[Trilinos-Users] Undefined reference to Epetra_Time when compiling

[Andris Freimanis]

Hello,

I'm trying to compile a small program that reads epetra matrices from 
matrix market file. And I'm getting this error:

I am pretty sure that I need to link additional libraries, but can't 
figure out which are missing. Do you have any suggestions?
