Hi Christian! I have ceph 0.27 installed. I downloaded it from: http://ceph.newdream.net/download/ceph-0.27.tar.gz
I found the following rados/rbd included files at: /usr/include/rados /usr/include/rados/buffer.h /usr/include/rados/crc32c.h /usr/include/rados/librados.h /usr/include/rados/librados.hpp /usr/include/rados/page.h /usr/include/rbd /usr/include/rbd/librbd.h /usr/include/rbd/librbd.hpp I also found the following rados/rbd lib files at: /usr/lib64/librados.so -> librados.so.2.0.0 /usr/lib64/librados.so.2 -> librados.so.2.0.0 /usr/lib64/librados.so.2.0.0 /usr/lib64/librbd.so -> librbd.so.1.0.0 /usr/lib64/librbd.so.1 -> librbd.so.1.0.0 /usr/lib64/librbd.so.1.0.0 The QEMU configure script is looking for a function called 'rados_initialize' within the header file 'rados/librados.h'. I checked the rados include/lib files for that function, but I don't see it: # grep -rin rados_initialize /usr/include/rados/* # strings /usr/lib64/librados.so | grep -i rados_initialize Thanks, Dyweni > Hi Dyweni, > > are you sure that you have installed ceph (especially librados and the > header files)? > > Josh's patches use the newer librbd from ceph 0.27.
