vickycq 写了：建议另起炉灶，严格按 11 楼的流程执行。

完整流程示例：https://paste.debian.net/plain/787175

这是我的运行结果：
@ubuntu:~/tcp_wrappers_7.6$ patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch
patching file Makefile
patching file fix_options.c
patching file hosts_access.3
patching file hosts_access.5
patching file hosts_access.c
patching file hosts_options.5
patching file options.c
patching file percent_m.c
patching file rfc931.c
patching file safe_finger.8
patching file safe_finger.c
patching file scaffold.c
patching file socket.c
patching file tcpd.8
patching file tcpd.h
patching file tcpdchk.c
patching file try-from.8
patching file weak_symbols.c
patching file workarounds.c

注：和你给的那个相比少了：
patching file hosts_access.5 [420/1911]
patching file hosts_access.c
这两个文件，结果显示还是没变的

0. 说明硬件环境，操作系统

1. 执行以下指令将结果全部复制贴上来 2. 执行 patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch 后，查看 Makefile 第 149 行开始是否为以下内

抱歉，这是我复制错误。
