Hi All When I tried to build webkit on win7, I ran into the following problems: " ..\..\wtf\FastMalloc.cpp(83) : fatal error C1083: Cannot open include file: 'pthread.h': No such file or directory 2>c:\WebKit\Source\JavaScriptCore\wtf/unicode/icu/UnicodeIcu.h(27) : fatal error C1083: Cannot open include file: 'unicode/uchar.h': No such file or directory 2>MainThreadWin.cpp 2>TCSystemAlloc.cpp 2>RandomNumber.cpp 2>dtoa.cpp 2>c:\WebKit\Source\JavaScriptCore\wtf/unicode/icu/UnicodeIcu.h(27) : fatal error C1083: Cannot open include file: 'unicode/uchar.h': No such file or directory " It seems that pthread is supported by mingw in windows and I have mingw installed when I installed cygwin with default option. Any help? thanks Wu
