I can figure out how to enable GRRLIB. I have put the include files in a GRRLIB file in the include file in devkitpro.
D:\devkitPro\libogc\include\GRRLIB

I put the library files in the root of the lib folder
D:\devkitPro\libogc\lib

I copyed the additonal code from the GRRLIB Template file, but my problem is in the makefile.
it says

GRRLIB.c
linking ... pong.elf
d:/devkitpro/devkitppc/bin/../lib/gcc/powerpc-gekko/4.2.4/../../../../powerpc-gekko/bin/ld.exe: cannot find -lpng
collect2: ld returned 1 exit status
make[1]: *** [/d/homebrew/mystuff/pong/pong.elf] Error 1
"make": *** [build] Error 2

I havent added any pictures to my project yet, i dont know what i'm doing wrong
thanks

What I had to do was put the GRRLIB include folder and the libpng include folder inside my project's SOURCE folder, then in my Makefile, my SOURCES line looks like this:

SOURCES:= source source/gfx source/GRRLIB source/GRRLIB/fonts source/libpng source/libpng/pngu

I'm probably making some stupid mistake, but it isn't working. i don't think the problem is in the makefile because it isn't even linking it yet.
the error i'm getting is

I'm assuming from this you're trying to load a jpg file? I don't use jpegs in my project at all, all of my graphics are .PNG which are converted to .h files using WiiBuilder 1.0. I think last time I tried to use the jpeglib, it didn't work for me either.

Hmm....maybe post your Makefile, cus it sounds like it's trying to pull from the GRRLIB files in your project source, as well as from another source, and they're conflicting.

EDIT: The more I think about this, the more I want to think you just copy/pasted the SOURCES line I posted. If that's what you did, try removing the following part sof the SOURCES line, then recompile:

source/GRRLIB source/GRRLIB/fonts

Add this to your makefile (just before or just after the .jpg rule) if you are trying to use .png buffers:

#---------------------------------------------------------------------------------
# This rule links in binary data with the .png extension
#---------------------------------------------------------------------------------
%.png.o	:	%.png
#---------------------------------------------------------------------------------
	@echo $(notdir $<)
	$(bin2o)

-include $(DEPENDS)

This will use bin2o to turn your .png images in your projects data folder into buffers.

I hope that helps,

Edited 1 time(s). Last edit at 03/18/2009 12:25AM by Arikado.

thanks, but what should i change it to? i found the code that uses these and i just use the templete from the codemii tutorial

Here is where i found all of the rmode and xbf

	VIDEO_Init();
	WPAD_Init();
	GRRLIB_Init();

	rmode = VIDEO_GetPreferredMode(NULL);

	xfb = MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
	console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);

	VIDEO_Configure(rmode);
	VIDEO_SetNextFramebuffer(xfb);
	VIDEO_SetBlack(FALSE);
	VIDEO_Flush();
	VIDEO_WaitVSync();
	if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();
	WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
	WPAD_SetVRes(0, 640, 480);
}

Trying changing this:

	VIDEO_Init();
	WPAD_Init();
	GRRLIB_Init();

	rmode = VIDEO_GetPreferredMode(NULL);

	xfb = MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
	console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);

	VIDEO_Configure(rmode);
	VIDEO_SetNextFramebuffer(xfb);
	VIDEO_SetBlack(FALSE);
	VIDEO_Flush();
	VIDEO_WaitVSync();
	if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();
	WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
	WPAD_SetVRes(0, 640, 480);
}

To this:

	GRRLIB_InitVideo();
	WPAD_Init();

	console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);

	WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
	WPAD_SetVRes(0, 640, 480);
}

I wonder if somebody made a template with the location of each file, and the makefile and basic main.c needed for grrlib, it might help all of us.

Make sure you're not including any headers more than once.

Ok i lost most of the errors, i put grrlib.h and grrlib.c in my header, so i got rid of grrlib.c and got this error

main.c

It's because of this line in your Makefile:

LIBDIRS	:= $(CURDIR)

Make a folder in the directory with your Makefile, called lib, and copy the libpng.a file into it, then recompile, see if that helps.

The first error is one you made and must fix in line 14 of your code. I assume you have an if statement there?

No, i don't
this is the code that is there

14 extern "C" {
15	 #include "GRRLIB/GRRLIB.h"
16 }

Also, as i look over my code the header file GRRLIB/GRRLIB.h is already there

Hey,

you don't need the extern "C" {} as you are including GRRLIB to a C-file. You'll only want to do that if you include it to a C++ file.

There is no library version of GRRLIB (if you don't create it yourself). Thus you need to put GRRLIB.h and GRRLIB.c in your project directory. For the libraries that come with GRRLIB (libjpeg, libpng), create a directory "lib" in the root of your project directory as suggested earlier. Put the libraries (.a) in that directory. The header files go in to your source folder.
You may need to change some #include statements, depending on where you put the files in your source folder.

Last step is to tell the linker where to find the libraries and which libraries to link.
Add

LIBDIRS	:= $(CURDIR)

to the Makefile to add the lib folder of your project to the directories the linker is searching for libraries. Finally tell the linker which libraries to link by adding -lpng -ljpeg to that line of your Makefile:

LIBS	:=	-lz -lwiiuse -lbte -logc -lm
