hi, Is EPEL splitting into 5.5 vs 5.x? Is memcached going to get a rebuild now that RHEL 5.5 has been released? I asked my inside source and he says:
> EPEL only provides compatibility to the latest RHEL tree and not the
> older ones. So once we transition EPEL to 5.5 build trees (after
> CentOS-5.5 comes out or a week depending on how long it takes... ) I
> would go and rebuild with a larger builld number. It won't work with
> EL-5.4 unless we come out with a compat library also.
So this is ugly. memcache really needs a new libevent to run well. Over on the memcache mailing list there's talk about bundling libevent directly into the memcached package to avoid old broken libevent libs. As an alternate is it possible for a new libevent to be included into EPEL that could be used by memcached? I suppose it would have to be a different package name -- something like libevent14? Then we'd also have to coordinate the Obsoletes for libevent in EL-6.... RHEL 5.5 has libevent 1.4.13 (that's why the upgrade path is broken with the current memcached from EPEL). memcached-1.4.5-1.el5 has been submitted as an update for Fedora EPEL 5. http://admin.fedoraproject.org/updates/memcached-1.4.5-1.el5 *** Bug 580248 has been marked as a duplicate of this bug. *** memcached-1.4.5-1.el5 has been pushed to the Fedora EPEL 5 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update memcached'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/memcached-1.4.5-1.el5 Maybe a update of libevent should be made? RHEL's ABI stability should be kept. We need a compat libevent-1.1a.so.1 Kirby, can you file a bug for libevent compat in Enterprise Linux 5 category? memcached-1.4.5-1.el5 has been pushed to the Fedora EPEL 5 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update memcached'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/memcached-1.4.5-1.el5 memcached-1.4.5-1.el5 has been pushed to the Fedora EPEL 5 stable repository. If problems still persist, please make note of it in this bug report. https://bugzilla.redhat.com/show_bug.cgi?id=581101#c1 As a workaround, you can get the compat-libevent-11a package from RPMforge (http://rpmforge.net). -Steve |
Description of problem: memcached fails to install because of dependency problems with libevent on the rhel 5.5 test release. Error: Missing Dependency: libevent-1.1a.so.1()(64bit) is needed by package memcached-1.2.8-1.el5.x86_64 (epel) Version-Release number of selected component (if applicable): memcached: 1.2.8-1.el5 libevent: 1.4.13-1 (default version on rhel 5.5) How reproducible: Try and install memcached on rhel 5.5 Steps to Reproduce: 1. Grab rhel 5.5 early release 2. Activate epel 3. yum install memcached Actual results: [michael@monster yum.repos.d]$ sudo yum install memcached Loaded plugins: rhnplugin, security rivermusecore-testing | 1.1 kB 00:00 rivermusepro-testing | 1.1 kB 00:00 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package memcached.x86_64 0:1.2.8-1.el5 set to be updated --> Processing Dependency: libevent-1.1a.so.1()(64bit) for package: memcached --> Finished Dependency Resolution memcached-1.2.8-1.el5.x86_64 from epel has depsolving problems --> Missing Dependency: libevent-1.1a.so.1()(64bit) is needed by package memcached-1.2.8-1.el5.x86_64 (epel) Error: Missing Dependency: libevent-1.1a.so.1()(64bit) is needed by package memcached-1.2.8-1.el5.x86_64 (epel) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest The program package-cleanup is found in the yum-utils package. Expected results: Memcached to install successfully.
