I was building my test program on and for Red Hat Enterprise Linux version 6*, using the rpm files with version -0.94.3-0.el6.x86_64. This gives me the lttng clash. I then took a RHEL7.1 box and build my test program against the el7 versions of the packages (namely 0.94.3-0.el7.x86_64) and it works just fine, no problems with lttng clashes at all. When I examine the libraries for differences using ldd, I find that the el7 versions don't need lttng at all, but the el6 do. So it appears that the el6 libraries had -WITH-LTTNG enabled when they were built, but the el7 don't. I've tried building ceph from sources on centos6 to get a copy of the libraries without lttng. I've tried both git cloning the hammer branch, or downloading the .tar.bz2 and using rpmbuild as per the wiki, but neither work, something always fails critically along the way :-( * this target platform is already chosen, I can't change it, I'd like to switch to RHEL7 but sadly can't. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
