NOTE:
|
|
This formula provides components that were removed from XCode in the 4.2
|
|
release. There is no reason to install this formula if you are using a
|
|
version of XCode prior to 4.2.
|
|
|
|
This formula contains compilers built from Apple's GCC sources, build
|
|
5666.3, available from:
|
|
|
|
https://opensource.apple.com/tarballs/gcc
|
|
|
|
All compilers have a `-4.2` suffix. A GFortran compiler is also included.
