Compilation error in dealii development version (version 9.1.0-pre, shortrev 7537ea7) using intel/18.0.2 compiler

[Sambit Das]

Dear all,

I am trying to compile the latest development version of dealii (version 9.1.0-pre, shortrev 7537ea7) using intel/18.0.2, intelmpi and cmake/3.10.2.

During compilation I get the following error:

/work/05316/dsambit/publicSharedSoftware/dealiiDevLatest/dealii/source/multigrid/mg_transfer_matrix_free.cc(356): error: expression must have a constant value

    constexpr unsigned int three_to_dim = Utilities::pow(3, dim);

I have attached the detailed.log file. 

 I am wondering if I am missing any compilation flags, or whether this is an intel compiler issue.

Thanks a lot in advance,

Best,

Sambit
