Compile Errors with Wallet Creation

[ZipperJacob]

Hello to all of the dedicated C++ programmers out there. I am really new to C++, but I decided to use a comprehensive guide to make an alternate cryptocurrency. I finished the new altcoin, but am having a lot of trouble with building the Mac OSX wallet. The code for the file with the compile error is here:

#include "macdockiconhandler.h"

#include <QtGui/QMenu>
#include <QtGui/QWidget>

extern void qt_mac_set_dock_menu(QMenu*);

#undef slots
#include <Cocoa/Cocoa.h>

@interface DockIconClickEventHandler : NSObject
{
MacDockIconHandler* dockIconHandler;
}

@end

@implementation DockIconClickEventHandler

- (id)initWithDockIconHandler:(MacDockIconHandler *)aDockIconHandler
{
self = [super init];
if (self) {
dockIconHandler = aDockIconHandler;

[[NSAppleEventManager sharedAppleEventManager]
setEventHandler:self
andSelector:@selector(handleDockClickEvent:withReplyEvent:)
forEventClass:kCoreEventClass
andEventID:kAEReopenApplication];
}
return self;
}

- (void)handleDockClickEvent:(NSAppleEventDescriptor*)event withReplyEvent:(NSAppleEventDescriptor*)replyEvent
{
Q_UNUSED(event)
Q_UNUSED(replyEvent)

if (dockIconHandler)
dockIconHandler->handleDockIconClickEvent();
}

@end

MacDockIconHandler::MacDockIconHandler() : QObject()
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
this->m_dockIconClickEventHandler = [[DockIconClickEventHandler alloc] initWithDockIconHandler:this];

this->m_dummyWidget = new QWidget();
this->m_dockMenu = new QMenu(this->m_dummyWidget);
qt_mac_set_dock_menu(this->m_dockMenu);
[pool release];
}

MacDockIconHandler::~MacDockIconHandler()
{
[this->m_dockIconClickEventHandler release];
delete this->m_dummyWidget;
}

QMenu *MacDockIconHandler::dockMenu()
{
return this->m_dockMenu;
}

void MacDockIconHandler::setIcon(const QIcon &icon)
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSImage *image;
if (icon.isNull())
image = [[NSImage imageNamed:@"NSApplicationIcon"] retain];
else {
QSize size = icon.actualSize(QSize(128, 128));
QPixmap pixmap = icon.pixmap(size);
CGImageRef cgImage = pixmap.toMacCGImageRef();
image = [[NSImage alloc] initWithCGImage:cgImage size:NSZeroSize];
CFRelease(cgImage);
}

[NSApp setApplicationIconImage:image];
[image release];
[pool release];
}

MacDockIconHandler *MacDockIconHandler::instance()
{
static MacDockIconHandler *s_instance = NULL;
if (!s_instance)
s_instance = new MacDockIconHandler();
return s_instance;
}

void MacDockIconHandler::handleDockIconClickEvent()
{
emit this->dockIconClicked();
}




After I try to make the wallet, I get these compile errors:

src/qt/macdockiconhandler.mm:50:39: error: assigning to 'objc_object *' from
incompatible type 'DockIconClickEventHandler *'
...= [[DockIconClickEventHandler alloc] initWithDockIconHandler:this];
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/qt/macdockiconhandler.mm:60:6: warning: receiver type 'objc_object *' is not
'id' or interface pointer, consider casting it to 'id' [-Wreceiver-expr]
[this->m_dockIconClickEventHandler release];
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

If anybody could help, that would be amazing.
