Build GCC 4.9.2 for C/C++ on CentOS 7

gistfile1.txt

sudo yum install libmpc-devel mpfr-devel gmp-devel

cd ~/Downloads
curl ftp://ftp.mirrorservice.org/sites/sourceware.org/pub/gcc/releases/gcc-4.9.2/gcc-4.9.2.tar.bz2 -O
tar xvfj gcc-4.9.2.tar.bz2

cd gcc-4.9.2
./configure --disable-multilib --enable-languages=c,c++
make -j 4
make install

So how to uninstall gcc built by this method? Thank you

Hi
maybe you need to run :
./contrib/download_prerequisites
before running "./configure ... " command

I used make -j$(nproc) and it went much faster too.

The command sequence below worked on my computer to update to version 7:
sudo yum -y install centos-release-scl
sudo yum -y install devtoolset-7
scl enable devtoolset-7 bash
gcc --version

The command sequence below worked on my computer to update to version 7: sudo yum -y install centos-release-scl sudo yum -y install devtoolset-7 scl enable devtoolset-7 bash gcc --version

this actually fixed an issue i had with node-canvas

npx node-pre-gyp rebuild -C ./node_modules/canvas

gcc version 4.8.5 was not working

Tremendous！
