1 # 2 # Shown below is a simplified dependency graph of the OpenZFS provided 3 # libraries. Administrative commands (`zfs`, `zpool`, etc) interface with 4 # the kernel modules using the `libzfs.so` and `libzfs_core.so` libraries. 5 # These libraries provide a stable ABI across OpenZFS point releases. 6 # 7 # The `libzpool.so` library is a user space build of the DMU and SPA layers 8 # used to implement debugging tools (zdb) and code validation tools (ztest). 9 # These library interfaces are subject to change at any time. 10 # 11 # 12 # CMDS: zhack/ztest/zdb/ zfs/zpool/zed/ 13 # raidz_{test,bench} zinject/zstream 14 # | | 15 # LIBS: | | libzfsbootenv* 16 # | | | 17 # | | | 18 # libzpool libzfs* ----------------+ 19 # | | | \ / | | | 20 # libicp --/ | | \ / | | \------- libshare 21 # | | \ / | | 22 # libzstd ---/ | \ / | \--------- libuutil 23 # | \ / \ | | 24 # libunicode --/ \ / \ | | 25 # \ / \ | | 26 # libzutil libzfs_core* | | 27 # | | | | \ | | | | 28 # | | | | | | | | | 29 # | | | | | | | | | 30 # libtpool -------------/ | | | \---- libnvpair* | | | 31 # | | | | | | 32 # libefi -----------------/ | \------ libavl* --------/ | 33 # | | | 34 # \-------- libspl ----+------/ 35 # 36 # 37 # NB: GNU Automake Manual, Chapter 8.3.5: Libtool Convenience Libraries 38 # These nine libraries are intermediary build components. 39 # 40 # * - A stable ABI is provided for these libraries; 41 # when performing an ABI check the following options are applied: 42 # 43 # --no-unreferenced-symbols: Exclude symbols which are not referenced by 44 # any debug information.
