Alex, As to <mx:Application>, please forget it since I copied the wrong version (Apache Flex NOT Apache Royale). Sorry.
I run the following command on my Mac from the directory where Welcome.mxml is put. The result is the same as Windows 10. No index.html is generated. (And no error message) /Users/taksho/Downloads/apache-royale-0.9.6-bin-js/royale-asjs/js/bin/mxmlc +configname=flex -debug Welcome.mxml ----------------------- Welcome.mxml ----------------------- <?xml version="1.0"?> <mx:Module xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:mx="library://ns.apache.org/royale/mx" xmlns:s="library://ns.apache.org/royale/spark" paddingBottom="0" paddingTop="0" paddingLeft="0" paddingRight="0" height="100%" width="100%"> <mx:Panel title="Welcome to Tour De Flex (Apache Royale version)" paddingBottom="10" paddingTop="10" paddingLeft="10" paddingRight="10" height="100%" width="100%"> <s:HGroup> <s:Image source="mx/controls/assets/ApacheFlexLogo.png" width="50" height="50" /> <s:VGroup height="100%" verticalAlign="middle"> <s:Label text="Apache Tour De Flex" fontSize="20" fontWeight="bold" /> </s:VGroup> </s:HGroup> <s:RichText width="100%" height="100%"> <s:p /> <s:p>The Apache Flex Tour De Flex component explorer provides a sample set of working Apache Flex examples.</s:p> <s:p /> <s:p>New in this version:</s:p> <s:list> <s:li>Added this welcome page</s:li> <s:li>Changed examples look and feel to be more consistent</s:li> <s:li>Added support for 3rd party examples</s:li> <s:li>Added Squiggly spelling engine examples</s:li> </s:list> <s:p /> <s:p>For a full list of changes please see the README.</s:p> <s:p /> </s:RichText> </mx:Panel> </mx:Module> -- Sent from: http://apache-royale-users.20374.n8.nabble.com/
