I am having similar issues. It was fine installing on my Mac but ubuntu does not appear to function properly.

This should probably be filed upstream at https://github.com/CLD2Owners/cld2 (if at all).

It says that scoreonescriptspan.h uses #include <stdio.h>, which via /usr/include/features.h tries to include sys/cdefs.h and can't find it.

On Ubuntu 18.04.3 LTS, this header is present at /usr/include/x86_64-linux-gnu/sys/cdefs.h. On other versions of Ubuntu, you might need to install one of several development libraries.
