You probably used the wrong ceph headers. The default ceph install is going to go into /usr/local. System packages, which on many modern distributions will include ceph dependencies, will go into /usr. If you've got both running around, you need to make sure that the headers you use at compile time match the libraries you use at runtime. A memory fault is a typical symptom when you botched this. You might be able to just de-install the system provided packages; but check first to see it doesn't remove something you want to keep. At build time, you might look for lines like these -I $H/include -L $H/lib -Wl,-rpath,$H/lib on the compile line(s) to point at headers and runtime libraries. Note that many modern build systems hide the actual compile commands by default. Sometimes can also use "LD_LIBRARY_PATH" at runtime to point at the libraries you want; but first use "objdump -p " to verify there's no "RPATH". If there is an rpath, you may be able to use "chrpath" to change it. -Marcus Watts _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
