Problem with gfortran lib on Ubuntu 16.04

[SvensenSeven]

I have the similar problem as #379 .
How this issue could be solved ?

I've checked the libraries. lgfortran.a is installed as well as lgfortran.so

Hi Svensen. I solved this problem.

1. Please make sure that you have installed the right version of gfortran and g++ corresponding to the gcc (use "gfortran -v" to check the version). If you finish the installation, please cd to the "/usr/lib" to check the existence of libgfortran.a.
2. And check the file "Elemental/cmake/external_projects/ElMath/OpenBLAS.cmake" in thirdparty folder. Make sure that your GFORTRAN_PATHS is correct (x86_64-linux-gnu or i386-linux-gnu, 4.8 or 4.9 or 5). If not, please modify the file.
3. Install openmpi (download openmpi-2.1.1, libopenmpi-dev) and mpich.
4. It's better to install the code in 64bit ubuntu system
