CentOS upgrade support to C++11, gcc4.8.2

Upgrade to 4.8 "This should be the latest, but the online search has reached 5.2, feeling behind a bit more stable, of course, there is this version is the new one of the most used"

wget Http://people.centos.org/tru/devtools-2/devtools-2.repo-O/etc/yum.repos.d/devtools-2.repo

Or

Cd/etc/yum.repos.dwget Http://people.centos.org/tru/devtools-2/devtools-2.repo

And then

Yum Install DEVTOOLSET-2-GCC devtoolset-2-binutils devtoolset-2-gcc-c++

This will install the files on the

/opt/rh/devtoolset-2

If you want the editor to handle it, this action

Export CC=/OPT/RH/DEVTOOLSET-2/ROOT/USR/BIN/GCC Export Cpp=/opt/rh/devtoolset-2/root/usr/bin/cppexport CXX=/OPT/RH /devtoolset-2/root/usr/bin/c++

If you want GCC to replace the local, of course, it is not really to replace, just put him under our/usrlocal/bin, do not have to control the system comes with the "/usr/bin".

Ln-s/opt/rh/devtoolset-2/root/usr/bin/*/USR/LOCAL/BIN/HASH-RGCC--version
