Thank you very much for help Janek.
I confirm that I could compile trunk on ubuntu18 with CGAL, without special steps (not even dpkg, just cmake+make without options). For DEM-PFV-check.py the problem is with the cholmod solver. I'll try and fix that.


@Robert, you mentioned that by-passing the eigen interface to use cholmod directly solved issues on your side IIRC. Could you give more hints about that, do you have some candidate code for commit?

Cheers

Bruno

OK, so I did the initial commit for cgal 4.11, the most importatnt stuff is in the commit message. I will repeat it here in short:

1.  maybe the #ifdefs that I added in lib/triangulation/RegularTriangulation.h are not necessary?

2. the ALPHASHAPES changes inlib/triangulation/Tesselation.h are not related to cgal, but I couldn't compile without this.

3. In checkPolyhedraCrush.py this python line freezes:
     O.run(250, True); checkForcesBodies(25.44893, 4)

Moreover:
4. with this patch yade is compiling successfully with cgal 4.9 and 4.11.

5. regardless of cgal version (with 4.9 and 4.11) I have this error in DEM-PFV-check.py:

  running:  DEM-PFV-check.py
  DEM-PFV: unbalanced Qin vs. Qout ( -0.00279199571618  vs. 0.0 )

Since it does not depend on cgal version, it must be some other library that I have on my workstation. I have here installed devuan ascii, and I only backported cgal 4.11 from devuan ceres. All other libraries are at their default devuan ascii version.

6. Also  yade version is clean, right from github :) Just to make it all clear. However I could not compile yade just by doing the usual

  cd .. ; mkdir build ; cd build
  cmake -DCMAKE_INSTALL_PREFIX=../install ../trunk -DDEBUG=1 -DCHUNKSIZE=5
  time nice -n 20 make install -j 20 ; xmessage "\nFinished\n"

I had some boost errors related to the C++11 declytype support, eg. as discussed in: http://www.boost.org/doc/libs/1_66_0/libs/utility/utility.htm At first I was worried that g++ 6.3 is too old. However I found out that I can compile yade 2018-02 if I copy the ./debian/ directory from yade 2017-01 and do:

   time dpkg-buildpackage -rfakeroot -b -j30

So it must not be related to compiler version, but rather to compiler flags. And Anton fixed this in debian/ build rules, while my command could not make it correctly. I didn't figure this out yet. Last night I was simply building yade 2018-02 with debian/ from yade 2017-01 :)

best regards
Janek

            Hi Anton and Bruno,

            I am glad that I can help, and use this opportunity to get
            back in track
            ;) So I will do this entire Saturday after I get back home
            on friday night.

            Should I work on latest yade trunk?

            BTW: I'm writing this from an airport ;)

            Best regards,
            Janek

                Hi Bruno,

                CGAL_ 4.11 is the only version now for Debian
                (testing) [1]
                and upcoming Ubuntu 18.04 [2]. The shipped Yade does
                not support CGAL due to compilation problems.

                I am preparing the new Yade upload, but we have a chance
                to patch the Yade within the next two weeks or prepare
                the 2018.02b release with CGAL-support and upload it.

                    Hi Anton,
                    Thank you very much.
                    I'm not so sure what we are speaking about here.
                    Yade 2018.02a is the candidate source code for
                    producing a binary
                    yade-stable in Ubuntu 18.04, correct (approximately)?
                    If yes, can we build yade-stable with CGAL at the
                    moment?
                    Bruno

                        I think there is a chance to get it pushed
                        into Debian->Ubuntu.

                                Saturday,
                                if my last patches didn't work for you?



                            I did not test it yet I'm afraid. :-/
                            It sounds like a critical issue for a
                            18.04 release. Is it?
                            Would that mean to skip the whole CGAL
                            related code in the binary
                            release?
                            I'll go back to this asap, thanks for pinging.
