[webkit-dev] building errors about "cmd.exe"

[sitan2006 at sina.com]

Hi, I found a new clue which I think is the answer.
 
In jscCommon.vsprops, some shell commands about VS' post-build event:
 
************************************&nbsp;<Tool
&nbsp;&nbsp;Name="VCPostBuildEventTool"
&nbsp;&nbsp;CommandLine="if exist &quot;$(WebKitOutputDir)\buildfailed&quot; del &quot;$(WebKitOutputDir)\buildfailed&quot;&#x0D;&#x0A;&#x0D;&#x0A;mkdir 2&gt;NUL &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\icudt40.dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\icudt40.dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\icudt40$(LibraryConfigSuffix).dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\icudt40$(LibraryConfigSuffix).dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\icuin40$(LibraryConfigSuffix).dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\icuin40$(LibraryConfigSuffix).dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\icuuc40$(LibraryConfigSuffix).dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\icuuc40$(LibraryConfigSuffix).dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\CoreFoundation$(LibraryConfigSuffix).dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\CoreFoundation$(LibraryConfigSuffix).dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\CoreFoundation.resources&quot; xcopy /y /d /e /i &quot;$(WebKitLibrariesDir)\bin\CoreFoundation.resources&quot; &quot;$(WebKitOutputDir)\bin\CoreFoundation.resources&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\pthreadVC2$(LibraryConfigSuffix).dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\pthreadVC2$(LibraryConfigSuffix).dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;if exist &quot;$(WebKitLibrariesDir)\bin\objc$(LibraryConfigSuffix).dll&quot; xcopy /y /d &quot;$(WebKitLibrariesDir)\bin\objc$(LibraryConfigSuffix).dll&quot; &quot;$(WebKitOutputDir)\bin&quot;&#x0D;&#x0A;"

I checked the commands carefully,&nbsp; and found that there's no "bin/" under my "WebKitLibraries/win/", also in the orginal Webkit, WebKitAuxiliaryLib.zip and WebKitSupportLibrary.zip.
Of course, there's no "icudt40.dll" and other ".dll" files.
&nbsp;
Now I am quite sure that's the reason for "jsc failed".
&nbsp;
Well, what are these dll files for? Why there's no such files at all?

OK, it sounds like jsc.vcproj is failing but the other projects are 
succeeding. jsc.vcproj produces jsc.exe, which is a JavaScript 
interpreter. Having jsc.exe fail to build doesn't affect whether 
WebKit.dll builds (since WebKit.dll builds first).

Does the BuildLog.htm file for jsc.vcproj mention any errors? You can 
find it at WebKitBuild/obj/jsc/Release/BuildLog.htm.
