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.

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/.

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.

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? -- Sau!
