   3 # Simple script to build GCC natively including its prerequisites.
   4 #
   5 # Depending on your needs you maybe able to speed up the GCC build:
   6 #
   7 # (a) Do not build a c++ compiler
   8 #     c++ is only needed for "make check" and running regression tests
   9 #     --> choose  LANGUEGES=c   below
  10 # (b) Do not build a compiler that can produce 32-bit executables
  11 #     on a 64-bit platform
  12 #     --> choose  MULTILIB=--disable-multilib   below
  13 #
  14 # Define the following 5 variables:
  15
  16 BUILD_DIR=/tmp/build-gcc
  17 INSTALL_DIR=/tmp/install
  18
  19 GCC_VERSION=5.1.0
  20 LANGUAGES=c,c++
  21 MULTILIB=
  22 #LANGUAGES=c
