Can't compile the Qutlook example

Printable View

Hello,

I use the Qt 4.3.1 commercial edition for Windows, and I want to test the ActiveQt example : "Qutlook".

Unfortunately, during the compilation of this example, I get the following errors :

Code:

mingw32-make all 
mingw32-make -f Makefile.Release all

Does anyone have the same problem as me when compiling this example?

Thanks for your help.

Re: Can't compile the Qutlook example

I suggest you report that to Trolltech using the task-tracker.

Re: Can't compile the Qutlook example

I have the same problem, 3 years after.
But I don't see any similar problems on the net.
Then I am in doubt with the usage of this functionality.

Re: Can't compile the Qutlook example
I have found a solution !

"Enums cannot be forward declared. First of all the C++ standard does not define forward declaration. It defines incomplete types." (from http://bytes.com/topic/c/answers/622...claration-enum)

So, gcc/mingw is right, and doesn't compile this source.
It is a bug, perhaps in the msoutl.olb file, perhaps in the dumpcpp tool (I don't know why, but I think it is from the olb file)

If you don't intend to use this enum, you can easily define it BEFORE the inclusion of the msoutl.h file, like this:
Code:

namespace Office { enum MsoFeatureInstall { value }; } //! [0] #include "addressview.h" #include "msoutl.h" #include <QtGui> ....
Yours, J..

Re: Can't compile the Qutlook example

I don't know why it worked; it didn't recompile the msoutl.cpp, but it is not correct and doesn't work.
I think it is a bug in the dumpcpp tool, and opened a bug in their bug tracking tool: http://bugreports.qt.nokia.com/browse/QTBUG-11721

So, no resolution, for yet.

Re: Can't compile the Qutlook example

Hi guys. You are quite correct. Enums can not be passed from COM server. All data is via class declarations. The problem is caused by -gccdump incorrectly creating msoutl.h, but the answer is simple.
Open msoutl.h in editor and change line - "enum MsoFeatureInstall;" - to "class MsoFeatureInstall;"

#include <qdatetime.h>
#include <qpixmap.h>

struct IDispatch;

// Referenced namespace
namespace Office {
class Assistant;
class COMAddIns;
class LanguageSettings;
class AnswerWizard;
class MsoFeatureInstall; *** changed from - enum MsoFeatureInstall;
class CommandBars;
}

Re: Can't compile the Qutlook example

Sorry guys

First assumptions not quite right. Enum is required and needs to be declared prior to forward declaration. Try this. It does compile now.

// Referenced namespace
namespace Office {

enum MsoFeatureInstall {
msoFeatureInstallNone = 0,
msoFeatureInstallOnDemand = 1,
msoFeatureinstallOnDemandWithUI = 2
};

// forward declarations
class Assistant;
class COMAddIns;
class LanguageSettings;
class AnswerWizard;
enum MsoFeatureInstall;
class CommandBars;
}
