Hi all,

until yesterday I was able to build my CGAL code (on macOSX using the script provided by CGAL library), but today I'm not anymore even if I didn't changed nothing but only restarting my PC. Is there maybe an automatic updating issue of my OS?

Anyhow the problem is the following:

maybe the boost library is not found properly ... after running the CGAL script, the standard output result showed to me that Boost was found but after running make I obtained a lot of errors ... here there are the few first lines. I tried to find a solution on the web but I was not able, do you have any idea? I need to reinstall boost?
