Hmm, interesting, I haven't seen this issue before. I recently pushed some fixes to get it setup on 20.04. Can you try again and see if this issue still persists? I tested with 20.04 and Clang-10. There is a docker image with a setup for focal that you can get using the instructions here

Now I can compile gramatron on ubuntu focal, thanks But I can't compile gramatron on newest AFL++ as custom mutator

...
...
[+] Json-c successfully prepared!
[+] Builing gramatron now.
