Answer 1

내가 양조 업데이트 GCC를 실행했다.

brew upgrade gcc 
==> Upgrading 1 outdated package, with result: 
gcc 4.9.1 
==> Upgrading gcc 
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/gcc-4.9.1.mavericks.bottle.2.tar.gz 
######################################################################## 100.0% 
==> Pouring gcc-4.9.1.mavericks.bottle.2.tar.gz 
==> 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

Answer 2

g ++와 gcc의 심볼 링크를 변경하면 Mac OS 10.10에서 저에게 효과적입니다.

ls -al /opt/local/bin/gcc 
ls -al /opt/local/bin/g++ 
sudo rm /opt/local/bin/gcc 
sudo rm /opt/local/bin/g++ 
sudo ln -s /usr/bin/llvm-gcc /opt/local/bin/gcc 
sudo ln -s /usr/bin/llvm-g++ /opt/local/bin/g++ 
gem install therubyracer -v '0.12.1' 
sudo rm /opt/local/bin/g++ 
sudo rm /opt/local/bin/gcc 
sudo ln -s /opt/local/bin/g++-mp-4.9 /opt/local/bin/g++ 
sudo ln -s /opt/local/bin/gcc-mp-4.9 /opt/local/bin/gcc
