GRRLIB Help

ok, but i get an error telling me it can't find the library include files

/GRRLIB.c:15:40: error: ../../lib/libpng/pngu/pngu.h: No such file or directory
d:/homebrew/mystuff/pong/source/GRRLIB.c:16:39: error: ../../lib/libjpeg/jpeglib.h: No such file or directory

how do i locate the file where makefile is in?, main.c is in source the next level up.

Your Makefile should be in the level UP from where your main.c is.

In other words, dont put main.c in the same folder as your makefile. Put main.c in the folder one level below it.

EX:
/projects/myawesomeapp/makefile
/projects/myawesomeapp/source/main.c

i know that, but how do i call the dir, call might be the wrong word, but how do i get there, i wont be able test anything cause my parents took my computer away

Oh snap, that sucks. Anyway, what do you mean by "call the dir"? And which dir in particular are you trying to "call"?

call was the wrong word, i was using the internet channel on my wii and i didn't want to type much

When a say #include "GRRLIB.h" that means it's in the directory that main.c is in right?
so if thats true and i want to access a file pngu.h that is in the lib directory where my makefile is in, how do i tell it to go up one directory and then locate pngu.h? the #include for pngu.h is in GRRLIB.h

i'll have to know this whether i move GRRLIB or not.

You'll have to change your makefile, I dont think it can be done in C.

Here's how my directory structure looks:

- Makefile
- lib (dir)
	- libpng.a
- source (dir)
	- gfx (dir)
		- image.h
	- GRRLIB (dir)
		- GRRLIB.c
		- GRRLIB.h
	- libpng (dir)
		- pngu (dir)
			- pngu.c
			- pngu.h
		- png.h
		- pngconf.h
	- main.cpp

Then, in your Makefile, your sources line would look like this:

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

If you need to include a file like pngu.h, you could add the following to the file you want to include it to:

#include "libpng/pngu/pngu.h"

That should point to what you need. Hope this helps.

when i originally looded at the #include i it had a /./ , or /../ , i can't remember is that how you do it, i don
t want to mess with my files that much, but i will if i hav to.

That was most likely the problem. I don't think it'll work if you use /./ or /../. Of course, I've never tried it that way, so it might.

so i'l have to change my files around?

Erm, yeah that would be the easy way.

Ok thanks it finally compiled, the problem was that it was trying to find the file's under GRRLIB so it couldn't find them, i havent done anything with GRRLIB, except initialize it so lets hope i can print a picture. thanks again

EDIT: I added this code and it came up with a bunch of errors
the code i'v added

extern const unsigned char ready[];
extern const int ready_size;

The errors i got

main.c

d:/homebrew/mystuff/pong/source/main.c:107: undefined reference to `ready'

I used raw2c to make a header file, i included the header file too.
i made the header file from a jpg image
is there a better way to load pictures with GRRLIB?

if i don't add the code then it says ready isn't referenced.

Instead of using JPEG, use PNG images, convert to .h with WiiBuilder 1.0, then use the following code to load the image:

#include "gfx/image.h"

u8 *tex_image=GRRLIB_LoadTexture(image);

GRRLIB_DrawImg(x,y,height,width,tex_image,0,1,1,255);

When you're converting the PNG with WiiBuilder, if you happen to get a warning that says "not a multiple of 4", just check the image dimensions and make sure whatever the dimensions are, they can divide by 4.

sorry, i was working with a png, and when i tryed that i got this

main.c
d:/homebrew/mystuff/pong/source/main.c: In function 'main':
d:/homebrew/mystuff/pong/source/main.c:106: error: 'ready' undeclared (first use in this function)

d:/homebrew/mystuff/pong/source/main.c:108: error: too many arguments to function 'GRRLIB_DrawImg'
make[1]: *** [main.o] Error 1
"make": *** [build] Error 2

I also deleted this part

extern const unsigned char ready[];
extern const int ready_size;

EDIT:
i just tryed it with this in

extern const unsigned char ready[];
extern const int ready_size;

And now i'm only getting

main.c
d:/homebrew/mystuff/pong/source/main.c: In function 'main':
d:/homebrew/mystuff/pong/source/main.c:109: error: incompatible types in initialization
d:/homebrew/mystuff/pong/source/main.c:111: error: incompatible type for argument 3 of 'GRRLIB_DrawImg'

d:/homebrew/mystuff/pong/source/main.c:111: error: too many arguments to function 'GRRLIB_DrawImg'
make[1]: *** [main.o] Error 1
"make": *** [build] Error 2

looks as though i'm using the wrong data type in the line you gave me here

u8 *tex_image=GRRLIB_LoadTexture(image);

GRRLIB_DrawImg(x,y,height,width,tex_image,0,1,1,255);

Ok, on this line:

GRRLIB_DrawImg(x,y,height,width,tex_image,0,1,1,255);

You should be putting the actual x,y,height,width values in. Example, instead of the above, it should be something like:

GRRLIB_DrawImg(0,0,640,480,tex_image,0,1,1,255);

And the "image.h" should be whatever the name of the image is you're including...I was just using "image" as an example name.

sorry, i forgot to say that i did all off that, and those are the errors i got, sorry for being unclear

Oh....I bet you're using the newest version of GRRLIB, which doesn't use GRRLIB_DrawImg. I'm using version 3.0. Sorry bout that....can't believe I didn't think about that earlier.

Ok, if anybody knows about the newer version of GRRLIB then can u help, i fixed my code, but it looks like something is still wrong
This is where the error is

	u8 *tex_ready=GRRLIB_LoadTexture(ready);

error:

d:/homebrew/mystuff/pong/source/main.c:134: error: incompatible types in initialization

Again, that's the different in syntax between version 3.0 and 4.0, I believe.
