学习操作系统，下载了bochs最新版本，但是不会编译安装，老是出错，用了一会简单的无调试功能的bochs但是感觉缺少点什么，，想用带调试功能的，网上搜索了好多资料，终于自己完成了编译安装的bochs，不容易啊，赶紧分享一下，linux版本是Ubuntu 9.04 虚拟己版本是bochs 2.4.1
不带调试功能的简单安装方法:sudo apt-get install bochs
带调试功能的bochs安装
sudo apt-get install build-essential 安装编译环境
tar vxzf bochs-2.4.1.tar.gzcd bochs-2.3.5./configure –enable-debugger –enable-disasm这一步问题出来了，没注意配置时出现的问题就接着make了，导致make的时候，老是说83行遗漏分隔符。后来注意到了configure 的时候最后一行出现了一句：
> ERROR: X windows gui was selected, but X windows libraries were not found.
后来解决了，sudo aptitude install xorg-dev
When install bochs, While I compile come file with ./configure there give a msg:
> configure: WARNING: Bochs for wxWidgets cannot be compiled here, disabling it
> checking for default gui on this platform… x11
> ERROR: X windows gui was selected, but X windows libraries were not found.
I just follow this :
You need to install the development libraries. To compile a wxWidgets
program you need libwxbase2.4-dev, libwxbase2.4-dev, and
libwxgtk2.4-contrib-dev (for a wx2.4 program) or libwxgtk2.6-dev (for a
wx2.6 program). For an X11 program you need x-window-system-dev, which
should pull in all the dependencies you need.
but I couldn’t install the x-window-system-dev with: sudo apt-get install x-window-system-dev
the to solved this just:
sudo aptitude install xorg-dev everything is fine with the ./configure now .
sudo apt-get install xorg-dev无法安装，吼吼，又学到了个aptitude 。
再./configure 试试，晕，又有错误，错误提示是checking for display libraries… X11Package gtk+-2.0 was not found in the pkg-config search path.Perhaps you should add the directory containing `gtk+-2.0.pc’to the PKG_CONFIG_PATH environment variableNo package ‘gtk+-2.0’ foundERROR: pkg-config was not found, or unable to access the gtk+-2.0 package.Install pkg-config and the gtk+ development package,or disable the gui debugger, or the wxWidgets display library (whichever is being used).
这个安装了个 gtk就解决了 sudo aptitude install libgtk2.0-dev (这个是自己猜的，安装上果然可以了，呵呵，还有点天分)
然后make，make 的时候也出了点问题。proc_ctrl.cc:654: 错误： ‘CheckPDPTR’在此作用域中尚未声明proc_ctrl.cc:668: 错误： ‘CheckPDPTR’在此作用域中尚未声明make[1]: *** [proc_ctrl.o] 错误 1make[1]:正在离开目录 `/media/disk-1/Linux/bochs-2.4.1/cpu’make: *** [cpu/libcpu.a] 错误 2
上网搜的是那个文件出了错proc_ctrl.cc
make时的错误proc_ctrl.cc:654: error: ‘CheckPDPTR’ was not declared in this scope proc_ctrl.cc:668: error: ‘CheckPDPTR’ was not declared in this scope make[1]: *** [proc_ctrl.o] Error 1
GCC版本gcc (Ubuntu 4.3.3-5ubuntu4) 4.3.3
自己解决:

问题6： install: 无法获取”./bochsdbg” 的文件状态(stat): 没有该文件或目录
解决办法：需要在make后，将bochs拷贝一份，命名为bochsdbg
make问题解决了，然后sudo make install 就可以了
