problem with upgrade

["Guy Markey" <guy_markey hotmail com>]

G'day,
I've just upgraded from redhat 7.2 to redhat 9. It seems to have created a 
problem with the c++ libs. A project I am writing (in c++) now wont link. It 
compiled and linked fine before the upgrade but now I just get about 500 
lines of linking errors. Can anyone sugest a reason why and how I might go 
about fixing it?
Thanks
Guy
