Bug#876467: freefem++: load of tetgen for 3d failed

[Stefan K.]

Package: freefem++
Version: 3.47+dfsg1-2
Severity: normal

Dear Maintainer,

loading of tetgen which is documented for 3D meshes fails, eg.:

=======================================================================
$ FreeFem++ /usr/share/doc/freefem++/examples/examples++-3d/cylinder.edp
-- FreeFem++ v  3.470000 (date 2017-09-10)
 Load: lg_fem lg_mesh lg_mesh3 eigenvalue
    1 : load "msh3"
    2 : load "tetgen"
load error : tetgen
         fail :
 dlerror : /usr/lib/freefem++/tetgen.so: cannot open shared object file: No such file or directory
list  prefix: './' '/usr/lib/freefem++/' list  suffix : '' , '.so'

 Error line number 2, in file /usr/share/doc/freefem++/examples/examples++-3d/cylinder.edp, before  token tetgen
Error load
  current line = 2
Compile error : Error load
        line number :2, tetgen
error Compile error : Error load
        line number :2, tetgen
 code = 1 mpirank: 0
=======================================================================

This happens even if the package tetgen is installed.

Kind regards,
Stefan K.
