Unresolved entry point: MAMain

Hi,

Try creating a new project using Wizard. Then, compare the new one with this.

Regards,

Diego

What should it do?

If you're working off MAUIex, then deleting main.cpp will also delete the MAmain() function, so I'm not surprised your getting that message. In C and C++, all programs start by running a function called 'main'. In MoSync, this is actually called MAMain. In MAMain it creates and runs an instance of the Moblet object. The moblet constructor has a line like:

MainScreen* mainScreen = new MainScreen();
mainScreen->show();

You need to replace these lines with ones which show your screen.

Sam,

don't forget the debugger problem. If you place a breakpoint and then edit the code, sometimes it runs the app and exits. Insert, try removing all breakpoints.

I think we probably need to see the contents of your main.cpp. Can you paste the source into here? What you should probably have is a file called main.cpp which has a function called MAMain() which looks something like this:

extern "C" int MAMain()
{
	Moblet::run(new MyMoblet());
	return 0;
};

Which will start your app, and your Moblet code will create and show the first screen

MyMoblet::MyMoblet()
{
  Screen* myScreen = new MyScreen();
  myScreen->show();
}

Hi Diego,

I was reading this conversation today and found your aforementioned comment. Interesting, would you like to explain it a bit more. I am already trying to reproduce and look into it. Our utmost desire it to provide you guys with a bug-free debugger. And for that, we for sure require your help. Provide me with some more details if you can and we will try to fix it asap.

Enjoy a nice summer.

Hey workhard, I'm not sure why you've posted this code? Are you having this problem? If so, then there are two things you need to do - have a file called main.cpp with a method called MAMain(). All MoSync programs start by calling MAMain(), always.

extern "C" int MAMain()
{
    Moblet::run(new QuizMoblet());
    return 0;
};

Secondly, you don't need to make QuizMoblet a singleton, the Moblet::run static method will invoke a single instance of the moblet and execute the constructor.

hello sam, i create a main.cpp and input the following code u given me above it does not work saying " QuizMoblet has not been declared "

i put the code in the QuizMoblet.cpp because i do not have a main.cpp and i create one but it will show the same error as QuizMoblet

To verify iszit always a moblet file ( file that contain moblet ) that is the first page of the program? because that when u input MAMain() which run always at the first place when the program run?

Hi workhard, moblet is one way of creating an app in MoSync. If you are using C++, then it is definitely the recommended option as there are a lot of work done handing device resources.

If you are writing in C, then you don't have to use moblet at all.
Either way (in C or C++) you need an MAMain() function. For your quiz app, you need to create the MAMain() function to create the moblet.

It sounds like you need to add the headers for QuizMoblet to the main.cpp file.

#include <MAUtil/Moblet.h>
#include "QuizMoblet.h"
using namespace MAUtil;
extern "C" int MAMain()
{
    Moblet::run(new QuizMoblet());
    return 0;
};

hi sam , after adding the codes u given me to the main.cpp

i still having the same error

'QuizMoblet' has not been declared .
