Description Christoph Feck 2012-11-07 22:14:24 UTC 
If this is a cmake bug, please resolve as downstream.

After update from cmake 2.8.9 to 2.8.10, compiling master:

Comment 1 Harald Sitter 2012-11-08 09:30:25 UTC 
Can't reproduce this with their 2.8.10.1 static binary.

Also with Qt 4.8.1 I have...

mediaelement.h:55:    Q_INTERFACES(QDeclarativeParserStatus)

mediaelement.h:26:#include <QtDeclarative/QDeclarativeItem>

QtDeclarative/QDeclarativeItem:1:#include "qdeclarativeitem.h"

QtDeclarative/qdeclarativeitem.h:46:#include <QtDeclarative/qdeclarativeparserstatus.h>

QtDeclarative/qdeclarativeparserstatus.h:69:Q_DECLARE_INTERFACE(QDeclarativeParserStatus, "com.trolltech.qml.QDeclarativeParserStatus")
Comment 2 Christoph Feck 2012-11-08 12:11:33 UTC 
> QtDeclarative/qdeclarativeitem.h:46:#include <QtDeclarative/qdeclarativeparserstatus.h>

There's the problem, the Qt 4.8.3 header does not include this one.

I tried with 2.8.10.1 again, and got the same error.

Pushed by sitter into branch 'master'.

fix declarative stuff with qt 4.8.3

apparently it is now acceptable to move include statements around

M  +1    -0    declarative/mediaelement.h
M  +1    -0    declarative/videooutputelement.h

Comment 4 Christoph Feck 2012-11-08 13:05:51 UTC 
Unfortunately, this does not fix it :/ Going back to cmake 2.8.9 it works.
Comment 5 Harald Sitter 2012-11-08 13:13:25 UTC 
Oo

please check that the interface is declared in QtDeclarative/qdeclarativeparserstatus.h and if so I am reasonable confident that cmake has a bug
Comment 6 Christoph Feck 2012-11-08 13:20:33 UTC 
Yes, it's there. I am going to report it to cmake developers.
