trying to investigate.
all these symbols are in the installed /usr/lib64/liblz4.so.1.6.0

yeah, I don't see lz4 in there
--with-librocksdb-static is true; src/rocksdb/librocksdb.a does indeed still have unbound references to LZ4*
rex001 had lz4-devel installed, which caused rocksdb to configure itself to use LZ4...but nothing consumed the '-llz4' snippet it placed in make_config.mk, so the link didn't know to use it.
We should probably explicitly disable lz4, or change things to set flags in the consuming link from the autoconfigured flags in rocksdb/make_config.mk

I got into this bug trying to build ceph on a machine that runs Arch. Since arch does not have different packages for -devel the lz4 headers are installed by default (systemd has lz4 as a dependency). Is there any workaround for this bug? Thanks
- Status changed from New to Fix Under Review
we'd better make sure our building env is a clean room, otherwise the configure script will detect the installed and bzlib and liblz4, and the created ceph-osd and ceph-mon executable will be dynamically linked against these libraries.
- Status changed from Fix Under Review to Resolved
