Please try and use the additional-sme-support branch with GCC. Clang is likely failing due to missing header files that aren't being pointed to properly at compile time
The first error was solved with the new commit in additional-sme-support, but I still found errors from the unknown type name 'uint8_t. Are you sure it is failing for missing headers? I solved it with the following patch. It seems src/include/simeng/Register.hh is missing the cstdint header. With this change the clang compilation works as well:
diff --git a/src/include/simeng/Register.hh b/src/include/simeng/Register.hh

Thanks for letting me know. I'll add this header to Register.hh now and update the branch
