出发点： 我想看免费的国内外网络电视，所以基于ARM板DIY一个Internet TV, 需要做的工作主要有：
1) 编译浏览器webkit
2) 移植clutter webkit实现类似apple界面
3) 移植Morphine.tv
实践过程：目前网络上交叉编译 webkit的方法主要是基于QT,DFB,GTK,考虑到基于GTK的开源应用丰富得多，目前很多有价值的开源应用都是基于X11的，出于这点考虑，决 定基于GTK交叉编译Webkit, 能google到的最流行的两篇交叉编译webkit的文章是http://ppbabytiger.spaces.live.com/blog/cns!549302309A9552BE!397.entry和http://blog.csdn.net/hou_jiong/archive/2009/01/18/3831022.aspx，但是基于这两篇文章我没有交叉编译成功，下面列出我基于X11编译webkit所依赖库的版本号：

if there are errors like “u_charType_3_6 undefined” , link the depend library via adding -licui18n to dependency_libs in WebKit-r29711/libJavaScriptCore.la file
dependency_libs=' -lpthread -licui18n '
实践结果：
由于webkit编译完后只产生一个动态库，需要再编译个带有操作界面的浏览器，源码和Makefile如下：
