First insert the redhat cdrom, and reinstall gcc + development,
so that it is in working condition. i.e. : rpm -i --force *gcc*
Get the following files from the CDROM which contains gnu stuff :
-rw-rw-r-- 1 stock users 1010463 Sep 13 16:45 g77-0.5.18.tar.gz
-rw-rw-r-- 1 stock users 7132291 Sep 13 16:55
gcc-2.7.2.1.tar.gz
And perform literally the following commands :
sh[ 1]# `cd /usr/src'
sh[ 2]# `gunzip -c < /usr/FSF/gcc-2.7.2.1.tar.gz | tar xf -'
[Might say "Broken pipe"...that is normal on some systems.]
sh[ 3]# `gunzip -c < /usr/FSF/g77-0.5.18.tar.gz | tar xf -'
["Broken pipe" again possible.]
sh[ 4]# `ln -s gcc-2.7.2.1 gcc'
sh[ 5]# `ln -s g77-0.5.18 g77'
sh[ 6]# `mv -i g77/* gcc'
[No questions should be asked by mv here; or, you made a mistake.]
sh[ 7]# `patch -p1 -V t -d gcc-2.7.2.1 <
gcc-2.7.2.1/f/gbe/2.7.2.diff'
[Unless patch complains about rejected patches, this step worked.]
sh[ 8]# `cd gcc'
sh[ 9]# `touch f77-install-ok'
[Do not do the above if your system already has an f77
command, unless you've checked that overwriting it
is okay.]
sh[10]# `touch f2c-install-ok'
[Do not do the above if your system already has an f2c
command, unless you've checked that overwriting it
is okay. Else, `touch f2c-exists-ok'.]
sh[11]# `./configure --prefix=/usr'
[Do not do the above if gcc is not installed in /usr/bin.
You might need a different `--prefix=...', as
described below.]
sh[12]# `make bootstrap'
[This takes a long time, and is where most problems occur.]
sh[13]# `rm -fr stage1'
sh[14]# `make -k install'
[The actual installation.]
sh[15]# `g77 -v'
[Verify that g77 is installed, obtain version info.]
sh[16]#
Goodluck. On My dual PPro 200 system this was done in 15 minutes.
