After the preceding error is temporarily avoided, the following error message is displayed when the compilation continues:
/home/wcy/code/kmesh/oncn-mda/ebpf_src/sock_redirect.c:23:31: error: use of undeclared identifier 'NULL'
struct sock_key *redir_key = NULL;
It looks like some basic header files are not included. pls check it, thanks.
