GCC 5.4.0
This guide assumes you are switched to su - . Please note that during the make step you may run into issues check the missing aclocal-1.15 section , this guide assumes you are using the eSG provided installation image.
Goal
Build GCC 5.4.0
Steps
Building Pre requisites
cd ~ mkdir buildgcc cd ~/buildgcc
Library Prerequisites
yum groupinstall "Development tools" yum install glibc-devel.i686 glibc.i686 texinfo
EXPORTS used to set versions
You can change the values here to change the compiled version.

Copy downloaded libraries in GCC directory
cd gcc-${GCC_VERSION} cp -R ../mpc-${MPC_VERSION} mpc cp -R ../mpfr-${MPFR_VERSION} mpfr cp -R ../gmp-${GMP_VERSION} gmp cp -R ../isl-${ISL_VERSION} isl cp -R ../cloog-${CLOOG_VERSION} cloog
Hardcoded autoconf
Since autoconf is hardcoded you need to update to your own version Find your version using:
rpm -qa | grep autoconfexample: autoconf-2.69-11.el7.noarch, thus you have version 2.69 .
Find the following line in
m4_ifndef([_GCC_AUTOCONF_VERSION], [m4_define([_GCC_AUTOCONF_VERSION], [2.69])])and change the version to your own
missing aclocal-1.15
Since your version of aclocal may be different you should autoreconf using:
autoreconf -ivf autoreconf -ivf mpfr/ autoreconf -ivf isl/ autoreconf -ivf cloog/
Configure GCC
./configure --prefix=/opt/gcc-${GCC_VERSION} --enable-multilib --with-system-zlib
Make GCC
Warning: This process will take quite a few hours, make sure the build is started in a multiplexer (eg tmux)
make
Install GCC
make installThis will install GCC in the path you set in configure with –prefix=
