GDB support in UST was temporarily removed from UST by the commit you pointed out. GDB CVS trunk is still able to build with UST 0.11 and URCU 0.5.3. > I also noticed that the header file ust/ust.h is not installed, thus > making the configure process useless.

I was going to send a patch for the latter, but decided to ask > first. If UST 0.11 is installed, everything still works well, otherwise, UST stuff will not be compiled. So I disagree to disable it temporarily. There has been a PR for this issue, gdb 7.2 can't build with lttng-ust 0.12 http://sourceware.org/bugzilla/show_bug.cgi?id=12699 -- Yao (齐尧)
