我也遇到了同样的问题，但是在谷歌搜索中什么也没找到。幸运的是，我终于找到了答案。

解决方案： 将每个以 -1 结尾的 .c/.h 文件重命名为它在目录 external/iptables/extensions 和 extenal/iptables/include/linux/netfilter 中的原始名称（删除 -1）

原因： 这个问题是一个非常角落的问题。我从 Internet 下载了没有 .repo 的“打包”Android 源代码，而不是痛苦地从 google 中签出。它是导致错误的源代码包。源代码已签出到不区分大小写的文件系统，因此仅大写不同的“重复”文件名被 git 重命名。例如，在同一目录中有一个 xt_mark.h 和一个 xt_MARK.h。在不区分大小写的文件系统上，Git 会自动将后一个文件重命名为 xt-MARTK-1.h 以避免被覆盖。

external/iptables/extension/libext项目，有很多文件如

 libxt_set.c
 libxt_SET.c    => libxt_SET-1.c
 libxt_dscp.c
 libxt_DSCP.c   => libxt_DSCP-1.c

....

这些重复的文件名只是为了区分大小写。 它可能在大多数情况下都有效，但项目的 makefile 会枚举每个具有 libxt_xxx.c 格式的 c 文件，并为所有这些文件生成一个 init .c 文件。所以在生成的inittext.c中，函数入口如下：

libxt_DSCP-1_init();
libxt_SET-1_init();

已生成。 '-' 在函数/变量名中被禁止。
