| Subject: [PATCH] MDEV-30554 RockDB libatomic linking on riscv64
 | |
| 
 | |
| The existing storage/rocksdb/CMakeCache.txt defined
 | |
| ATOMIC_EXTRA_LIBS when atomics where required. This was
 | |
| determined by the toplevel configure.cmake test
 | |
| (HAVE_GCC_C11_ATOMICS_WITH_LIBATOMIC).
 | |
| 
 | |
| As build_rocksdb.cmake is included after ATOMIC_EXTRA_LIBS
 | |
| was set, we just need to use it. As such no riscv64
 | |
| specific macro is needed in build_rocksdb.cmake.
 | |
| 
 | |
| As highlighted by Gianfranco Costamagna (@LocutusOfBorg)
 | |
| in #2472 overwriting SYSTEM_LIBS was problematic.
 | |
| This is corrected in case in future SYSTEM_LIBS is changed
 | |
| elsewhere.
 | |
| 
 | |
| Closes #2472.
