Hi All:

Has anyone used the webkit SDK, carbon and Codewarrior 8.3? I'm getting
compile errors like:

Error : protocol 'WebDocumentView' redefined
(included from:
WebKit.h:14
CarbonUtils.h:11
main.c:1)
WebFrameView.h line 14 @protocol WebDocumentView;

Error : declaration syntax error
(included from:
WebKit.h:14
CarbonUtils.h:11
main.c:1)
WebFrameView.h line 19 @interface WebFrameView : NSView

Error : declaration syntax error
(included from:
WebKit.h:14
CarbonUtils.h:11
main.c:1)
WebFrameView.h line 20 {

Error : declaration syntax error
(included from:
WebKit.h:14
CarbonUtils.h:11
main.c:1)
WebFrameView.h line 21 @private

Error : declaration syntax error
(included from:
WebKit.h:14
CarbonUtils.h:11
main.c:1)
WebFrameView.h line 23 }

All I'm including is Webkit/CarbonUtils.h, it contains loading carbon
and cocoa. Am I missing an include or project setting? (I've turned on
Objective C).

Any hints?

Thanks

You are having header problems. Make sure you properly install the latest
Apple SDK and make sure CodeWarrior knows where they are. Also, make sure
you recompile all precompiled headers for your project.

Bob:

I didn't have any sort of prerelease version of Webkit on my computer,
and installed the release version. Codewarrior appears to know where to
get the files, the frameworks directory is in the access paths 'tab'.
I'll recompile the headers and see what happens.

Thanks for your time

John

Bob:

I rebuilt the libraries with the "Buildlibraries" project and it did do
the Mac OS X libraries, but after that, I'm still getting the
redefinitions.

Any ideas?

John

Have you tried starting from CW's Cocoa stationary project, and just
adding the Webkit stuff?

I haven't tried it, but does CodeWarrior have trouble with forward
declarations of protocols? I vaguely recall reading somewhere that it
might.

I don't know a thing about WebKit, but if you can #include the file that
defines WebDocumentView before you #include WebKit/CarbonUtils.h, that
might fix it.

I get the same error when trying to compile the SimpleCarbonWeb example.

The protocol WebDocumentView is defined on line 17 in WebDocument.h.
Then a forward reference to the protocol is made on line 14 of WebKit.h.

I believe the CW++ compiler is failing to honor the forward protocol
statement. You can read all about protocol statements at the apple web
site. The URL is
http://developer.apple.com/documentation/Cocoa/Conceptual/ObjectiveC/3obj
c_language_overview/index.html

In case MWRon reads this...
Any chance in getting this bug fixed in CW 8.3?
Will filing a bug report help getting this bug prioritized?

This bug makes it very difficult to work with the WebKit framework in a
CW project.

It sounds like this is being defined in two different files webKit. h
and CarbonUtils.h and they define it differently Look at the headers
and see what they have there.

Somewhere, perhaps in a precompiled header, you are also including
WebKit.h
