List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 09 Jun 2013 13:49:22 -0000 Hi Guys, I started off with wanting to run postgresql on FreeBSD with DTrace support enabled but ran into various problems, digging further I discovered that the issue is not specific to Postgreqsl. My test system was FreeBSD-CURRENT/amd64 but I went back to 8.4/i386 to test. On fresh 8.4 install it's not possible to build a kernel or world WITH_CTF=1, build fails with WITH_CTF & WITHOUT_CTF can't both be set On FreeBSD-CURRENT (r251249 from last Sunday), postgresql & firefox build --with-dtrace but probes never show up when running dtrace -l On FreeBSD 9.1-STABLE (r250009) postgresql wouldn't build with dtrace support enabled. Failing with Assertion failed: (nrc == rc), function _libelf_resync_sections, file /usr/src/lib/libelf/elf_update.c, line 341. gmake: *** [utils/probes.o] Abort trap: 6 (core dumped) gmake: *** Deleting file 'utils/probes.o' *** [do-build] Error code 2 Previously reported here & http://lists.freebsd.org/pipermail/freebsd-questions/2013-May/250843.html I was wondering what the percieved state of DTrace support was from the developers perspective, is this known behaviour? Should I rais a PR to flag the postgresql port broken when attempting to build with dtrace support? Sevan / Venture37
