64位Ubuntu运行或调试32位程序

1 问题

最近在做lab2，使用64位的Ubuntu发现无法调试和运行：

➜  lab ./bomb 
zsh: no such file or directory: ./bomb

2 解决

ubuntu 64位下可以兼容32位程序的运行，但是必须要有32位基础库的支持才行。下面进行安装：

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
sudo apt install lib32z1

安装完成后可以运行和调试了：

➜  lab ./bomb 
Welcome to my fiendish little bomb. You have 6 phases with
which to blow yourself up. Have a nice day!

➜  lab gdb ./bomb
