[Trilinos-Users] [EXTERNAL] Undefined reference to Epetra_Time when compiling

[Klinvex, Alicia Marie]

Hello Andris,

When you build Trilinos, a lot of information about how to build against Trilinos gets dumped to a file called Makefile.export.Trilinos.  You can import that file to gain access to variables such as $(Trilinos_CXX_COMPILER_FLAGS).

Here's an example of how to use Makefile.export.Trilinos: http://trilinos.sandia.gov/Export_Makefile_example.txt  Please let us know if it is still unclear.

Best wishes,
Alicia

Subject: [EXTERNAL] [Trilinos-Users] Undefined reference to Epetra_Time when compiling

Hello,

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

/usr/local/mpich/bin/mpicxx -O2 -std=c++11 -pedantic -ftrapv -Wall -Wno-long-long -Wno-deprecated -I/usr/local/trilinos/include -I/usr/local/mpich/include  -o main main.cpp -L/usr/local/trilinos/lib -lepetra -lepetraext -lblas -lteuchoscomm -lteuchoscore -lteuchosparameterlist -lkokkoscore -ldl

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