Is `libatomic` still required to build Iceoryx?

[t0ny-peng]

Brief feature description

It seems libatomic is required for iceoryx_hoof if built for LINUX. I'm curious is this still required? I've been testing with GCC8 on x86_64 and the compiler generates the correct atomic instructions in the output binary.

Detailed information

In the change log, it's stated that libatomic is added for RHEL. Is that still the case now? Thanks!

• Add libatomic to dependency list in iceoryx_utils for RHEL

The reason I'm asking this is because libatomic isn't a standard package, e.g., some Clang toolchains doesn't provide this and only GCC ones do.

Thanks!
