Compile error JointedCohesiveFrictionalPM

Asked by William Chevremont

Hi,

I've just updated the source code of yade using git pull and I get this compile error, comming from code added 2 days ago:

Hello William,

Which linux distribution are you running? Which compiler are you using (gcc --version)?

As Bruno mentions on yade-dev, your most recent build passes the buildbot [1] - so it may be a local problem. (I think Bruno's message [2] was not posted here as intended. He suggests you join yade-dev list serv [3] and send compiler questions there).

Although it seems unlikely - is it possible this has something to do with this unusual merge of master with itself [4]? Is that a merge into your local repository? Perhaps you are you working off a read-only clone? Do you have duplicated commits on your local machine? I can't quite figure out what is going on there, the "merge" seems to simply add commits that are already committed to the repository.

Cheers,

Robert

Hello

I have similar probleme with the latest mater branch (from 12/03/2018). I compile it on Debian 9 with GCC 6.3.0.
I had no trouble before (last version tested is the one dated of 21/02/2018).

I see that JointedCohesiveFrictionalPM.cpp JointedCohesiveFrictionalPM.cpp have been modified 6 day ago.
I try someting : I compile the new master (from 12/03/2018) with the old JointedCohesiveFrictionalPM.cpp JointedCohesiveFrictionalPM.cpp (from 21/02/2018 branch) and it works.

I hope it can helps.

Cheers
Thomas

Solved by adding #include <random> into JointedCohesiveFrictionalpm.hpp, Thanks Robert.

Can you help with this problem?
