Mirai 编译踩坑

编译环境

Kali Rolling (2025.1a) x64
go version 1.10
gcc 14.2.0

参考：
https://www.cnblogs.com/lee-qi/p/11430166.html
https://kamisec.github.io/2020/02/Mirai%E5%B9%B3%E5%8F%B0%E7%9A%84%E5%AD%A6%E4%B9%A0-%E6%90%AD%E5%BB%BA%E7%AF%87/

问题 1：go 版本问题，使用 1.10 拉取仍然报错：

go get github.com/go-sql-driver/mysql

bash
package slices: unrecognized import path "slices" (import path does not begin with hostname)

• 删除现有 MySQL 驱动程序： rm -rf $GOPATH/src/github.com/go-sql-driver/mysql
• 克隆仓库并切换到兼容版本（如 v1.5.0）：

bash
git clone https://github.com/go-sql-driver/mysql.git $GOPATH/src/github.com/go-sql-driver/mysql 
cd $GOPATH/src/github.com/go-sql-driver/mysql 
git checkout v1.5.0

问题 2：gcc 版本过高，某些特性不支持：

在 mirai 下 build.sh debug telnet 时：

bash
/usr/bin/ld: /tmp/ccYv6tLe.o:/home/kali/Mirai-Source-Code/mirai/bot/includes.h:31: multiple definition of `LOCAL_ADDR'; /tmp/ccsVmAAb.o:/home/kali/Mirai-Source-Code/mirai/bot/includes.h:31: first defined here
/usr/bin/ld: /tmp/cciIC3rk.o:/home/kali/Mirai-Source-Code/mirai/bot/includes.h:31: multiple definition of `LOCAL_ADDR'; /tmp/ccsVmAAb.o:/home/kali/Mirai-Source-Code/mirai/bot/includes.h:31: first defined here

修改 build 脚本，将所有调用 gcc 的命令都添加-fcommon 编译标志，例如：

sh
gcc -std=c99 -fcommon tools/enc.c -g -o debug/enc

问题 3：交叉编译库下载失败：

只有 armv6l 下载成功，将其余的链接全部换为以http://distro.ibiblio.org/slitaz/sources/packages/c/起始即可，除了这三个都可以下载：

问题 4：使用 cross-compile.sh 交叉编译器安装后仍然找不到 gcc:

bash
┌──(root㉿kali)-[/home/kali/Mirai-Source-Code/scripts]
└─# ./cross-compile.sh

export PATH ...
┌──(root㉿kali)-[/home/kali/Mirai-Source-Code/scripts]
└─# mips-gcc
mips-gcc: command not found

将 PATH 写到 .bashrc 中：

bash
export PATH=$PATH:/etc/xcompile/mips/bin:/etc/xcompile/mipsel/bin:/etc/xcompile/armv4l/bin:/etc/xcompile/armv5l/bin:/etc/xcompile/armv6l/bin:/etc/xcompile/powerpc/bin:/etc/xcompile/sh4/bin:/etc/xcompile/sparc/bin

kali 的默认 shell 为 zsh，所以先进 bash，然后再运行 gcc 就 ok 了，为了方便将 go1.10 也加到这里： export PATH="/usr/local/go/bin:$PATH" 然后source ~/.bashrc就可以看到 go version 为 1.10，便于编译 mirai 本体

问题 5：编译 loader 时报错：

bash

直接修复代码： Fixed binary_init() return value in src/binary.c

• Added a proper return FALSE statement in the error path
• Changed the load() function to return TRUE on success
