Hi, I'm banging my head agains the wall because I cannot seem to get this working. The problem is due to changing from automake to cmake building. But all my dlopens start failing with something like: load failed dlopen(build/lib/compressor/libceph_snappy.so) or dlopen(build/lib/libceph_snappy.so): build/lib/libceph_snappy.so: Undefined symbol "_ZN4ceph6buffer4list8iterator7advanceEl" If do a lookup for the name: nm build/lib/libceph_snappy.so |grep ceph6buffer4list8iterator7advanceEl if give me: U _ZN4ceph6buffer4list8iterator7advanceEl The parent/calling executable however has: 0000000000513de0 T _ZN4ceph6buffer4list8iterator7advanceEl Clearly dlopen is not able to match these 2 and succeed. Question: So on which part of the building is what switch missing. Thanx, --WjW
