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 \
&& 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
