[Trilinos-Users] NOX Undefined Reference linking issues with gcc 4.1.2

Hey Everybody,

I get tons of undefined reference to typeinfo ... type linking errors 
when using NOX with gcc 4.1.2 that aren't present when compiling with 
gcc 4.5.1.  I've quickly looked at the NOX source for say 
NOX::Abstract::Vector to see if the abstract base classes had undefined 
non-pure virtual functions but everything looked good.  I've tried 
explicitly including some of the abstract base class headers but to no 
avail.  Anybody know what the issue is exactly?  How I can fix it to 
compile under 4.1.2?  What is different between 4.5.1 and 4.1.2 that 
lets that link?
