Hi, William, When compiled the selftests/bpf in my centos 7 based system, I have the following failures,
clang -I. -I./include/uapi -I../../../include/uapi -Wno-compare-distinct-pointer-types \ -O2 -target bpf -emit-llvm -c test_tunnel_kern.c -o - | \ llc -march=bpf -mcpu=generic -filetype=obj -o /data/users/yhs/work/net-next/tools/testing/selftests/bpf/test_tunnel_kern.o test_tunnel_kern.c:21:10: fatal error: 'linux/erspan.h' file not found #include <linux/erspan.h> ^~~~~~~~~~~~~~~~ 1 error generated. Maybe I missed some packages to install? Thanks!
