What version of Deal.II is needed?

[jedbrown]

I tried with current 'master' (182e974ca9e2051625c4c19a160c3ad28285a3db) which is described as 9.0.0-pre but have template errors.

Hi Jed, I tried with the current master branch (1e5cdc3) on 64 bit Linux with gcc 5, deal.II version 9.0.0-pre, and it works on my machine. Can you post the compiler/system you are on as well as the errors you get? Did you check that make test of deal.II did work?

Hmm, I'm using gcc-6.2 on an Ubuntu node. Deal.II make test works. Error messages like this when building bp1:

Ah, now I see the problem. Your deal.II compilation does not include the p4est package which provides the parallel mesh partitioning algorithms. See the section on p4est on the front page / README.md or over here: http://dealii.org/developer/external-libs/p4est.html

I also pushed a new version of the CMakeLists.txt that actually checks this dependency.

Thanks.
