gcc 4.8.5 설치
- in UBUNTU
- mkdir gcc
- tar -zxvf gcc-4.8.5.tar.gz
- cd gcc-4.8.5
- ./contrib/download_prerequisites
- ./configure --prefix=/usr/local/gcc-4.8.5 --enable-checking=release --enable-languages=c,c++ --disable-multilib
- make -jN
- make install
- vi /etc/profile
export GCC=/usr/local/gcc-4.8.5 export C_INCLUDE_PATH=$GCC/include/c++/4.8.5/ export CPLUS_INCLUDE_PATH=$GCC/include/c++/4.8.5/ export LD_LIBRARY_PATH=$GCC/lib64:$PPL/lib:$LD_LIBRARY_PATH export PATH=$GCC/bin:$PATH
- source /etc/profile
- apt-get을 이용해 설치
- In su
# apt-get install build-essential # add-apt-repository ppa:ubuntu-toolchain-r/test # apt-get update # apt-get install gcc-4.9 g++-4.9 cpp-4.9
- Using update-alternatives
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.6 40 --slave /usr/bin/g++ g++ /usr/bin/g++-4.6 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.4 40, 60은 priority이며 숫자가 높을수록 자동적으로 버젼을 설정해주는 선호도가 높다.
- sudo update-alternatives –config gcc (0번: gcc-4.4를 선택함)
- in Scientific Linux (gcc 4.8.2)
- wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
- yum install devtoolset-2
- vi /etc/bashrc에 source scl_source enable devtoolset-2 추가
- gcc –version
- gcc 4.9.2
- rpm -Uvh ~.rpm
- yum install devtoolset-3
