大佬，这是什么情况？求解

yzslab commented 6 years ago

查找你的toolchain使用的头文件"netinet/tcp.h"的路径，编辑打开，查找struct tcphdr的check、doff需要定义什么宏才能启用，使用gcc的-D参数定义所需的宏进行编译。

CzzzzzHyq commented 6 years ago

struct tcphdr { be16 source; be16 dest; be32 seq; be32 ack_seq;

} tcp.h下有这个tcphdr结构体的定义，那应该怎么开启？ 直接-D __u16 这样吗？

yzslab commented 6 years ago

请把tcp.h的内容完整上传

麻烦大佬了

你的toolchain是哪里下载的，提供一下下载地址吧，我看看。

CzzzzzHyq commented 6 years ago

https://downloads.openwrt.org/releases/17.01.2/targets/ar71xx/nand/lede-sdk-17.01.2-ar71xx-nand_gcc-5.4.0_musl-1.1.16.Linux-x86_64.tar.xz 刚刚在吃饭 不好意思呀

yzslab commented 6 years ago

staging_dir/toolchain-mips_24kc_gcc-5.4.0_musl-1.1.16/include/netinet/tcp.h的77行：

#ifdef _GNU_SOURCE

用以下命令编译程序（记得替换TOOLCHAIN_GCC为你toolchain的gcc）：

TOOLCHAIN_GCC -D_GNU_SOURCE main.c -o CCDGUTNetCrackerR
CzzzzzHyq commented 6 years ago

已成功！谢谢大佬！

Subdue0 commented 5 years ago

按大佬说的，加了参数，-D_GNU_SOURCE，编译的确是通过了，但是编译出来的东西不正常，运行/usr/sbin/CCDGUTNetCrackerR br-lan daemon，没办法以守护进程运行。 出现提示： Random string: FpouCwDtHD Delete firewall rule. Add firewall rule. 然后本来正常的网络，直接没网了。这咋办
