This bug report shows that you are using the clang-4.0 package from the Ubuntu archive and that it fails to find architecture-specific headers under /usr/include/s390x-linux-gnu, so that is certainly a valid bug in that package. However, clang is not a supported package in Ubuntu main.
In Ubuntu 18.04, the default version of clang is clang-6.0, not clang-4.0. Does this build work with clang-6.0? ** Package changed: linux (Ubuntu) => llvm-toolchain-4.0 (Ubuntu) ** Changed in: llvm-toolchain-4.0 (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1750388 Title: 17.10 - BPF test tool build with errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1750388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
