https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D220125 --- Comment #14 from Mark Millard <marklmi26-fbsd@yahoo.com> --- stdint.h was added to C in C99. It was intended to be the subset of the older inttypes.h that was suitable for freestanding environments. inttypes.h is defined to include stdint.h for C99 and later as I remember (or to behave as-if it had?). https://www.freebsd.org/cgi/man.cgi?build(7) is very explicit about what is supposed to be the case relative to kernel-toolchain use: kernel-toolchain Rebuild the tools needed for kernel compilation. Use this if you did not do a buildworld first. In other words: buildkernel is not intended to be self-contained/sufficient according to the build documentation but buildworld should not be required. Currently, overall, FreeBSD does not meet its own criteria for aarch64 rela= tive to kernel-toolchain . As far as I can tell the issue can be summarized relative to kernel-toolcha= in by saying that kernel-toolchain does not currently establish a (full) freestanding C99 environment (relative to the headers anyway) but building clang requires (at least) one of the missing items ( stdint.h ) for aarch64 contexts. In other words: I do not expect the blame would be with clang for this issue, but with FreeBSD's build environment. --=20 You are receiving this mail because: You are the assignee for the bug.=
