It appears that it is essentially a private dependency of libc which is not listed in libc.so. It's very similar to `-lrt`. I suspect we could probably add it here: https://github.com/apache/arrow/blob/98f352ed8325e9d9c01f9d840dec221311f7fb22/cpp/CMakeLists.txt#L879 @nealrichardson 's solution is mostly correct and would work for R (and other consumers of the Arrow static library) but would fail for anyone consuming Arrow as a shared library on a raspberry pi. So I think, in addition to listing it as a private lib, Arrow will still need to link it when building the shared library. The Arrow shared library would build without `-latomic` because Arrow doesn't make any calls to `-latomic` (those calls are made by `libc.so`). -- This is an automated message from the Apache Git Service.
