https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233735 --- Comment #11 from Mark Millard <marklmi26-fbsd@yahoo.com> --- (In reply to Mark Millard from comment #10) [Back to system-clang.] clang may not report its search path sequence but truss reports the following involving "machine": 52747: fstatat(AT_FDCWD,"./machine",0xffffffff9190,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/13_0R-src/sys/machine",0xffffffff9190,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/13_0R-src/sys/contrib/ck/include/machine",0xffffffff9190,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/13_0R-src/sys/contrib/libfdt/machine",0xffffffff9190,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/13_0R-src/sys/contrib/device-tree/include/machine",0xffffffff9190,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/13_0R-src/sys/sys/machine",0xffffffff9ab0,0x0) ERR#2 'No such file or directory' It is not even trying the sysroot as a path prefix for the include involving "machine". The usage involving "BUILDs" was: # grep BUILDs truss.txt 52747: fstatat(AT_FDCWD,"/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/local/cuda",0xffffffffc430,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/local/cuda-8.0",0xffffffffc430,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/local/cuda-7.5",0xffffffffc430,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/local/cuda-7.0",0xffffffffc430,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/opt/rocm",0xffffffffc4e0,0x0) ERR#2 'No such file or directory' 52747: fstatat(AT_FDCWD,"/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/sys/GENERIC-NODBG-CA7",{ mode=drwxr-xr-x ,inode=6,size=3187,blksize=16384 },0x0) = 0 (0x0) 52747: __realpathat(AT_FDCWD,"./opt_global.h","/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/sys/GENERIC-NODBG-CA7/opt_global.h",1024,0) = 0 (0x0) There is no evidence of any attempted use of sysroot has a general include path prefix. A "cc -###" with the other parameters as in the .o.meta does report: "-isysroot" "/usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp" So the following would seem to apply if otherwise /usr/include/ usage would be expected: # ls -PTldU /usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/include/machine/endian.h lrwxr-xr-x 1 root wheel 33 Apr 29 12:38:12 2021 /usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/include/machine/endian.h -> ../../../sys/arm/include/endian.h # ls -LTld /usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/include/machine/endian.h -rw-r--r-- 1 root wheel 4311 Apr 28 02:03:34 2021 /usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/usr/include/machine/endian.h # ls -LTld /usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/sys/arm/include/endian.h -rw-r--r-- 1 root wheel 4311 Apr 28 02:03:34 2021 /usr/obj/BUILDs/13_0R-CA7-nodbg-clang/usr/13_0R-src/arm.armv7/tmp/sys/arm/include/endian.h But I see no evidence that -isysroot ( or any /usr/include ) is being put to use. -- You are receiving this mail because: You are the assignee for the bug.home | help
