Build and Install GCC Suite from Scratch
#! /bin/bash
GCC_VERSION="5.2.0"
WORKDIR="$HOME/src/"
INSTALLDIR="/platform"
## NOTE: XCode must be installed (through App Store) and the following run to install command-line tools.
## THIS IS IMPORTANT! Among other things, it creates '/usr/include' and installs the system header files.
# xcode-select --install
# get the source code
cd $WORKDIR
wget http://www.netgull.com/gcc/releases/gcc-${GCC_VERSION}/gcc-${GCC_VERSION}.tar.bz2
tar -xf gcc-${GCC_VERSION}.tar.bz2
# download the prerequisites
cd gcc-${GCC_VERSION}
./contrib/download_prerequisites
# create the build directory
cd ..
mkdir gcc-build
cd gcc-build
# build
../gcc-${GCC_VERSION}/configure \
--prefix=${INSTALLDIR} \
--enable-shared \
--enable-threads=posix \
--enable-__cxa_atexit \
--enable-clocale=gnu \
--enable-languages=all \

&& make install
# Notes
#
# --enable-shared --enable-threads=posix --enable-__cxa_atexit:
# These parameters are required to build the C++ libraries to published standards.
#
# --enable-clocale=gnu:
# This parameter is a failsafe for incomplete locale data.
#
# --disable-multilib:
# This parameter ensures that files are created for the specific
# architecture of your computer.
# This will disable building 32-bit support on 64-bit systems where the
# 32 bit version of libc is not installed and you do not want to go
# through the trouble of building it. Diagnosis: "Compiler build fails
# with fatal error: gnu/stubs-32.h: No such file or directory"
#
# --with-system-zlib:
# Uses the system zlib instead of the bundled one. zlib is used for
# compressing and uncompressing GCC's intermediate language in LTO (Link
# Time Optimization) object files.
#
# --enable-languages=all
# --enable-languages=c,c++,fortran,go,objc,obj-c++:
# This command identifies which languages to build. You may modify this
# command to remove undesired language

Hi jeetsukumaran

Does your script work on windows OS ?

Markus

[root@localhost /home/admin/gcc-6.3.0]# ./contrib/download_prerequisites
./contrib/download_prerequisites: line 37: wget: command not found

[root@localhost /home/admin/wget-1.19]# ./configure
When I try to install wget, I get the following error:

Thanks.

@jithinjk from the log it looks like you need to install "wget" as well as "gcc" on the machine.

Nice utility, but GCC has started using .tar.gz now for releases instead of .tar.bz2 beginning with 6.4.0 so if the version number is changed (7.2.0 for example), the script will fail if the archive is not changed as well.
