Description Alessandro Calorì 2021-09-19 09:15:51 UTC
Today I updated my (stable) Gentoo workstation and dev-util/lttng-ust has to be rebuilt due to dev-libs/userspace-rcu being bumped to 0.13. The rebuild fails during the configuration phase with the message:

checking for synchronize_rcu_bp in -lurcu-bp... no
configure: error: Cannot find liburcu-bp lib. Use LDFLAGS=-Ldir to specify its location.

Masking =dev-libs/userspace-rcu-0.13.0 solves the issue.

FWIW, I'm having the same issue:

configure: error: Cannot find liburcu-bp lib. Use LDFLAGS=-Ldir to specify its location.

Happy to provide extra info if helpful.

Please retry with dev-util/lttng-ust-2.12.1.
Comment 7 Alessandro Calorì 2021-09-20 05:59:37 UTC
I can confirm that dev-util/lttng-ust-2.12.1 now merges successfully with dev-libs/userspace-rcu-0.13.0 on my workstation. Thank you.
Comment 8 Yixun Lan archtester gentoo-dev 2021-09-24 06:10:06 UTC
so fixed at >=dev-util/lttng-ust-2.12.1, I'm closing it..
