sudo apt-get install libc6-dev-i386
sudo apt-get install lib32z1

带gdb调试bochs

sudo apt install build-essential libx11-dev libxrandr-dev libsdl1.2-dev vgabios bximage

安装脚本：进入bochs目录执行即可

#!/bin/bash
./configure --enable-debugger --enable-readline
make -j8
sudo make install
sudo mv `which bochs` `which bochs`dbg
./configure --enable-gdb-stub
make -j8
sudo make install

bochsrc脚本配置：

# enable gdb debug
gdbstub: enabled = 1, port = 1234, text_base = 0, data_base = 0, bss_base = 0
