That goes back to "how do I actually use this feature" which I have not found a cogent description of from a simple user perspective, and my attempt was by making this diff to the wip/bind920/ package: : {1} cd /usr/pkgsrc/wip/bind920 : {2} git diff . diff --git a/bind920/Makefile b/bind920/Makefile index d270b440ea..6f706070c5 100644 --- a/bind920/Makefile +++ b/bind920/Makefile @@ -29,6 +29,12 @@ GNU_CONFIGURE= yes CHECK_FILES_SKIP= bin/tests/system/system-test-driver.sh MAKE_ENV+= WRKDIR=${WRKDIR} PREFIX=${PREFIX} +# Try to use thread sanitizer +#PKGSRC_COMPILER= clang # does not work with thread sanitizer(!) +CFLAGS+= -g +CFLAGS+= -fsanitize=thread +LDFLAGS+= -lexecinfo + .if ${OPSYS} == "Linux" && !exists(/usr/include/sys/capability.h) CONFIGURE_ARGS+= --disable-linux-caps .endif : {3} and I tried to replicate the build & running of one of the tests configure does to check whether executables produced by the C compiler complete successfully, which the posted program with the given options didn't when trying with clang as the C compiler. If I recall correctly, I had to add the LDFLAGS entry after I switched to use gcc as the C compiler, and with that the build at least succeeded. I have yet to test the result, though, much less trying to run this in "production". Regards, - HÃ¥vard
