第一步：看编译源代码文件 Makefile

# $FreeBSD: releng/11.1/sys/modules/ipsec/Makefile 319188 2017-05-30 04:36:11Z ngie $

.PATH: ${SRCTOP}/sys/net ${SRCTOP}/sys/netipsec

SRCS=    if_ipsec.c ipsec.c ipsec_input.c ipsec_mbuf.c ipsec_mod.c \
    ipsec_output.c xform_ah.c xform_esp.c xform_ipcomp.c \
    opt_inet.h opt_inet6.h opt_ipsec.h opt_sctp.h 
SRCS.INET=    udpencap.c

opt_ipsec.h:
