從零開始基於ARM 交叉編譯開源瀏覽器webkit
出發點： 我想看免費的國內外網路電視，所以基於ARM板DIY一個Internet TV, 需要做的工作主要有：
1) 編譯瀏覽器webkit
2) 移植clutter webkit實現類似apple介面
3) 移植Morphine.tv
設定環境變數和編譯配置

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 '
實踐結果：
由於webkit編譯完後只產生一個動態庫，需要再編譯個帶有操作介面的瀏覽器，原始碼和Makefile如下：
