學習操作系統，下載了bochs最新版本，但是不會編譯安裝，老是出錯，用了一會簡單的無調試功能的bochs但是感覺缺少點什麼，想用帶調試功能的，網上搜索了好多資料，終於自己完成了編譯安裝的bochs，不容易啊，趕緊分享一下，linux版本是Ubuntu 9.04 虛擬己版本是bochs 2.4.1
不帶調試功能的簡單安裝方法:
sudo apt-get install bochs
帶調試功能的bochs安裝
sudo apt-get install build-essential 安裝編譯環境
tar vxzf bochs-2.4.1.tar.gz
cd bochs-2.3.5
./configure --enable-debugger --enable-disasm
這一步問題出來了，沒注意配置時出現的問題就接著make了，導致make的時候，老是說83行遺漏分隔符。後來注意到了configure 的時候最後一行出現了一句：
> ERROR: X windows gui was selected, but X windows libraries were not found.
後來解決了，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無法安裝，吼吼，又學到了個aptitude 。
再./configure 試試，暈，又有錯誤，錯誤提示是
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).
這個安裝了個 gtk就解決了
sudo aptitude install libgtk2.0-dev (這個是自己猜的，安裝上果然可以了，呵呵，還有點天分)
然後make，make 的時候也出了點問題。

問題6：
install: 無法獲取"./bochsdbg" 的文件狀態(stat): 沒有該文件或目錄
解決辦法：需要在make後，將bochs拷貝一份，命名為bochsdbg
make問題解決了，然後
sudo make install 就可以了
