If there is no peculiar reasons to use lttng-tools 2.5 with a HEAD of the lttng-modules master branch project, I recommend that you start fresh and reinstall the following from source: userspace-rcu v0.9.3, lttng-modules v2.9.1, lttng-ust v2.9.0, lttng-tools v2.9.4. Make sure to remove previously installed packages and all libs and header installed related to lttng. Could you provide the content of config.status (generated after ./configure) for userspace-rcu, lttng-ust, lttng-tool. So we can address the compilation issue from the parallel thread [1].
