I just got a new gcc version by running brew update and brew upgrade. brew complained that brew link did not complete successfully:
~
✓ brew upgrade

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using:
brew link gcc
Possible conflicting files are:
/usr/local/bin/gfortran -> /usr/local/Cellar/gfortran/4.8.2/bin/gfortran
/usr/local/share/man/man1/gfortran.1 -> /usr/local/Cellar/gfortran/4.8.2/share/man/man1/gfortran.1
So I ran brew link gcc manually:
~
✓ brew link gcc
Linking /usr/local/Cellar/gcc/4.8.2... 25 symlinks created
Now when I tell brew to clean up I get the following warning:
~
✓ brew cleanup
Warning: Skipping (old) /usr/local/Cellar/gcc/4.8.2 due to it being linked
There are two gcc version in my Cellar:
~
✓ ls /usr/local/Cellar/gcc
4.8.2 4.8.2_1
Do I need both? I would like to remove the old version. How can I achieve that?
I solved it by running the following commands
brew unlink gcc
brew rm gfortran
brew cleanup
brew link gcc
It seems that gfortran was linked to the old gcc version.

When I try to install gcc49, I receive an error

I do not know where is the config.log located.
The correct way to install GCC 4.9 is to use
$ brew install homebrew/versions/gcc49
This way Homebrew will correctly resolve the missing dependencies and install them for you. You can find this version of gcc (or any other) using
$ brew search gcc49
homebrew/versions/gcc49
or
$ brew search gcc
gcc homebrew/versions/gcc47
homebrew/dupes/apple-gcc42 homebrew/versions/gcc48
homebrew/versions/gcc43 homebrew/versions/gcc49
homebrew/versions/gcc44 homebrew/versions/gcc5
homebrew/versions/gcc45 homebrew/versions/llvm-gcc28
homebrew/versions/gcc46
However, the dependency you are missing is not isl but isl011. You can install it with
$ brew install isl011
We can see that this is a dependency of gcc49 with
$ brew info gcc49
==> Dependencies
Required: gmp4 ✔, libmpc08 ✔, mpfr2 ✔, cloog018 ✔, isl011 ✔
The problem is caused by updated Xcode. Need run : "$ xcode-select --install"
I entered this:
brew install devil
and got this:
Error: devil cannot be built with any available compilers.
To install this formula, you may need to:
brew install gcc
So I reinstalled gcc and got this:

==> Caveats
GCC has been built with multilib support. Notably, OpenMP may not work:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60670
If you need OpenMP support you may want to
brew reinstall gcc --without-multilib

But I keep getting the same error when I try to install DevIL
i'm trying to install ruby using Homebrew, but every time i try I get this:

If you meant to cross compile, use `--host'.

What should I do?
if you install xcode-beta,you should run commond like this:
sudo xcode-select -switch /Applications/Xcode-beta.app/Contents/Developer
Try running this command : xcode-select --install. it works for me
By default brew install openmpi uses clang to create its wrapper.
I need to specify gcc-4.9(Homebrew installed) for the wrapper.
I have tried
$export CC=gcc-4.9
$brew install openmpi
$brew install --cc=gcc-4.9 openmpi
$brew install --with-gcc49 openmpi
$brew install -CC=gcc-4.9 -CXX=g++-4.9 -FC=gfortran -F77=gfortran openmpi
$brew install openmpi --cc=gcc-4.9
$brew install openmpi --CC=gcc-4.9 --CXX=g++-4.9 --FC=gfortran --F77=gfortran
Finally, I've modified the openmpi formula adding:
args = %W[
CC=gcc-4.9
CXX=g++-4.9
FC=gfortran
F77=gfortran
I still get
$mpicc --showme
clang -I/usr/local/Cellar/open-mpi/1.8.4/include -L/usr/local/opt/libevent/lib -L/usr/local/Cellar/open-mpi/1.8.4/lib -lmpi
Finally it was solved as follows:
1) Add environment variables for homebrew (you can also add these lines to your ~\.bashrc):
export HOMEBREW_CC=gcc-4.9
export HOMEBREW_CXX=g++-4.9
2) Rebuild and reinstall openmpi and its dependencies from source
brew reinstall openmpi --build-from-source
3) In the end you will get a message like:
==> Reinstalling open-mpi
==> Using Homebrew-provided fortran compiler.
This may be changed by setting the FC environment variable.

On my MacBook I had some conflicts with XCode 6.2, which were solved following this instructions
However, I decided to stay with the clang version to avoid issues with gfortran.
I'm trying to use RVM to install ruby 1.9.2 and 1.9.3. It fails because one of the dependencies seems to be gcc46, and rvm uses brew to install it.

Weird that the version is 4.2, since I have Xcode 4.6.3 and command line tools 4.6.3 installed. xcrun seems to be a problem too. Digging through the gcc46 logs leads to a failure to install gmp4:
in ~/Library/Logs/Homebrew/gmp4/config.log
