I hope Toni can help out here, he found outr that when using threads, you must declare the function prototype explicitly, but I'm not at all sure this is your issue. > > Issue with the above approach was: > https://lists.fedorahosted.org/pipermail/vdsm-devel/2013-August/002537.html > > So we thought of having an extension module that makes use of libgfapi > and provides the statistics, which can be used in vdsm. > > what would be the better approach to resolve this ? Please provide us > your suggestions. In my opionion, the python module that you suggest makes sense - but it should be part of libgf - it is their's python binding (or part thereof). _______________________________________________ vdsm-devel mailing list vdsm-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel
