As the message says, this is due to sci-mathematics/cgal-6.0_beta1 requiring C++ 17: https://www.cgal.org/2024/06/21/cgal60-beta1/#general-changes. Downgrading to 5.6.1 solves the issue. So does patching openscad's c++std.pri like so: --- openscad-2021.01/c++std.pri.prog 2024-08-05 21:35:46.484782450 +0200 +++ openscad-2021.01/c++std.pri 2024-08-05 21:35:55.098192923 +0200 @@ -26,8 +26,8 @@ } c++std { - CONFIG += c++14 strict_c++ - message("Using C++14") + CONFIG += c++17 strict_c++ + message("Using C++17") *clang*: { # 3rd party libraries will probably violate this for a long time

patch in comment #2 works for me as well. Freecad then built correctly (can't tell how or where openscad is used by it and thus if it's all ok).

Dropping the patch from comment #2 into a file `/etc/portage/patches/media-gfx/openscad-2021.01-r5/0001-fix-c++std.patch` fixed the build for me. Thank you Micheal!

Document manifold USE-flag. Drop qt5 support. Bundle sanitizers-cmake as there is and likely never will be another consumer. Force CONFIG mode for FindBoost. Eigen3 is a header-only library and we do not have public headers, so it's DEPEND only. Add egl and glx USE-flags. Adjust ebuild style to fit the rest my ebuilds.

I have the exact same issue. I don't see any patches in the commit that closed this bug. Why it is closed (I was about to create the exact same bug ticket, as didn't find an open one on this topic)? I think the bug is still there: can't build with the mentioned error message: .[01m.[K/usr/include/CGAL/config.h:147:2:.[m.[K .[01;31m.[Kerror: .[m.[K#error "CGAL requires C++ 17"

Thank you for it.
Which version are you building? 20241114 should be built with C++17 as an upstream change.
