Error(s) that match a know pattern in addition to what has been reported in the summary:

/usr/include/CGAL/config.h:147:2: error: #error "CGAL requires C++ 17"

Comment 4 Fernando B. Nascimento 2025-01-03 18:47:17 UTC

I beleave that media-gfx/openscad-2021.01-r5 is incompatible with sci-mathematics/cgal-6.0 or newer. Actually any openscad-2021.01.

#### Why:

Build log says (see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117146 referenced in comment #3):

    /usr/include/CGAL/config.h:147:2: error: #error "CGAL requires C++ 17"

And the following line is present on https://github.com/openscad/openscad/releases/tag/openscad-2021.01

    Switch to C++14 and allow usage of header-only CGAL

I compiled openscad by masking cgal 6.0 and compiling cgal and openscad:

#### Commands and outputs:

# echo "=sci-mathematics/cgal-6.0" >> /etc/portage/package.mask/openscad-cgal
# emerge -1vq sci-mathematics/cgal && emerge -1vq openscad

#### Sugested fix thatI don't know the correct way of doing:

ebuild depend on <sci-mathematics/cgal-6

Confirmed solution
After I did
emerge -1a =sci-mathematics/cgal-5.6.1
the
emerge -a media-gfx/openscad
completed successfully.
Thank you to Fernando B. Nascimento!
