https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D172946 John Baldwin <jhb@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jhb@FreeBSD.org --- Comment #5 from John Baldwin <jhb@FreeBSD.org> --- We have never installed all of the headers. /usr/include/machine is only f= or the current architecture and the header files from other architectures have never been installed. There is no, and never has been, /usr/include/alpha = on any FreeBSD/i386 system for example. /usr/include/x86 is a special case for amd64 and i386 to allow those two arches to share headers so that `cc -m 32` works. The same for /usr/include/arm for armv7 and aarch64. Currently, cross-compilation requires having a sysroot built for the architecture which includes the MD headers in /usr/include/machine and the architecture-specific libraries in /usr/lib. We don't install armv7 librar= ies as part of an amd64 world. Instead, for cross-compilation an armv7 sysroot= has to be created either via 'make installworld' to a DESTDIR or extracting base.txz, etc. and then using the --sysroot argument to cc and ld (and `set sysroot` in gdb). If we want to fix this properly, we just need to add BSD.include.${MACHINE_ARCH}.dist files that contain architecture-specific directories. The existing entry for /usr/include/machine/pc should move in= to the i386/amd64 file (and those two arches can probably just share a BSD.include.x86.dist if we support an optional BSD.include.${MACHINE_CPUARCH}.dist file). We would only use the matching = MD tree files when creating directories and install the matching tree files in /etc/mtree. --=20 You are receiving this mail because: You are the assignee for the bug.=
