Hi guys,
I have a system running 10-CURRENT (r250217) which I've built Postgresql
9.2.4 with DTrace support enabled on & a VM running 9.1-STABLE (r250009)
which I'm unable to build it on.
On 10-CURRENT the problem is that dtrace -l does not list the postgresql
provider.
My make.conf on both system is
STRIP=
CFLAGS+=-fno-omit-frame-pointer
on 9.1-STABLE the build fails 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
on 10-CURRENT there are warnings generated but the build completes &
installs
