ubuntu 12.04 LTS 安装可调试bochs 2.6

ubuntu 12.04 LTS 安装可调试bochs 2.6

最近一直在看于渊的<<ORANGE'S 一个操作系统的实现>>对于环境的搭配十分困扰。经过不停得测试实验最后终于成功，现将心得分享，也为以后自己再次搭配留下资料。

___________________________________________________

如果有任何问题，请重启后再次尝试，不要轻易放弃。可以设置

snapshot还原点达到备份和快速启动的效果

1.首先安装ubuntu12.04(官网下32位），vmware安装后，下载bochs2.6(最新版）,注意linux下的文档应该是bochs-2.6.tar.gz.

2.接下来搭配GUI $sudo apt-get install xorg-dev

3.然后是$sudo apt-get install libgtk2.0-dev

4.cpp g++ gcc 编译环境也是必不可少的$sudo apt-get install gcc cpp g++
5.解压缩$bochs 2.6.tar.gz tar vxzf bochs-2.6.tar.gz

6. 进入bochs 2.6文件夹后 $./configure --enable-debugger --enable-disasm(安装dubugger调试和反汇编)

7.$sudo make (不用make不是root会报权限错误）

8.接下来$sudo make install

如果没什么错就安装完成了，接下来哦就是配置启动文件了,由于《一个操作系统的实现》是旧版本，所以我们需要修改配置的一些设置

romimage: file=usr/share/bochs/BIOS-bochs-latest 改为 romimage: file=/usr

/local/share/bochs/BIOS-bochs-latest

vgaromimage: file=/usr/share/vgabios/vgabios.bin改为vgaromimage: file=/usr/local/share/bochs/VGABIOS-lgpl-latest

同理在最后哪一行的鼠标设置中也添加/local这个路径

————————————————————————————

接下来就是启动了，$bochs -f bochsrc

Please choose one[6]:$6

直接c便可看到效果

如果要调试请按此下步骤
