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.
Comment 3 Harald Sitter 2012-11-08 12:37:17 UTC 
Git commit f8701371ceb2773ef9d76846532ddf8bef92771c by Harald Sitter.

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.
