From mboxrd@z Thu Jan 1 00:00:00 1970 From: Daniel.Thibault@drdc-rddc.gc.ca (Thibault, Daniel) Date: Mon, 21 Jan 2013 09:52:55 -0500 Subject: [lttng-dev] Odd dependency for lttng-ust Message-ID: <3CA1A65C03C1A34C81BBC6272782E696987880@valcartierex01.valcartier.drdc-rddc.gc.ca> I'm starting from a clean Ubuntu 12.04 installation after adding the various prerequisites of the git.lttng.org LTTng 2 packages: LTTng 2 Packages (in the proper dependency order): lttng-modules (2.1.0+-c6403de) userspace-rcu (0.7.6-da9bed2) lttng-ust (2.1.0+-340f776) lttng-tools (2.1.1+-281047b) Prerequisites installed: automake binutils-gold bison flex libpopt-dev libtool libuuid1 python-dev swig2.0 kernel's headers (i.e. linux-headers-generic) texinfo g++ After making and installing lttng-modules and userspace-rcu successfully, lttng-ust's configure fails with: checking for _cds_lfht_new in -lurcu-cds... no configure: error: Cannot find liburcu-cds lib, part of Userspace RCU 0.7 or better. This occurs even though userspace-rcu installed /usr/local/lib/liburcu-cds. It seems I must install liburcu-dev from the LTTng PPA (because the current Ubuntu liburcu-dev is 0.6.7 while lttng-ust requires 0.7 or better) before I can configure lttng-ust properly. This is a weird bootstrapping problem: could the userspace-rcu package's install be incomplete? Daniel U.
