GRRLIB Help

Here is the line in the GRRLIB.h, could you help me?

GRRLIB.h

GRRLIB_texImg GRRLIB_LoadTexture(const unsigned char my_img[]);

inline void GRRLIB_DrawImg(f32 xpos, f32 ypos, GRRLIB_texImg tex, float degrees, float scaleX, f32 scaleY, u32 color );

my code

u8 *tex_ready=GRRLIB_LoadTexture(ready);

	GRRLIB_DrawImg(0,0,tex_ready,0,1,1,0x00ff00ff);

I Want to show a pic the size of the entire screen

I think what's missing is your width and height variables. Try adding this to the inline void GRRLIB_DrawImg section of your GRRLIB.h file, after your xpos,ypos:

u16 width, u16 height

Then add your actual width and height variables to the GRRLIB_DrawImg part of your code.

ok, but my error is here

	u8 *tex_ready=GRRLIB_LoadTexture(ready);

once i get this i know that the next line will work. in my ready.h file

#ifndef _Ready_h_
#define _Ready_h_
//---------------------------------------------------------------------------------
const unsigned char Ready[] = {
 A bunch of hex values
};
const int Ready_size = 63773;
//---------------------------------------------------------------------------------
#endif //_Ready_h_

The compiler is case-sensitive, so since your "ready.h" file code says Ready, you'll have to the LoadTexture code to a capital "R" as well, otherwise, the compiler will say it is undeclared. Example:

#include "gfx/Ready.h"
u8 *tex_ready=GRRLIB_LoadTexture(Ready);

Case-sensitive is a pain sometimes, but it just means you have to pay closer attention to your code.

Thanks I will test when I get back to my computer
Ok i changed all to Ready, and nothing different. I checked my file and it is Ready. I belive the problem is in the

u8 *tex_Ready

or in

(Ready)

Should this really be this hard?

GRRLIB 4.0.0 is not using a pointer to a texture anymore, it's using a struct called GRRLIB_texImg.

GRRLIB_texImg GRRLIB_LoadTexture(const unsigned char my_img[]);

In the file you downloaded (http://grrlib.santo.fr/release/GRRLib4.0.0.rar) there is a folder called examples, go and the look at the code.

Thanks, i saw that moments before i check here. I fixed and now there is another problem

linking ... pong.elf
GRRLIB.o: In function `GRRLIB_LoadTexturePNG':

collect2: ld returned 1 exit status
make[1]: *** [/d/homebrew/mystuff/pong/pong.elf] Error 1

If you need any of my code just tell me which part and i will post it

Also, is it possible to make your own fonts for GRRLIB, and how?

Make sure this path is OK in GRRLIB.c:
#include "../libpng/pngu/pngu.h" // This is mine

Make sure the lib is included in your Make file:
LIBS := ......... -lpng ................

In the Make file the path needs to be OK too:
GRRLIB := ../../GRRLIB
TARGET := $(notdir $(CURDIR))
BUILD := build
SOURCES := source source/gfx $(GRRLIB)/GRRLIB $(GRRLIB)/lib/libpng/pngu
DATA := data
INCLUDES :=

i added the parts in my makefile and it compiled, no errors :) but nothing, other than normal, showed on my screen. i'v put the code that puts the picture onsceen in my loop and outside of it, what am i doing wrong

Try to use (paste) the code from an example, there is a folder called examples in the rar file.

I Finally got it to work and it only took 50 posts. I copyed some txt and it compiled correct and i got my image
Thanks to everyone that has helped.
Ok now i can't get GRRLIB_Printf to work, i copied the code from the demo for everything up to GRRLIB_Printf and this is what i put for Printf

GRRLIB_Printf(0,0,tex_font,0xffffff,0,"Hello World of GRRLIB");
