上回用了比較複雜的方法來升級gcc,昨天找到另外一個更簡易的方法,方法如下,如法炮製.
#wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
#rpm --import http://ftp.scientificlinux.org/linux/scientific/5x/x86_64/RPM-GPG-KEYs/RPM-GPG-KEY-cern
#yum install devtoolset-2-gcc-c++-4.8.2-15.1.el6
以上步驟做完後,在/etc/profile裡加上這一行
source /opt/rh/devtoolset-2/enable
然後在terminal裡輸入以下就行了
#source /etc/profile
檢查gcc版本
#gcc --version

在那網頁裡也有網友說可以直接用devtoolset-3,我還沒試.
