← #15

The gcc packages from ftp://mirror.switch.ch/pool/4/mirror...ts/devtoolset/
installs to /opt/centos/devtoolset-1.1/root/usr/bin/{gcc g++}


#14 :
For the newly installed "gcc47 and g++47", please do :
$ which gcc47
$ which g++47
$ gcc47 --version
$ g++47 --version
( And / or $ gcc47 -v && g++47 -v ).

The "export CC=gcc47 CXX=g++47" is used when you are compiling.
Like $ export CC=gcc47 CXX=g++47 && ./configure

-

true you can export
but if you are going to use the CERN build
then why not use the already installed script

o.k that what worked for me:

cd /etc/yum.repos.d
wget http://people.centos.org/tru/devtool...tools-1.1.repo
yum --enablerepo=testing-1.1-devtools-6 install devtoolset-1.1-gcc devtoolset-1.1-gcc-c++

vim /etc/yum.repos.d/devtools-1.1.repo
paste all of this:
[DevToolset-2]
name=RedHat DevToolset v2 $releasever - $basearch
baseurl=http://puias.princeton.edu/data/puias/DevToolset/$releasever/$basearch/
enabled=1
gpgcheck=0

yum install devtoolset-2-gcc-4.8.1 devtoolset-2-gcc-c++-4.8.1
/opt/rh/devtoolset-2/root/usr/bin/gcc --version
ln -s /opt/rh/devtoolset-2/root/usr/bin/* /usr/local/bin/
hash -r
gcc --version


thanks for the help every one
