Hi, I have tried to build webkit on Windows and have no luck so far. It looks like there are 3 missing header files: 'unicode/pwin32.h', 'pthread.h' and 'JSDOMExceptionConstructor.lut.h' Here is my BuildLog: Constructing generated files...Copying ICU DLLS... Compiling...c_utility.cppF:\cygwin\home\yshih\WebKit\JavaScriptCore\icu\unicode/umachine.h(45) : fatal error C1083: Cannot open include file: 'unicode/pwin32.h': No such file or directorystring_object.cppF:\cygwin\home\yshih\WebKit\JavaScriptCore\icu\unicode/umachine.h(45) : fatal error C1083: Cannot open include file: 'unicode/pwin32.h': No such file or directorylexer.cppF:\cygwin\home\yshih\WebKit\JavaScriptCore\icu\unicode/umachine.h(45) : fatal error C1083: Cannot open include file: 'unicode/pwin32.h': No such file or directoryJSLock.cpp..\..\kjs\JSLock.cpp(28) : fatal error C1083: Cannot open include file: 'pthread.h': No such file or directoryfunction.cppF:\cygwin\home\yshih\WebKit\JavaScriptCore\icu\unicode/umachine.h(45) : fatal error C1083: Cannot open include file: 'unicode/pwin32.h': No such file or directorycollector.cpp..\..\kjs\collector.cpp(36) : fatal error C1083: Cannot open include file: 'pthread.h': No such file or directory Build log was saved at "file://F:\cygwin\home\yshih\WebKit\WebKitBuild\obj\JavaScriptCore\Release\BuildLog.htm"JavaScriptCore - 6 error(s), 0 warning(s) Performing Pre-Build Event...cl : Command line warning D9040 : ignoring option '/analyze'; Code Analysis warnings are not available in this edition of the compilertmp.cppmake: *** No rule to make target `JSDOMExceptionConstructor.lut.h', needed by `all'.
