-arm-none-eabi-48

And throw in a make clean all for good luck. And make sure you have the latest, unmodified versions of the 3 git repos.

I tried the homebrew route on a fresh machine... worked perfectly! Thanks all!

Step 1 - Install Homebrew
http://brew.sh/

Step 2 - Install GCC Arm Toolchain

brew tap PX4/homebrew-px4
brew update
brew install gcc-arm-none-eabi-48

Step 3 - Profit!

Maybe I am missing something but why not just download pre-build and validated toolchain from the ARM dev portal?:

The last two comments were pretty useful. I could understand downloading the binaries and putting them in the /usr/local directory and setting your PATH, however I had no idea what home-brew would do to install things, where it would put them, or whether the version it would install will be the same one.

So while I did download (but did not install) "gcc-arm-none-eabi-7-2017-q4-major-mac.tar.bz2", I decided to try the "brew install caskroom/cask/gcc-arm-embedded" first.

This worked. The cask room formula is here https://github.com/caskroom/homebrew-cask/blob/master/Casks/gcc-arm-embedded.rb, which is pretty readable, and it just downloaded the same file as I initially downloaded manually:

==> brew cask install caskroom/cask/gcc-arm-embedded
==> Satisfying dependencies
==> Downloading https://developer.arm.com/-/media/Files/downloads/gnu-rm/7-2017q4/gcc-arm-none-eabi-7-2017-q4-major-mac.tar.bz2

gcc-arm-embedded was successfully installed!

So I learned something about home-brew as well as got an easy install.

After this install, all the documentation is under:
/usr/local/Caskroom/gcc-arm-embedded/7-2017-q4-major/gcc-arm-none-eabi-7-2017-q4-major//share/doc/gcc-arm-none-eabi/
For example:
file:///usr/local/Caskroom/gcc-arm-embedded/7-2017-q4-major/gcc-arm-none-eabi-7-2017-q4-major/share/doc/gcc-arm-none-eabi/html/binutils.html/index.html

Example code and example startup assembler files for M0, M3, M4, M7 are under
/usr/local/Caskroom/gcc-arm-embedded/7-2017-q4-major/gcc-arm-none-eabi-7-2017-q4-major//share/gcc-arm-none-eabi/samples

The next thing you're going to need to do however is download and install CMSIS, the ARM CPU common headers and run time libraries.

https://developer.arm.com/embedded/cmsis
https://github.com/ARM-software/CMSIS_5/releases/tag/5.3.0

Lastly you're going to need the header files for the peripherals from the manufacturer of your specific ARM part.
