Installing GCC/G77: Example


The following is an example of how to: Configure, build and install gcc/g77 in the /usr directory.

Ftp the source to the current directory (Need at least 200MB space available):
% ftp ftp.gnu.org
cd pub/gnu/gcc
bin
get gcc-2.95.2.tar.gz
quit

Unzip and untar the source in the current directory:
% tar xvfz gcc-2.95.2.tar.gz

Modify the libI77/fio.h fortran include file to allow access to 10000 unit numbers :
% vi gcc-2.95.2/libf2c/libI77/fio.h
Replace line:
#define MXUNIT 100
With line:
#define MXUNIT 10000

Make the build directory and run configure:
% mkdir gcc-2.95.2_obj
% cd gcc-2.95.2_obj
% ../gcc-2.95.2/configure --prefix /usr

Build GCC/G77
% make bootstrap

Install GCC/G77
% make install

Your done!!!
