Hi, I think I had something like this before, but cannot find it in my Email archive... I'm trying to build head, which works for a long way, but it gets into trouble when linking ceph-mon. Errors out on not being able to find some of the references in librocksdb... librocksdb.a is recent: > ll src/rocksdb/librocksdb.a 80012 -rw-rw-r-- 1 wjw tegenbosch 305720086 Sep 21 10:40 src/rocksdb/librocksdb.a And it seems defined: > nm -e src/rocksdb/librocksdb.a | grep NewLRU U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd 0000000000001fd0 T _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd U _ZN7rocksdb11NewLRUCacheEmibd Strange thing that this is a routine that is only added recently. Which suggests that it tries to bind against an older librocksdb ..?? Then I checkout a completely fresh head in a nes directory, still the same error. So I've deleted anything in /usr/local/ that looks like a librocksdb-library. But still it hits error.
