[Trilinos-Users] make problem: teuchos link to mpi

[Salinger, Andrew]

Hi Wilbert,

I have 2 guesses:
(1) Even though you enable MPI, you might be
overriding the compiler choice with explicitly
picking the compilers to be $F77, $CC, $CXX.
You can echo these variables to make sure they
are  mpicc and not gcc.

(2) You may need to add the MPI library directory
to your "LD_LIBRARY_PATH" environment variable.
This is typically done in  .bashrc or .cshrc files.

If this doesn't help, send us all the screen
output from the cmake and make commands.

Subject: [Trilinos-Users] make problem: teuchos link to mpi

Hi,

Hopefully this is a trivial problem: I'm trying to build Trilinos 10.0.1 on a x86_64 linux platform, but it seems that Teuchos has trouble linking to MPI. I get errors like:

/usr/projects/climate/wilbert/Libraries/TRILINOS/trilinos-10.0.1-Source/packages/teuchos/src/Teuchos_GlobalMPISession.cpp:173:
undefined reference to `MPI_Comm_size'

Below is my cmake line, where I explicitly specify the MPI directory (and I verified that it includes an include directory containing mpi.h), and I explicitly set Teuchos_ENABLE_MPI and TPL_ENABLE_MPI.

Am I overlooking something?

Thanks!
