I thought the answer was "no".
Well if your sources are at /usr/src, then rarely, but there are leaks that have happend where /usr/include is refenced. > The line leading up to the error message is: > I am going to split this line up at -I > --- armv8_crypto_wrap.o --- > cc -target aarch64-unknown-freebsd12.0 --sysroot=/usr/obj/usr/src/arm64.aarch6 > 4/tmp -B/usr/obj/usr/src/arm64.aarch64/tmp/usr/bin -c -O3 -pipe -fno-strict-al > iasing -Werror -D_KERNEL -DKLD_MODULE -DHAVE_KERNEL_OPTION_HEADERS -include /u > sr/obj/usr/src/arm64.aarch64/sys/GENERIC-NODEBUG/opt_global.h -I. -I/usr/src/sys -fno-common -g -fPIC ^^^^^^^^^^^ Since your sources are /usr/src, this is fine, my problem is that I am compiling from /usr/src-topo, and I have patches, and these patches are NOT in /usr/src, but I have to put *some* of them in /usr/src to make my /usr/src-topo compile. SO something is broken, but I do not think that is what is effecting you. -I/usr/obj/usr/src/arm64.aarch64/sys/GENERIC-NODEBUG - > ffixed-x18 -ffreestanding -fwrapv -fstack-protector -gdwarf-2 -Wall -Wredundan > t-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-ar > ith -Winline -Wcast-qual -Wundef -Wno-pointer-sign -D__printf__=__freebsd_kpri > ntf__ -Wmissing-include-dirs -fdiagnostics-show-option -Wno-unknown-pragmas -W > no-error-tautological-compare -Wno-error-empty-body -Wno-error-parentheses-equ > ality -Wno-error-unused-function -Wno-error-pointer-sign -Wno-error-shift-nega > tive-value -Wno-error-address-of-packed-member -std=iso9899:1999 -Werror -m > arch=armv8-a+crypto /usr/src/sys/crypto/armv8/armv8_crypto_wrap.c > In file included from /usr/src/sys/crypto/armv8/armv8_crypto_wrap.c:46: > In file included from /usr/lib/clang/6.0.0/include/arm_neon.h:31: > > There's a "-I/usr/src/sys" in the fourth line, which in my case makes sense, > but where does the reference to /usr/lib/clang/.... come from, and is it > appropriate? Something for some reason included arm_neon.h? And I do not know why that was found at /usr/lib/clang/... Could it be something in that opt_global.h?

Your problem is not the same as mine. You are compiling from /usr/src, which hides the problem I am having. -- Rod Grimes rgri...@freebsd.org _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
