On glinux, from a newly cloned symbiflow-arch-defs repo, I ran make env as indicated by the README, and this happens:

I believe this is because your CXX variable is set to g++-6? If you unset CXX and CC, it will work? Recently gLinux removed old compiler versions. I got bit because of this issue because clang-7 no longer existed. However it isn't a problem with arch-defs.

Does symbiflow-arch-defs actually require a C++ compiler?

Yes, bitstream tools et/all?

I think conda init bash and restarting the shell fixes this.

At least, I did that, and make env successfully completes now.

I'm going to leave this open and look at it a bit more closely...

At least the README needs updated.
