告诉你Ubuntu安装Bochs过程中遇到的问题及解决方法及命令

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.gz
cd 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...  X11
Package 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 variable
No package 'gtk+-2.0' found
ERROR: 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 1
make[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

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。
