Hmmm. I wonder what would happen if you did a google search for:
"libstdc++.so.5" fedora 4 rpm
?
Perhaps the very first hit on such a search would lead you to a place where you could download the right compatibility file? I don't know, you'll have to check...
Hahaha, yes, it does. The question is, why couldn't you figure this out? The thought process is pretty simple:
1) I need libstdc++.so.5
2) I need it for Fedora 4
3) rpms are easy to install
4) so, enter those search terms into google
Think, man! Google is your friend!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Once you install this rpm, that should take care of everything.
