[dune-pdelab] parameter pack expansion error in powergridfunctionspace.hh

[Eike Mueller]

Hi Dominic,


thanks. Steffen's post was from last year and based on icc 14.0. Intel claim that they would fix it, but I still get it with icc 15.0.


Let's see what Steffen says when he is back.


I can always fall back onto gcc.

Hey Eike,

I think the issue is with icc. What I found googling was this:

https://software.intel.com/en-us/forums/topic/501502

For some reason, the reporter is called "Steffen M.".....

So, I guess, the expert on the matter will return from holidays tomorrow.

Best,
Dominic

Dear DUNE PDELab,


I ran into a problem when compiling a simple finite volume test case. It falls over with the following error message:


In file included from /home/n/em459/scratch/git_workspace/dune/dune-pdelab/dune/pdelab/gridfunctionspace/gridfunctionspace.hh(32),

Should this be


"std::shared_ptr<Children...> children"


instead of


"std::shared_ptr<Children>... children"


in line 203 of powergridfunctionspace.hh? If I make this change it compiles fine.


I'm using the pdelab trunk and compile with the intel compiler (icpc (ICC) 15.0.0 20140723).


Thanks,


Eike
