https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D209652 Bug ID: 209652 Summary: graphics/embree: Fix build with libc++ 3.8.0 Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: danfe@FreeBSD.org Reporter: dim@FreeBSD.org Flags: maintainer-feedback?(danfe@FreeBSD.org) Assignee: danfe@FreeBSD.org Created attachment 170491 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D170491&action= =3Dedit Disable some overloaded math functions for libc++ 3.8.0 and higher During the exp-run in bug 208158, it was found that graphics/embree gives errors with libc++ 3.8.0 [1]: /wrkdirs/usr/ports/graphics/embree/work/embree-2.7.0/tutorials/common/tutor= ial/tutorial_device.cpp:270:39: error: call to 'abs' is ambiguous Vec3fa col =3D Vec3fa(min(1.f,.3f+.8f*abs(dot(Ng,normalize(ray.dir))))); ^~~ This is because embree defines its own version of a number of <cmath> functions, which cause the ambiguity. These functions are only declared in <cmath> for libc++ 3.8.0 and later, so fix it by disabling the custom funct= ions for those versions of libc++.
