See FreeBSD bugzilla 220125: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220125 = <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220125>; You can hand patch the tree (similar to comment 3 but for the clang version in use). Later comments have notes about various places the file might go. If you can get buildworld to work, it will put stdint.h in the right = place. The places that you list are not the places the compiles actively look = in. See comment 9 for the difference between buildworld and kernel-toolchain for where the file is placed. kernel-toolchain does not do the right thing for arm_neon.h to work; arm-neon.h presumes that header, which is not normally part of a FreeBSD kernel build. Your report tells me that this is currently unresolved. =3D=3D=3D Mark Millard marklmi at yahoo.com ( markmi at dsl-only.net is going away in 2018-Feb, late)
