Hello everyone,

make[3]: *** [_babeltrace_la-babeltrace_wrap.lo] Error 1
I got the source code by checking out bindings/python (git
checkout bindings/python).
I will be grateful if someone would tell how to fix the error.
Babeltrace API changed since this was made. To fix it, simply edit
the appropriate lines of the
lttng.i.in swig file in extras/bindings/swig/python (see the
CTF/EVENTS.H section of the file) and
I meant bindings/python/babeltrace.i.in
make sure all function declarations match the ones in
include/ctf/events.h
From the error message, most (if not all) *const struct definition*
args must be changed to
*const struct declaration*
This might yield some errors in the Python code itself regarding
Definition objects.
That class would need to be rewritten to fit the new API, along with
the corresponding functions.
But it should compile anyway
Also the 3 BT_SEEK_END lines must be changed to BT_SEEK_LAST
Hope this helps
Danny
This branch is currently in development, and might be out of sync with
the master branch of babeltrace at the moment. We don't have immediate
plans to work on it, but bontributions are welcome.
Thanks,
