Bug 24274 – [Qt] WebKit Qt build fails on Mac with Qt 4.4.2

• Component: WebKit Qt
• Status: RESOLVED FIXED

[Erik L. Bunce]

WebKit Qt build fails on Mac with Qt 4.4.2 built with:
$ ./WebKitTools/Scripts/build-webkit --qt  --debug 

The first failure is: 
../../../WebCore/platform/text/mac/StringImplMac.mm -o tmp/StringImplMac.o
../../../WebCore/platform/mac/FoundationExtras.h: In function ‘objc_object* HardRetain(objc_object*)’:
../../../WebCore/platform/mac/FoundationExtras.h:35: error: ‘CFRetain’ was not declared in this scope
../../../WebCore/platform/mac/FoundationExtras.h: In function ‘void HardRelease(objc_object*)’:
../../../WebCore/platform/mac/FoundationExtras.h:41: error: ‘CFRelease’ was not declared in this scope
../../../WebCore/platform/mac/FoundationExtras.h: In function ‘objc_object* HardRetainWithNSRelease(objc_object*)’:
../../../WebCore/platform/mac/FoundationExtras.h:57: warning: no ‘-release’ method found
../../../WebCore/platform/mac/FoundationExtras.h:57: warning: (Messages without a matching method signature
../../../WebCore/platform/mac/FoundationExtras.h:57: warning: will be assumed to return ‘id’ and accept
../../../WebCore/platform/mac/FoundationExtras.h:57: warning: ‘...’ as arguments.)
../../../WebCore/platform/mac/FoundationExtras.h: At global scope:
../../../WebCore/platform/mac/FoundationExtras.h:66: error: ‘HardAutorelease’ declared as an ‘inline’ variable
../../../WebCore/platform/mac/FoundationExtras.h:66: error: ‘CFTypeRef’ was not declared in this scope
../../../WebCore/platform/mac/FoundationExtras.h:67: error: expected ‘,’ or ‘;’ before ‘{’ token
../../../WebCore/platform/text/mac/StringImplMac.mm: In member function ‘WebCore::StringImpl::operator NSString*()’:
../../../WebCore/platform/text/mac/StringImplMac.mm:30: error: ‘HardAutorelease’ cannot be used as a function
make[1]: *** [tmp/StringImplMac.o] Error 1

This was caused by the migration by the Mac port to use FoundationExtras.h (which didn't include the <Foundation/Foundation.h> header).

After fixing that problem we get:
../../../WebCore/plugins/mac/PluginViewMac.cpp:
../../../WebCore/plugins/mac/PluginViewMac.cpp:72: error: ‘JSC::JSValue’ has not been declared
../../../WebCore/plugins/mac/PluginViewMac.cpp:79: error: ‘OSWindowRef’ does not name a type
make[1]: *** [tmp/PluginViewMac.o] Error 1

The JSC::JSValue error is caused by the in-progress migration through the new JSC::JSValuePtr rework.

The second is caused by the typedef being different between Qt 4.4.x (WindowPtr) and Qt 4.5 (OSWindowRef).

This was against svn r41344.

Fixed the Qt 4.4 Mac build with netscape plugins enabled.

WebCore/platform/mac/FoundationExtras.h was fixed by svn r41939.

Fixes the remaining Qt 4.4 issue.
Fixes the general compilation issue caused by the JSC::JSValuePtr transition.
