Is it really possible to install gcc using prerequisites are installed in non standard directories.

[Allan Kamau <kamauallan at gmail dot com>]

I have been struggling for two days to get gcc to compile and install
in a specific directory without success. If there is a HOWTO for this
please point me to it.


I have installed mpc-0.8.1, mpfr-2.4.2 and gmp-4.3.2 to specific
directories as follows

mpc-0.8.1=”/home/somebody/apps/gcc/mpc-0.8.1”
mpfr-2.4.2=”/home/somebody/apps/gcc/mpfr-2.4.2”
gmp-4.3.2=”/home/somebody/apps/gcc/gmp-4.3.2”

I am compiling gcc-4.8.0 using the following options.

date;time ~/apps/src/gcc-4.8.0/configure
--with-mpc=/home/somebody/apps/gcc/mpc-0.8.1
--with-mpfr=/home/somebody/apps/gcc/mpfr-2.4.2
--with-gmp=/home/somebody/apps/gcc/gmp-4.3.2
--prefix=/home/somebody/apps/gcc/gcc-4.8.0
--with-gmp-lib=/home/somebody/apps/gcc/gmp-4.3.2/lib
--with-gmp-include=/home/somebody/apps/gcc/gmp-4.3.2/include
--with-mpfr-lib=/home/somebody/apps/gcc/mpfr-2.4.2/lib
--with-mpfr-include=/home/somebody/apps/gcc/mpfr-2.4.2/include
--with-mpc-lib=/home/somebody/apps/gcc/mpc-0.8.1/lib
--with-mpc-include=/home/somebody/apps/gcc/mpc-0.8.1/include;date;
