I've installed these: libmount-dev libcap-ng-dev libfuse-dev libpopt-dev libnuma-dev. libelf-dev I already had. And for clang I switched to distro-provided one. This reduced number of errors, but I still see some: clang: error: unable to execute command: Broken pipe clang: error: clang frontend command failed due to signal (use -v to see invocation) Makefile:259: recipe for target 'elfdep' failed Makefile:156: recipe for target 'all' failed Makefile:106: recipe for target '/linux/tools/testing/selftests/bpf/libbpf.a' failed timestamping.c:249:19: error: ‘SIOCGSTAMP’ undeclared (first use in this function); did you mean ‘SIOCGSTAMPNS’? ../../lib.mk:138: recipe for target '/linux/tools/testing/selftests/networking/timestamping/timestamping' failed mlock-random-test.c:8:10: fatal error: sys/capability.h: No such file or directory ../lib.mk:138: recipe for target '/linux/tools/testing/selftests/vm/mlock-random-test' failed Full log: https://gist.githubusercontent.com/dvyukov/5c334e7e7e136909cb66b23b9fb7d439/raw/965f84bd99deb361dcb567ce2e2654db5d270138/gistfile1.txt
