DI_Eject(); Not Working

[Ghost6765]

I tried the

Code: Select all

DI_Eject();

function on MSVC++ 2010 Express that got mentioned here : http://www.devkitpro.org/viewtopic.php?f=3&t=2103
but I keep getting this error:

	while(1) {

		WPAD_ScanPads();

		if ( pressed & WPAD_BUTTON_A ) DI_Eject(); 

		// Wait for the next frame
		VIDEO_WaitVSync();
		
		printf ("Welcome To My 2nd Wii Program");
		printf ("\n\nPress A To Eject");

  c:/devkitPro/examples/wii/Wii_Eject/source/main.c:58: warning: implicit declaration of function 'DI_Eject'

is caused by not using the right include. If you look in the libogc/include folder you'll find it at <di/di.h>

Code: Select all

  main.o: In function `main':
  c:/devkitPro/examples/wii/Wii_Eject/source/main.c:58: undefined reference to `DI_Eject'
  collect2: ld returned 1 exit status

is caused by not linking with the required library add -ldi to the LIBS line, before -logc, like this

Code: Select all

LIBS   :=    -lwiiuse -lbte -lfat -ldi -logc -lm

Thanks WinterMute.

You also should call DI_Init() as the first thing in your main.

How does that help?
