I downloaded
gpc-2.1-with-gcc.i686-pc-linux-gnu.tar.gz
because I thought that would be the sensible version, following the advice on the webpage (or so I thought). I expanded the tarball and tried to compile hellow.p with the following result:
$ gpc ~/pas/hellow.p /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/gpc1: /lib/libc.so.6: version `GLIBC_2.2' not found (required by /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.3/gpc1)
I have messed about with wrecking shared libraries before (Thank providence for sash, I say) so I took a copy of libc-2.2.5.so and symbolic-linked it to /lib/libc.so.6 and gave it a try (with sash running in a separate terminal so I could put the pieces back if things went wrong, as they did, giving another error message implying the need for further upgrades.) So I replaced the symbolic link /lib/libc.so.6 to libc-2.1.2.so and revived the system.
It will be evident that I am not a systems programmer. I would like to be able to upgrade gpc on my home machine and get everything working, but only if that won't break the touchier software such as vmware.
So I suggest not to play with the shared libs at all. Try to make GPC fit to them, not vice versa. If there's no Red Hat binary available (I don't know of a current one), you might want to try compiling it from sources.
If I can't do this I would like to put the old version of gpc back and do without the regex unit at home, but I don't know how to do this. Could I just expand the old tarball and get the old gpc back?
I guess so.
Is there a way to uninstall gpc?
Not automatically. Remove all the files from the tarball (a script may help). But if they overwrote files from the previous version, you need to re-install that one anyway. (If you must -- might be better to try and make a recent version work.)
