Thanks for this information Kaleb. I'll check the changes I've done till now with the older versions of the libraries. I think I'm going to need at least the 0.8.* release of liburcu, as some new apis were introduced in it, which I'm using. I'll post the outcome of my tests back here.
For a start, I collected the various versions of liburcu (userspace-rcu in some) available in the different distros. This list is based on the distros for which we provide community built packages and test on. - Fedora 21 - 0.8.1 (0.8.5 in testing but stuck due to some breakages) - Fedora 20 - 0.7.7 (0.8.5 in testing but stuck due to some breakages) - EL7 - 0.7.9 - EL6 - 0.7.7 - Debian Wheezy - 0.6.7 - Debian Jessie - 0.8.5 (in testing) - Ubuntu Precise - 0.6.7 - Ubuntu Trusty - 0.7.12 - Ubuntu Utopic - 0.8.4 - Netbsd - 0.8.6 - Freebsd - 0.7.7 The list doesn't look too good. ~kaushal On Fri, Jan 30, 2015 at 6:30 PM, Kaleb KEITHLEY <kkeit...@redhat.com> wrote: > Hi, > > Just FYI, what you propose is called bundling in Fedora packaging > parlance, and Fedora's packaging guidelines forbid bundling.
