笑翔

昨天在北京的UME看了《桃花运》，片子算不上新颖，但人生百味，悲喜哭笑尽现其中。“胖大姐”为了爱义无反顾，让常人感动，令浪子回头。x小露(?)处处为心爱的人着想，竭尽所能，甚至所不能！...

    During embedded R&D, there are many times we'd build cross-toolchain manually for the target platform. "Oh, no, that's a time-consuming job, and always company with strange errors", someone fears :P

    Now Linke Wang and I have wroten down all the steps in a script which, eventually, makes the job easier than talking with your girlfriend in MSN :)

    The toolchain generated by this script not only supports generic arm-linux, but also google's Andoird OS.

    In the coming logs, I'd like to explain the following script step by step for those interested.
