[Dune] [#998] clang rejects specialisation with non-constant expression (Attachment added)

[Dune]

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY.

A new Flyspray task has been opened.  Details are below. 

User who did this - Elias Pipping (pipping) 

Attached to Project - Dune
Summary - clang rejects specialisation with non-constant expression
Task Type - Bug Report
Category - Grid
Status - Unconfirmed
Assigned To - 
Operating System - Unspecified / All
Severity - Low
Priority - Normal
Reported Version - SVN (pre2.2)
Due in Version - Undecided
Due Date - Undecided
Details - dune/grid/alugrid/common/geostorage.hh defines

static const int aluTriangle = ALU2DSPACE triangle;
static const int aluQuad     = ALU2DSPACE quadrilateral;
static const int aluTetra    = ALU3DSPACE tetra; 
static const int aluHexa     = ALU3DSPACE hexa;

and then specialises CreateGeometries w.r.t. that.

Clang is not amused:

error: non-type template
      argument depends on a template parameter of the partial specialization

I'm attaching a patch that makes the code compile with both g++ (tested with 4.4) and clang: The definitions are inlined (that's not an interface change because aluTriangle etc. were private).

One or more files have been attached.
