最近见 Qt5 的 Beta 版发布了，就拖下来编译看看。在散热奇差的古董笔记本上执行编译，实在是历尽磨难，多天之后才完成任务。可惜WebKit库生成没有成功，暂时无法使用。
首先编译前需要准备 perl 和 python。python 还好，之前装了python2.7版本。perl 版本有点旧，只是 5.6，文档里要求是5.12以上。这点就挺折磨人的。
先是尝试，dirname 通不过，正则中有 \h 也通不过，无奈升级至 ActivePerl 5.14，然后继续。
总是开启编译流程，古董笔记本被整强制关机了好多次。明明是单进程编译，偏偏整出这么多的nmake。
到了 QtWebKit 部分提示需要 ICU。
1 Project ERROR: To build QtWebKit with Qt 5 you need ICU 2 NMAKE : fatal error U1077: 'cd' : return code '0x2' 3 Stop. 4 NMAKE : fatal error U1077: 'D:\Progs\VS9\VC\BIN\nmake.exe' : return code '0x2' 5 Stop. 6 NMAKE : fatal error U1077: 'cd' : return code '0x2' 7 Stop. 8 NMAKE : fatal error U1077: 'D:\Progs\VS9\VC\BIN\nmake.exe' : return code '0x2' 9 Stop. 10 NMAKE : fatal error U1077: '(' : return code '0x2' 11 Stop.
那就下载最新版本的ICU4.9，需要cygwin才能用 VC2008来编译，没有cygwin，多方尝试无果。选择ICU4.4版本来继续。
设置 PATH、INCLUDE、LIB，依然提示错误，应该是 configure 时没有找到吧，直接把检查的语句注释掉后继续。
话说WebKit 实在是奇葩啊，一个 lib 文件居然整了600+M，不可思议。
最后链接生成DLL，居然找不到各种来自WebCore Symbols，实在无语。其实因为 configure 时没有加 -icu 选项，导致没有将 TextBreakIteratorICU.cpp 文件加入到 Makefile 中而出错。可以删除已生成的 Makefile 文件，只重新编译一下 Webkit 部分代码即可。至此，编译总算告一段落。
