Kdevelop 2.0 cant compile

Tue Sep 11 07:40:02 BST 2001

Ok so i did BUT....
i discovered that a program compiled with gcc 2.95.2.1 CANT find simbols in a 
shared library compiled with 3.0.x!
i get tons of "unresolved wymbol Qt_xxxx::Qt_xxxxx()"
when i try to compile (better say to link) with 2.95.2.1 and please note qt 
is build shared with 3.0.1 and the same linking works with 3.0.1 (but of 
course i get error in compiling, sigh!)
