Description Dima Pasechnik 2022-03-31 21:43:53 UTC

attempts to use tbb/CGAL's parallel facilities fail, as CGAL's version is outdated. In particular, in the current tbb the header tbb/parallel_do.h, used by CGAL 5.2, was removed. More details in https://github.com/CGAL/cgal/issues/6168

Reproducible: Always

Steps to Reproduce:
1. install current CGAL and tbb
2. try compiling mesh_implicit_sphere.cpp CGAL example (https://doc.cgal.org/latest/Mesh_3/Mesh_3_2mesh_implicit_sphere_8cpp-example.html) 

Actual Results:  
see "fatal error: tbb/parallel_do.h: No such file or directory"

Expected Results:  
should work

use a CGAL version with the bug fixed, e.g. the current (5.4), or
