gcc-build-vars.sh

#!/bin/bash
##
##  Script: gcc-build-vars.sh
##
##  This script sets configuration and build variables that are used by
##  all the other scripts.  It is intended to be called by other scripts.
##  It assumes that TOP_DIR has been defined appropriately by the caller,
##  and that it is being sourced by the calling script.
##
##- Customize this variable to specify the version of GCC that you want
##  to download and build (replace the 'X' with the minor version number).
##
export GCC_VERSION=12.X.0

##- Customize this variable to specify where this version of GCC will be
##  installed.
##
export GCC_INSTALL_PREFIX=/usr/local/gcc/$GCC_VERSION

##- Customize this variable to specify where to install the scripts that
##  set various important environment variables for using this custom GCC
##	build in day-to-day work.
##
export GCC_INSTALL_SCRIPTS_PREFIX=/usr/local/bin

##- Customize this variable to specify the installation's time stamp.
##
export GCC_TIME_STAMP=202208041000

##- Customize these variables if you want to change the arguments passed
##  to 'make' that specify the number of jobs/processes used to build and
##  test GCC, respectively.
##
export GCC_BUILD_JOBS_ARG='-j16'
export GCC_TEST_JOBS_ARG='-j8'

##- Set this variable to YES if you want to embed the assember and linker
##  from a custom version of GNU Binutils (specified below) into the GCC
##  installation.  If you just want to use the system's assembler and linker,
##  then undefine this variable or set its value to "NO".
##
export GCC_USE_CUSTOM_BINUTILS='NO'

##- Set this variable to YES if you want to perform a profiled booststrap
##  installation.  This option performs profiled builds and then link-time 
##  optimiztion during the build process, which can improve the run-time
##  performance of the compiler itself.  If you don't care, or wish to just
##  do a regular build, then undefine this variable or set its value to "NO".
##  If you choose "YES", be aware that this option can substantially increase 
##  the compiler's build time, perhaps doubling it or more.
##
export GCC_USE_PROFILED_BOOTSTRAP='NO'

##------------------------------------------------------------------------------
##      Maybe change below this line, if you have a good reason.
##------------------------------------------------------------------------------
##
##- Customize variable this to name the installation; the custom name is
##  displayed when a user invokes gcc/g++ with the -v or --version flags.
##
export GCC_PKG_NAME='KEWB Computing Build'

##- Customize this variable to define the middle substring of the GCC build
##  triple.
##
export GCC_CUSTOM_BUILD_STR=kewb

##- Customize this variable if you want the gcc/g++ executables to be
##  built with a suffix in their names (e.g., gccfoo/g++foo). In general,
##  this is best left undefined.
##
export GCC_EXE_SUFFIX=

##- These variables define the versions of binutils, GMP, MPC, and MPFR
##  used to build GCC.
##
export BU_VERSION=2.37
export GMP_VERSION=6.1.2
export MPC_VERSION=1.1.0
export MPFR_VERSION=3.1.6

##      Do not change below this line!
