CGAL users discussion list

[Filippo <>]

Hello

I am trying to link CGAL to my software. I cannot compile neither CGAL 5.2 (git branch 5.2.x-branch) nor CGAL 5.1 (git branch 5.1.x-branch) with Boost 1.75 and mpicc/mpiccx (openmpi/4.0.2 and gcc-4.8.5). My software exploits libmesh to compute mesh intersection via CGAL.

The error I get concerns the placeholders and it is apparently a current issue with CGAL/Boost interfacing

$locinst/cgal/include/CGAL/convex_hull_3.h: In function 'typename std::__cxx11::list<Point>::iterator CGAL::Convex_hull_3::internal::farthest_outside_point(Face_handle, std::__cxx11::list<Point>&, const Traits&)':

I configure CGAL via the following command:

cmake -DCMAKE_INSTALL_PREFIX=${locinst}/cgal -DCMAKE_BUILD_TYPE=Release -DGMP_LIBRARIES=${locinst}/gmp-6.1.2/lib/libgmp.so -DMPFR_LIBRARIES=${locinst}/mpfr-3.1.6/lib/libmpfr.so -DGMP_INCLUDE_DIR=${locinst}/gmp-6.1.2/include -DMPFR_INCLUDE_DIR=${locinst}/mpfr-3.1.6-dw2bdrou2piprxsnfj3qsbroml3ych6v/include -DCGAL_HEADER_ONLY=OFF $srclib/cgal

Boost 1.75 is configured with mpicc.

Finally, the libmesh installation is based on petsc 3.13.1 with mpicc/mpicxx.

Is there any workaround for this? Should I switch to gnu++14 dialect in my software or reinstall gcc with gnu++14 dialect support?

Thanks
