Hi, Let me start by thanking you for all the support you give (it is impressingly fast).
So if I look in the repo, with the ppa installed, I can't find liburcu: $ cat /etc/apt/sources.list.d/lttng-ppa-precise.list deb http://ppa.launchpad.net/lttng/ppa/ubuntu precise main deb-src http://ppa.launchpad.net/lttng/ppa/ubuntu precise main (I have asked my admin to do an apt-get update) $ apt-cache search lttng lttng-modules-dkms - Linux Trace Toolkit (LTTng) kernel modules (DKMS) lttng-tools - LTTng control and utility programs liblttng-ust0 - LTTng 2.0 Userspace Tracer (libraries) liblttng-ust-dev - LTTng 2.0 Userspace Tracer (development files) liblttng-ctl-dev - LTTng control and utility library (development files) liblttng-ctl0 - LTTng control and utility library liblttng-ust-java-jni - LTTng 2.0 Userspace Tracer (JNI interface) liblttng-ust-java - LTTng 2.0 Userspace Tracer (Java support library) python-lttng - Python bindings for LTTng liblttng-ust-ctl2 - LTTng 2.0 Userspace Tracer (trace control library) $ apt-cache search liburcu liburcu-dev - a userspace RCU (read-copy-update) library - development files liburcu1 - a userspace RCU (read-copy-update) library liburcu2 - a userspace RCU (read-copy-update) library So it looks like my aptitude is not aware of a package called liburcu without a postfix… Even if I'd purge and reinstall (which seems like a very good idea) I don't see if I can access the right library this way.
