I get following ouput Output Window Performing Pre-Build Event... /usr/bin/bash 复制了 0 个文件 Compiling...

Thanks very much.
I'm surprised that this didn't come up before. People have fixed similar issues in WebKit code (see e.g. bug 23598), but not in ConditionalMacros.h.
thank you, and could you tell me how I can past this error?

(In reply to comment #2) > thank you, and could you tell me how I can past this error? You could remove the offending characters from your local copy of ConditionalMacros.h.
I opened ConditionalMacros.h in Microsoft Visual C++ 2005 Express Edition and saved it, then rebuild it. it works well. thank you all!
