When I try to install xdp-tools I get the following error:

Errors from LLC usually appear when there's a version mismatch between llc and clang. Probably the configure script picked up wrong versions of one of them? You can look in config.mk to see which binaries are being used, and to change them you can pass explicit versions to configure like:

LLC=llc-16 CLANG=clang-16 ./configure

Thanks matching the llc and clang version solved the issue.
