View Full Version : Libc5 - Compatibility problems

6th September 2007, 08:18 AM
Hi all,

I've got a really big problem... I've got an application which was developped in the 90's.
So i only have the program and NOT the sources. So i'm not able to recompile it. The program works with library classes like libc5 instead of libc6 etc.

How can i install both libc5 and libc6 on my computer without messing up my OS?
A buddy of me said i could use the ldconfig command. But the man pages don't make clear what i have to do...

So can someone give me some explanation to let it work the old program work under FC or even under RHEL(CentOS)?

Looks like it is not that clear... 'cos many views no answer. So I rephrash...
The old application uses libc4 which supports "a.out" ... now I'm using Fedora Core 7 and CentOS 5 and i want to put the libc4 class together with glibc /libc6. Is that possible? And how do you do that? I already tried a lot of things..but i'm getting desperate...

They have compatibility libraries for libstdc++ but the one you want is libc and that is in the glibc package and I don't see a compat version for that. Apparently having libc.so.5 along with libc.so.6 would cause problems.
