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?

Hi Saul,
Thanks very much for the investigation!
I can reproduce the issue now when I build gdb after building lttng-ust (previously looks I built them in the reverse order, so didn't catch it.)
I haven't understood why this issue occurred after I upgraded ust from 0.11 to 0.12 as 0.11 actually installs /usr/include/ust, too. And gdb was not upgraded recently.
I'm looking into this now and will update asap.
Thanks,
-- Dexuan

Hi Saul,
I prefer "continue with UST disabled in gdb" for now.
I'm investigating more to get an in-depth understanding about the issue. e.g., ust-0.11 doesn't break building gdb while ust-0.12 does -- however both 0.11 and 0.12 install /usr/include/ust/.
Thanks,

Ok, I have a patch queue'ed up already with this fix, I will push it as
part of a consolidated request later tonight.

I agree, I am not sure why this is happening also, I thought that I did
installs of 0.11 and did not see the ust directory, maybe I did not
force or something. Maybe diff the marker.h files and see if there are
differences?

Hi Saul,
Due to the API change in ust-0.12, we'll have to wait upstream gdb's fix (I verified the latest gdb snapshot gdb-7.2.90.20110425 has the same issue. I will report a bug in gdb bugzilla) .
I've reported http://bugzilla.pokylinux.org/show_bug.cgi?id=1005 to record this issue.
Thanks,

Hi Saul,
I prefer "continue with UST disabled in gdb" for now.
I'm investigating more to get an in-depth understanding about the issue. e.g., ust-0.11 doesn't break building gdb while ust-0.12 does -- however both 0.11 and 0.12 install /usr/include/ust/.

Hi Saul,
Thanks very much for the investigation!
I can reproduce the issue now when I build gdb after building lttng-ust (previously looks I built them in the reverse order, so didn't catch it.)
I haven't understood why this issue occurred after I upgraded ust from 0.11 to 0.12 as 0.11 actually installs /usr/include/ust, too. And gdb was not upgraded recently.
I'm looking into this now and will update asap.
Thanks,

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?
