Hi Dr. Bangerth, Thank you for your reply. You are right. When I checked for compilers I have two versions of each compilers. I don't know why that is....I do have petsc installed and I think that might have used different compilers. Is there a way to tell dealii to choose compilers?
I have the following: $ dpkg --list | grep compiler ii g++ 4:5.3.1-1ubuntu1 amd64 GNU C++ compiler ii g++-5 5.4.0-6ubuntu1~16.04.4 amd64 GNU C++ compiler ii gcc 4:5.3.1-1ubuntu1 amd64 GNU C compiler ii gcc-5 5.4.0-6ubuntu1~16.04.4 amd64 GNU C compiler ii gfortran 4:5.3.1-1ubuntu1 amd64 GNU Fortran 95 compiler ii gfortran-5 5.4.0-6ubuntu1~16.04.4 amd64 GNU Fortran compiler ii hardening-includes 2.7ubuntu2 all Makefile for enabling compiler flags for security hardening ii libllvm3.6v5:amd64 1:3.6.2-3ubuntu2 amd64 Modular compiler and toolchain technologies, runtime library ii libllvm3.8:amd64 1:3.8-2ubuntu4 amd64 Modular compiler and toolchain technologies, runtime library ii libllvm3.8:i386 1:3.8-2ubuntu4 i386 Modular compiler and toolchain technologies, runtime library ii libprotoc9v5:amd64 2.6.1-1.3 amd64 protocol buffers compiler library ii libxkbcommon0:amd64 0.5.0-1ubuntu2 amd64 library interface to the XKB compiler - shared library ii protobuf-compiler 2.6.1-1.3 amd64 compiler for protocol buffer definition files Please advise on what to do next. I really appreciate your help! Thanks!
