I was correct about the search order for include files being different before -r335782 vs. -r335782 and later: head -r335812 uses the gcc headers (and fails): ignoring nonexistent directory "/usr/local/lib/gcc/x86_64-unknown-freebsd12.0/6.4.0/include-fixed" ignoring nonexistent directory "/usr/local/lib/gcc/x86_64-unknown-freebsd12.0/6.4.0/../../../../x86_64-unknown-freebsd12.0/include" #include "..." search starts here: #include <...> search starts here: /usr/src/lib/msun/x86 /usr/src/lib/msun/ld80 /usr/src/lib/msun/i387 /usr/src/lib/msun/src /usr/src/lib/libc/include /usr/src/lib/libc/i386 /usr/local/lib/gcc/x86_64-unknown-freebsd12.0/6.4.0/include /usr/obj/amd64_xtoolchain-gcc/amd64.amd64/usr/src/amd64.amd64/obj-lib32/tmp/usr/include End of search list. head -r335245 uses the FreeBSD headers and works: ignoring nonexistent directory "/usr/local/lib/gcc/x86_64-unknown-freebsd12.0/6.4.0/include-fixed" ignoring nonexistent directory "/usr/local/lib/gcc/x86_64-unknown-freebsd12.0/6.4.0/../../../../x86_64-unknown-freebsd12.0/include" ignoring duplicate directory "/usr/obj/amd64_xtoolchain-gcc/amd64.amd64/usr/src/amd64.amd64/obj-lib32/tmp/usr/include" #include "..." search starts here: #include <...> search starts here: /usr/src/lib/msun/x86 /usr/src/lib/msun/ld80 /usr/src/lib/msun/i387 /usr/src/lib/msun/src /usr/src/lib/libc/include /usr/src/lib/libc/i386 /usr/obj/amd64_xtoolchain-gcc/amd64.amd64/usr/src/amd64.amd64/obj-lib32/tmp/usr/include /usr/local/lib/gcc/x86_64-unknown-freebsd12.0/6.4.0/include End of search list. Might this reversal have other effects even for architectures for which the code does compile via devel/*-gcc ? === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
