Hi Alexander,
Thanks for sending this patch. Could you provide more details regarding the
linking errors?
lttng-ust must not depends on liburcu at runtime since commit
10544ee8af31afb239e3dfa71cb2fe09d3de3771
commit 10544ee8af31afb239e3dfa71cb2fe09d3de3771
Author: Mathieu Desnoyers <mathieu.desnoy...@efficios.com>

Remove runtime dependency on liburcu shared objects
Remove the runtime dependency on:
- liblurcu-bp.so
- liblurcu-cds.so
- compat futex code.
By integrating those into the lttng-ust project.
For rculfhash, only the minimum pieces needed by lttng-ust are
integrated (no auto-resize, no accounting).
lttng-ust still requires liburcu at build time for header dependencies.
