webkit是一个浏览器内核，google的chrome就是基于它的，下面介绍一下如何在Ubuntu 11.04下编译Webkit源代码。网上有大量的关于如何在Windows下或者如何用Qt来编译Webkit，本文不对此进行介绍，只介绍如何在命令行下编译Webkit源代码：
1.下载：在http://nightly.webkit.org/ 下载webkit的最新版本源码，我的是WebKit-r96832
2.编译：
./WebKit-r96832/Tools/Scripts/build-webkit --gtk
正常情况下会缺少各种库，没关系，一个一个解决。下面列举了我所遇到的一些问题：
sudo apt-get install libtool
sudo apt-get install gtk-doc-tools
错误：undefined macro XXX （不记得了）
解决：sudo apt-get install libgtkhtml* （全部安装）
错误：configure: error: JPEG library (libjpeg) not found
解决：sudo apt-get install libjpeg8-dev （当时我编译的时候libjpeg的最新版是8，你编译的时候要选择当前的最新版，下同！）
错误：Cannot find icu-config. The ICU library is needed.
解决：sudo apt-get install libicu-dev
错误：configure: error: Package requirements (gail-3.0 >= 3.0) were not met: No package 'gail-3.0' found
解决：sudo apt-get install libgail-3-dev
错误：configure: error: X Toolkit Intrinsics library (libXt) not found
解决：sudo apt-get install libxt-dev
错误：configure: error: Package requirements (libsoup-2.4 >= 2.33.6) were not met: No package 'libsoup-2.4' found
解决：sudo apt-get install libsoup2.4-dev
错误：configure: error: SQLite3 is required for the Database related features
解决：sudo apt-get install libsqlite3-dev
错误：configure: error: Package requirements (libxslt >= 1.1.7) were not met: No package 'libxslt' found
解决：sudo apt-get install libxslt-dev
错误：configure: error: Package requirements (geoclue) were not met: No package 'geoclue' found
解决：sudo apt-get install libgeoclue-dev
错误：configure: error: Package requirements (gstreamer-0.10 >= 0.10
gstreamer-app-0.10
gstreamer-base-0.10
gstreamer-interfaces-0.10
gstreamer-pbutils-0.10
gstreamer-plugins-base-0.10 >= 0.10.30
gstreamer-video-0.10) were not met:
No package 'gstreamer-0.10' found
No package 'gstreamer-app-0.10' found
No package 'gstreamer-base-0.10' found
No package 'gstreamer-interfaces-0.10' found
No package 'gstreamer-pbutils-0.10' found
No package 'gstreamer-plugins-base-0.10' found
No package 'gstreamer-video-0.10' found
解决：sudo apt-get install libgstreamer*
最后终于没有问题，开始编译了！
./WebKit-r96832/Tools/Scripts/build-webkit --gtk
经过了漫长的等待（整整一个小时！），终于编译通过了！
记录一下编译通过的输出：
WebKit is now built (1h:01m:41s).
To run GtkLauncher with this newly-built code, use the
"Tools/Scripts/run-launcher" script.
如何运行？
./Tools/Scripts/run-launcher --gtk 就可以啦！
完成！
