Hello,
Sorry if I don't speak good english, I'm French ^^
When I want to try to compile the lesson 1 in the example of GRRLIB 4, I've got an error at the compilation
linking ... boot.elf main.o: In function `main': c:/devkitPro/examples/wii/boot/source/main.c:19: undefined reference to `GRRLIB_LoadTexture' c:/devkitPro/examples/wii/boot/source/main.c:22: undefined reference to `GRRLIB_Init' c:/devkitPro/examples/wii/boot/source/main.c:79: undefined reference to `GRRLIB_FillScreen' c:/devkitPro/examples/wii/boot/source/main.c:82: undefined reference to `GRRLIB_DrawImg' c:/devkitPro/examples/wii/boot/source/main.c:84: undefined reference to `GRRLIB_Render' c:/devkitPro/examples/wii/boot/source/main.c:97: undefined reference to `GRRLIB_FillScreen' c:/devkitPro/examples/wii/boot/source/main.c:100: undefined reference to `GRRLIB_DrawImg' c:/devkitPro/examples/wii/boot/source/main.c:101: undefined reference to `GRRLIB_Render' collect2: ld returned 1 exit status make[1]: *** [/c/devkitPro/examples/wii/boot/boot.elf] Error 1 "make": *** [build] Error 2 > Process Exit Code: 2 > Time Taken: 00:03
This is my code

}
GRRLIB_Exit();
free(tex_pirate.data);

}GRRLIB.h and pirate.h are in the same folder of the main.c

In your Makefile be sure to have a good path for GRRLIB:
#--------------------------------------------------------------------------------- # TARGET is the name of the output # BUILD is the directory where object files & intermediate files will be placed # SOURCES is a list of directories containing source code # INCLUDES is a list of directories containing extra header files #--------------------------------------------------------------------------------- GRRLIB := ../../GRRLIB TARGET := $(notdir $(CURDIR)) BUILD := build SOURCES := source source/gfx $(GRRLIB)/GRRLIB $(GRRLIB)/lib/libpng/pngu DATA := data INCLUDES :=

Thanks but now I've got this message
> "make" make[1]: *** No rule to make target `pngu.o', needed by `/c/devkitPro/examples/wii/boot/boot.elf'. Stop. "make": *** [build] Error 2
I don't know where can be the problem, why 'pngu.o' .

GRRLIB uses libpng and libjpeg so you need to add the libs and header files (.h) into your project
Your Makefile should look like this:
#--------------------------------------------------------------------------------- # any extra libraries we wish to link with the project #--------------------------------------------------------------------------------- LIBS := -lpng -ljpeg -lz -lfat -lwiiuse -lbte -logc -lm #--------------------------------------------------------------------------------- # list of directories containing libraries, this must be the top level containing # include and lib #--------------------------------------------------------------------------------- LIBDIRS := $(CURDIR)/$(GRRLIB)
Normally your supposed to keep the same file structure as the example and you change your Makefile like the message above and the include path in GRRLIB.c:
#include "../lib/libpng/pngu/pngu.h" #include "../lib/libjpeg/jpeglib.h" #include "GRRLIB.h"
