With the log below, it appears that the "baddr" tracepoints and
probes are registered (which is why they work), but not your own event.
My recommendation as a next step is to try adding
#define _LGPL_SOURCE
At the very top of each implementation C file that uses the tracepoints
(both the code calling tracepoint() and the code where the probe provider
is located).
It appears that there might be some issue with dynamic linking of
lttng-ust-tracepoint.so on your system, so let's try this to try cornering
the issue. (FYI, these are dlopen/dlsym performed within
include/lttng/tracepoint.h).
One way to try understanding the problem is to add printf of the error values
near dlopen in this header. Another way is to use strace to see what is
going on.
Thanks,
Mathieu
