Before we get started we need to do some dependency work :(

1. Download the following applications a directory of your choice. Lets name it, $HOME/gcc-build. Extract the applications into gcc-build.

GCC - http://gcc.gnu.org/gcc-4.8/
GMP - http://gmplib.org
MPFR - http://www.mpfr.org
MPC - http://www.multiprecision.org
Binutils - http://www.gnu.org/software/binutils

2. Create another directory called " contrib " within the gcc-build directory, ending up with $HOME/gcc-build/contrib

3. Extract the applications you downloaded into the  $HOME/gcc-build directory. Consider this to be our staging area. Follow the instructions in the order they are listed in as its dependency based. For example, MPFR is dependent on GMP being compiled and installed. Latest versions.

GMP:
  • Extract with tar xfvz gmp.tar.gz
  • Create $HOME/gcc-build/contrib/gmp
  • Change into the directory and compile with ./configure --prefix=$HOME/gcc-build/contrib/gmp
  • make && make install
MPFR:
  • Extract with tar xfvz mpfr.tar.gz
  • Create $HOME/gcc-build/contrib/mpfr
  • Change into the directory and compile with ./configure --prefix=$HOME/gcc-build/contrib/mpfr --with-gmp-build=<directory in which the source is in, the extracted directory and not the binary directory>
MPC:
  • Extract with tar xfvz mpc.tar.gz
  • Create $HOME/gcc-build/contrib/mpc
  • Change into the directory and compile with ./configure --prefix=$HOME/gcc-build/contrib/mpc --with-gmp=$HOME/gcc-build/contrib/gmp --with-mpfr=$HOME/gcc-build/contrib/mpfr
  • make && make install
BinUtils:
  • Extract with bunzip binutils && tar xfv binutils.tar
  • Create $HOME/gcc-build/contrib/binutils
  • Change into the directory and compile with ./configure --prefix=$HOME/gcc-build/contrib/binutils
  • make && make install
  • make target_header_dir=$HOME/gcc-build/binutils/include -C libiberty
Library and Path location updates
Now that we have completed all the dependency requirements its important to update the library paths and system paths. Add the following below to $HOME/.bashrc ( User specific functions).

LD_LIBRARY_PATH=$HOME/gcc-build/contrib/mpc/lib:$HOME/contrib/gcc-build/mpfr/lib:$HOME/gcc-build/contrib/gmp/lib:$HOME/gcc-build/contrib/binutils/lib:$LD_LIBRARY_PATH
COMPILE_OF=$HOME/gcc-build/contrib/binutils/bin
PATH=$COMPILE_OF:$PATH

Logout and login to refresh the environment.

Compile GCC
  • Earlier you downloaded the latest version of GCC from a mirror site into $HOME/gcc-build/ and extracted the contents in there.
  • Create a directory $HOME/gcc-build/build and change directory into $HOME/gcc-build/build. Notice that we are NOT executing the "./configure" script from within the extracted directory but rather from a build directory. Its extremely important to adhere to this rule.
  • cd $HOME/gcc-build/build
  • "../gcc-4.8.1/configure --prefix=$HOME/gcc-build/contrib/gcc/ --enable-languages=c,c++ --with-gmp=$HOME/gcc-build/contrib/gmp --with-mpc=$HOME/gcc-build/contrib/mpc/ --with-mpfr=$HOME/gcc-build/contrib/mpfr/"  ( NB: notice the importance of the two periods before the configure script )
  • make -j 4 ( This assumes that you would like the compile of GCC to consume 4 CPU processors.
  • make install
  • make clean ( This will erase all the intermediate files )
  • $HOME/gcc-build/contrib/gcc/bin/gcc –version should give show the correct version.
 

Configure Modules which is a shell environment manager. Great for managing libraries and various versions of software. I have attached the template for GCC 4.8 which can be placed into the "modulefiles" directory.
