           Summary: gdb 7.2 can't build with lttng-ust 0.12
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: dexuan.cui@intel.com


I found gdb 7.2 can't build with lttng-ust 0.12 due to the API
change(http://www.mail-archive.com/ltt-dev@lists.casi.polymtl.ca/msg01839.html)
in lttng-ust 0.12. BTW, gdb-7.2 builds fine with lttng-ust 0.11.

I also tried
ftp://sourceware.org/pub/gdb/snapshots/branch/gdb-7.2.90.20110425.tar.bz2 and
got the same error:

For now, we have to use  --without-ust to disable ust in gdb-7.2. :-(

Is there a plan to support lttng-ust 0.12?

Thanks!
