The last version of Ruby in Fedora/RISCV is v2.5.7. It seems that anything above v2.5 series fails to build (tried multiple times with different releases over a long time).

All the builds fail the same:

Over time different kernels, glibc version, QEMU VM vs. HW, firmware, etc were tried with the same result.

According to that log, seems CAS is not available.

• Is duplicate of Bug #16774: Don't require sub-word atomics added

[mame (Yusuke Endoh)]

I believe that it is already fixed on master by the patch of #16774.
