LTTng » LTTng-UST

Ubuntu 12.04.5 LTS precise (64-bit) running 3.9.3 kernel

While upgrading from lttng-ust-2.3.0 to lttng-ust-2.9.0-pre-59-f4a90c3, after also upgrading lttng-modules (lttng-modules-2.7.0-stable to lttng-modules-2.9.0-pre-17-152fe7f) and userspace-rcu (userspace-rcu-0.8.0 to userspace-rcu-0.10-pre-2-d8a4979), the lttng-ust make fails with:

That same set (lttng-modules-2.9.0-pre-17-152fe7f, userspace-rcu-0.10-pre-2-d8a4979, lttng-ust-2.9.0-pre-59-f4a90c3) compiled just fine on another machine.

This may be an artefact of the upgrade, so I'll do a complete uninstall then try again.
