Thanks, @Alessandro-Barbieri . I think we only call libyogrt from the main SCR library, so in theory we shouldn't have to link to libyogrt in the serial binaries.

Does this PR resolve a link error that you're seeing? Can you forward the error info?

Thanks, @Alessandro-Barbieri . That's helpful. For some reason, I don't see the same error in my link. Maybe the linker version or option is the difference.

Rather than add libyogrt to the link, I'm wondering if we can drop the scr_env.c file from the objects in the serial binaries. Does it work if you drop scr_env.c from the noMPI sources here?

That's because yogrt_remaining is used in scr_env.c and it will end in scr_base.a (in this case you get no errors because it's static)
but if you try to build scr_base.so as in #454 you'll get that error at link time
