Subject: gdb and lttng-ust 0.12
Date: Sun, 24 Apr 2011 13:16:50 -0700 [thread overview]
Message-ID: <4DB48532.3030605@linux.intel.com> (raw)
Dexuan,
It seems that when you updated lttng-ust to 0.12, it installed an
/usr/include/ust directory that GDB now finds. This caused the
gdbserver code to not build.
I investigated this and it seems to be due to gdb having a dependency on
UST that causes GDB not to compile. I think at this point we may want
to continue with UST disabled in gdb.
To reproduce this, ensure that lttng-ust-0.12 is built before building
gdb and you should see a compilation failure.
My concern here is that if fix the GDB compilation failures, what else
is going to fail as far as debugging with UST enabled on the remote, I
know this feature is something we want, and should probably report to
the GDB upstream.
The fix seems to be as simple as adding "--without-ust" to the gdb
EXTRA_OECONF line.
Comments?

so a different set of flags).
