How to set up an additional glibc compiler on centOS

I'm using CentOS 7 and it is having glibc version 2.17. I want to set up additional glibc compiler(same or another version) on this OS. Please anyone help me in this.

Solution

  • Let us assume you want to install 2.14 along 2.17 on centOS 7 and use it to compile your projects, just follow the steps below :

    mkdir ~/glibc_install; cd ~/glibc_install 

wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz

tar zxvf glibc-2.14.tar.gz

cd glibc-2.14

mkdir build

cd build

../configure --prefix=/opt/glibc-2.14

make -j4

sudo make install

export LD_LIBRARY_PATH=/opt/glibc-2.14/lib

    PS: Building process takes 2.5 hours on slow AWS.
