We added support for RCU locks in 3.3 which required the use of atomics (or emulated atomic where they couldn't be supported), but those were in libcrypro not liberal
Right - its supposed to fallback to emulated atomic calls where atomics aren't available on a particular platform.
Some platforms have some atomics support but you have to link in a separate atomics library to get it to work. You might try adding "-latomic" to Configure command line and see if that helps at all.

Are they really needed somewhere? I see include/internal/refcount.h talks about C11 atomics and yet the entire code base is supposed to be C90 clean. See section the OpenSSL Coding Style policy : https://www.openssl.org/policies/technical/coding-style.html <https://www.openssl.org/policies/technical/coding-style.html> Chapter 14: Portability To maximise portability the version of C defined in ISO/IEC 9899:1990 should be used. This is more commonly referred to as C90. ISO/IEC 9899:1999 (also known as C99) is not supported on some platforms that OpenSSL is used on and therefore should be avoided. Perhaps I need to define OPENSSL_DEV_NO_ATOMICS ? Dennis Clarke RISC-V/SPARC/PPC/ARM/CISC UNIX and Linux spoken
