Hi everyone, I successfully installed and used LTTng on x86 and x64 (kernel event, userspace, and other tools like TraceCompass). Now, I am looking for a way to use LTTng on other processors (arm32, ...). I tried to follow the tutorial and, to be honest, I am quite not lost on step 2. (libuuid, popt, libxml2) https://lttng.org/docs/v2.12/#doc-instrumenting-32-bit-app-on-64-bit-system My current issue is on the step 3. During the installation (./configure), I have the following error : error: Cannot find liburcu-bp 0.11 or newer. Use LDFLAGS=-Ldir to specify its location. This file - liburcu - is in /usr/local/lib32 : Ubuntu Pastebin This topic was started a long time ago here : https://lists.lttng.org/pipermail/lttng-dev/2013-February/019641.html Would you mind helping me ?
