Note that UST is not yet ready for the lttng-tools integration... This

still use basic trace command of lttng-tools to control UST.
But, for now, you can fix that quickly by changing this to
"libustctl/Makefile.am" from the git source of ust.
- $(top_builddir)/libustcomm/libustcomm.la
+ $(top_builddir)/libustcomm/libustcomm.la \
+ $(top_builddir)/snprintf/libustsnprintf.la
Recompile and install ust and should be fine :)
Don't hesitate for any other problems/comments.
Thanks...Instead of changing the ust release, I could try retrograding
lttng-tools to its last compatible commit. Which would that be?
Actually, there is no "compatible commit" at this time for lttng-tools
and UST. This is why there is no release yet of lttng-tools. It is still
in very active development and should NOT be use in production yet.
I guess what I really need to know is what is the most recent *coherent* set of
commits from git.dorsal.polymtl.ca and git.lttng.org?
git.lttng.org for everything! The dorsal git is for internal development
and nothing "really" public.
On a somewhat related topic, I've found that the git.dorsal.polymtl.ca
lttng-agent (2011-03-23) is broken since 2011-02-25. It relies on
ustctl_force_switch(pid_t pid), which appeared with the 2011-01-31 ust 0.11-0.12
commit ("Rename libustcmd to libustctl") --- this function was called
ustcmd_force_switch before then. But on the 2011-02-25 ust 0.11-0.12 commit
("libustctl: use direct socket communication"), ustctl_force_switch(pid_t pid)
changed its signature to ustctl_force_switch(int sock, const char *trace).
Yes! It is broken and there is people working on moving it to support
the new liblttngctl (part of lttng-tools).
Cheers!
David
