It is nice of you to cook a patch for it. But be careful, I have tested it on my not that new version Ubuntu (10.10), yliu@yliu:~$ apt-cache showpkg liburcu-dev Package: liburcu-dev Versions: 0.4.6-1 No .pc config file *and* I looked at the atomic header structure uatomic_arch.h is the actual header we should include in the source file. And it seems that even with newest liburcu, we should also include this file instead of 'urcu/uatomic.h" to get backward compatible. I am not sure what version comes up in most command server edition, such as RHEL 6 and Debian stable, where we should support as well as possible. -- thanks, Yuan -- sheepdog mailing list [email protected] http://lists.wpkg.org/mailman/listinfo/sheepdog
