Including "libmesh/node.h" got rid of the error when using make example-opt for my modified example. I was wondering what I do to view the output of the C program though. I would think I should run example-opt. When I did this I got the output: Usage: /opt/libmesh-1.0.0-rc1/examples/eigenproblems/ eigenproblems_ex2/.libs/lt-example-opt -n <number of eigen values> Stack frames: 5 0: libMesh::print_trace(std::ostream&) 1: libMesh::MacroFunctions::report_error(char const*, int, char const*, char const*) 2: /opt/libmesh-1.0.0-rc1/examples/eigenproblems/eigenproblems_ex2/.libs/lt-example-opt() [0x40c17e] 3: __libc_start_main 4: /opt/libmesh-1.0.0-rc1/examples/eigenproblems/eigenproblems_ex2/.libs/lt-example-opt() [0x40c29d] [0] eigenproblems_ex2.C, line 45, compiled Aug 17 2016 at 15:52:06 application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0
