[Yade-dev] : Compilation on K/Ubuntu 18.04

2018-05-14 Thread Klaus Thoeni

Hi guys,

I remember a discussion with a CGAL problem to get yade ready for 18.04
LTS. From the discussion it looks that everything is solved. However, I
just did a fresh install of Kubuntu 18.04 and tried to compile the code
(latest trunk version).

cmake went fine but compilation didn't work as expected. I got an error
related to some CGAL commands used in DFNFlow.cpp:

/home/yade/YADE-git/trunk/pkg/pfv/DFNFlow.cpp: In member function ‘void
DFNFlowEngine::interpolateCrack(TemplateFlowEngine_DFNFlowEngineT >, DFNBoundingSphere>::Tesselation&,
TemplateFlowEngine_DFNFlowEngineT >,
DFNBoundingSphere>::Tesselation&)’:
/home/yade/YADE-git/trunk/pkg/pfv/DFNFlow.cpp:216:136: error: no match for
‘operator-’ (operand types are

CGAL::Alpha_shape_cell_base_3,
CGAL::Boolean_tag, CGAL::Boolean_tag >, CGAL::Sequential_tag>
> >::Point {aka CGAL::Weighted_point_3}’ and ‘const
CGAL::Origin’)
   if (newCell->info().fictious()==0) for (int k=0;k<4;k++) center = center
+ 0.25*(Tes.vertex(newCell->vertex(k)->info().id())->point()-CGAL::ORIGIN);

[Yade-dev] [Bug 1767601] Re: segmentation fault after erasing some particles

2018-05-14 Thread Jérôme Duriez

Hi,

I launched this script with Yade 2018-04-19.git-79b2edb.

I got the repeated output of "porosity X" with the porosity X-value soon
getting negativ, and then decreasing againt until ~ -1e100, then I
stopped manually the simulation.

I did not get any segmentation fault. Could you clarify the situation,
please ?

Title:
  segmentation fault after erasing some particles

Status in Yade:
  Incomplete

Bug description:
  Dear all,
  I built a simple script according to script-session1.py (B.Chareyre). I tried 
to erase some particles, it was done without any problem. but after finishing 
the simulation, as soon as  I tried to run more iterations, it showed 
segmentation fault and quit  yade.
  The length of O.bodies is similar to The one before erasing.(Does not change 
after erasing)
