[FinnWilkinson]

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

[jandrovins]

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

[FinnWilkinson]

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