在windows下编译webkit

•

这是半年前在windows上编译、调试webkit的一些记录，可能比较乱。

windows下的webkit apple port编译的经验总结

  1. 主要参考webkit官网，在不清楚文档中每一步的作用前，老老实实的按照文档做
  2. 安装cygwin的时候要选择install from local directory， 否则会缺失包
  3. 在WebKitLibraries/win/tools/vsprops目录下面手动建立一个.svn文件夹（可以通过命令行建立）
  4. BuildLog是很好的参考资料，一旦出错，参考该log是比较容易找出问题的
  5. build-webkit 和 通过 vs编译事实上是一样的，因为build-webkit调用的是就是vs的命令行
  6. 另外dumprendertree 还是必须将vs编译的选项 treat warning as error改成 no，否则无法编译通过
  7. 在编译时还遇到一个问题，就是cl.exe报fatal错误，查了相关资料，后来没做任何处理，重新编译就可以了
debug调试
用safari作为debug总是会出错，以下为错误信息：
Unhandled exception at 0x78145215 (msvcr80.dll) in Safari.exe: 0xC0000005: Access violation reading location 0x091bfffc.
memcpy(data, characters, length * sizeof(UChar));
+ dst 0x091c0034 "" unsigned char *
+ src 0x089e9b10 ",甓" unsigned char *
count 68945734 unsigned long
memcpy(data, characters, length * sizeof(UChar));
+ data 0x091c0034 "" wchar_t *
+ characters 0x089e9b10 "Ҷ" const wchar_t *
length 34472867 unsigned int
+ string {m_ptr=0x091c0020 } WTF::PassRefPtr<WTF::StringImpl>
后来使用winLancher作为debug的工具，还是不错的。
或者使用minibrowser作为debug的工具，需要主要的是，minibrowser要attach到webkit2的进程上面
运行这个需要apple的相关dll，这些dll的位置在 C:\Program Files\Common Files\Apple\Apple Application Support
注意，不要把webkit javascriptcore相关文件复制过去。
