I have read similar topics here, but unfortunately these solutions does not help me.
I would like to recompile all installed software (or at least some formulas) from Homebrew using
Is it possible to force
Homebrew to use specific compiler (e.g.
gcc) and compiler options (e.g. std library to use for linking)?
I have tried to set all kinds of environment variables, but it does not help :/ ?
0/> env | grep CC HOMEBREW_CC=gcc CC=/usr/local/bin/gcc 0/kpykc> echo $PATH /Users/kp/kpykc/devel/bin:/opt/ros/indigo/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/texbin 0/kpykc> ls -la /usr/local/bin/g??-?.? lrwxr-xr-x 1 kp admin 31 Nov 24 16:23 /usr/local/bin/g++-4.9@ -> ../Cellar/gcc/4.9.2/bin/g++-4.9 lrwxr-xr-x 1 kp admin 31 Nov 24 16:23 /usr/local/bin/gcc-4.9@ -> ../Cellar/gcc/4.9.2/bin/gcc-4.9 0/kpykc> ls -la /usr/local/bin/g[c+][c+] lrwxr-xr-x 1 kp admin 22 Nov 11 23:54 /usr/local/bin/g++@ -> /usr/local/bin/g++-4.9 lrwxr-xr-x 1 kp admin 22 Nov 11 23:53 /usr/local/bin/gcc@ -> /usr/local/bin/gcc-4.9
Also tried to use this solution.
The reason for doing that is that I want to compile some code* with gcc and link against libraries installed from brew. But it seems that gcc can't link to libs built by clang. On other side it lacks support of some C++11 features which are required by the program* i would like to compile.
So only solution that I see, is to recompile all needed libs with gcc.
Thank you for help.

In particular I have troubles with code which uses

HEAD version from
I suspect my problem is also connected with this bug. But it should be fixed in
HEAD, I think so.
