GRRLib Forum / [RESOLVED] Make Error with GRRLIB

Hello.

Anyway, I'm having making my project with GRRLIB because I get these errors after using the make command:

Code:

Even though I have GRRLIB included.

Does anyone know why I'm getting these errors?

If you need my original code I'll upload/post it on request.

Thanks a lot. It compiles now, and I've been trying to get it to work for a few days now. I guess next time I'll search.

Also, I have another problem. My Wii freezes up after drawing an image because after the image is displayed I hit HOME and nothing
happens.

Here's where it freezes up:

Code:

//>>>>>>>>>>>>>>>>>>>>>START BELOW:>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

        GRRLIB_DrawImg(0, 0, tex_menu, 0, 1, 1, 0xFFFFFFFF);
        
        GRRLIB_Render();                      //For GRRLIB
        
        while(1)
        {
            if ( pressed1 & WPAD_BUTTON_HOME )    //Go home!
            {exit(0);}
        }

//>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Here's the whole code in case:

        VIDEO_WaitVSync();
    }
    
    GRRLIB_Exit(); // Be a good boy, clear the memory allocated by GRRLIB
    return 0;
}

I searched the forums, but couldn't find anything specifically relating to this.

Thanks a lot for the help, and you'll probably be hearing a lot from me (but hopefully not), but thanks again,

three things,

first, please refere to sample code provided with grrlib, there is no need to define xfb, and other video stuff, grrlib_init, do all this !! in other words, startmii is very useless (except for wpad initialisation), and can provide your problem. USE the TEMPLATE provided code to start your project....

second, i advise you to use the SVN version ( we change a lot of thing)
http://code.google.com/p/grrlib/source/checkout

third, have a look at sample code, (svn or not) there is a way to free texture.

tell us if it correct your probleme

TPAINROXX · 2009-06-16 04:21:50

Alright I done a quick test with displaying the menu and it worked fine. I'm going to try to fix tonight and tomorrow and see if I can get the basic thing running.

Thanks a lot for the help because I would have never known to do some of what you told me. I realize some of it was noobish, but thanks.

I have no problems as of now and WiiMoveIt is on its way...

And... one more thing (a quick general code related question):

If I were to hit HOME then why do I need to include GRRLIB_Exit(); and free(whatever.data); because wouldn't exit(0); mean to end the program there? Or does it complete the program and execute only certain functions? I know this somewhat isn't GRRLIB related, but thanks and sorry for the dumb questions.

This was from:

Code:

while(1)
        {
            if ( pressed1 & WPAD_BUTTON_HOME )    //Go home!
            {exit(0);}
        }

//>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

        // Wait for the next frame
        VIDEO_WaitVSync();
    }
    
    GRRLIB_Exit(); // Be a good boy, clear the memory allocated by GRRLIB
    return 0;

On the Wii I think you don't to free the memory, but if you ever program for an other system, be sure to do it. I think GRRLIB_Exit is making sure that next time an app is loaded the screen will appear black for the couple of milliseconds before the app draw on the screen.

In your code instead of exit(0) just put a break; to exit the while loop.
If you use GRRLIB never use VIDEO_* functions in your code.

TPAINROXX · 2009-06-18 02:20:50

Thanks for that I forgot to remove that when I removed the other Video related functions.

You and NoNameNo are very helpful, so thanks for the help.

If you want it to wait for user input in the inner while you still need to update pressed1.

Code:

while(1)
        {
            pressed1  = WPAD_ButtonsDown(0);

            if ( pressed1 & WPAD_BUTTON_HOME )    //Go home!
            {exit(0);}
        }

or just remove the while around this section

In my current code I've removed any

Code:

pressed1  = WPAD_ButtonsDown(0);

and now I just use:

Code:

if (WPAD_ButtonsDown(0))
{//blah}

,but thanks.
