Re: [Gems-users] GCC compatibility

[Byn Choi <bynchoi1@xxxxxxxxxxxx>]

You are not locked into using old ubuntu release just to use older  
version of gcc. Different releases of gcc can coexist in a system, you  
can simply drop one in in your local directory. Simply configure GEMS  
to use the older gcc, look at $GEMS/common/Makefile.common.
Personally, my system gcc is 4.1.2 while I use locally installed gcc  
3.4.6 for GEMS. Dynamically linked libraries do not need to be  
compiled using the same version of gcc as the GEMS modules.
