Thanks. I read the notes about mixing dynamic and static libraries, but at the moment I can't see why that affects me as I'm not doing anything clever with linking, my makefile simply has "-lrados -lradosstriper" in it, and I'm using gcc in a standard way. If I used "ldd" and "nm" on the .o and executables it looks normal to me. That said, we have a unique and special build system here which could be doing something odd, but I have delved through the logs and the compiler and linker options look sane. thanks for your time On 21/09/15 18:14, Jason Dillaman wrote: > This is usually indicative of the same tracepoint event being included by both a static and dynamic library. See the following thread regarding this issue within Ceph when LTTng-ust was first integrated [1].
