Re: [Libmesh-users] missing libMesh symbols

[Kirk, B. (JSC-EG311) <ben...@na...>]

Can you report the debug compiler flags that are being used?  We attach libstdc++ internal debugging flags where supported, and this could be causing problems in your case if you are linking to an application that doesn't use our flags. Note this is only for gcc compilers. 

Do opt/devel methods work ok?

Also, it wasn't clear to me - is the linking issue on Blue Waters or locally? 

Thanks,
