Hello!

I've been doing a bit of DS learning recently and I'm slightly confused on where to place my files and how to organize my makefile

Right now I have a directory named NDS, inside that is /build/, /source/, and /gfx/
Inside of /gfx/ I have a 16x32 256-color sprite bitmap which I can convert with:

Code:

C:/grit/grit obj/sprite.bmp -gB4 -gt -ftc -W3 -pe16 -gu8

(I also have sprite.grit inside /gfx/)

Code:

-gB4 -gt -ftc -W3 -pe16 -gu8

My makefile looks like this (I copy-pasted out of a tutorial on sprites and changed a few things):

Code:

.SUFFIXES:

ifeq ($(strip $(DEVKITARM)),)
$(error "Please set DEVKITARM in your environment. export DEVKITARM=<path to>devkitARM")
endif

include $(DEVKITARM)/ds_rules
TARGET    := $(shell basename $(CURDIR))
BUILD    := build
SOURCES    := source
DATA    := data
INCLUDES := include
GRAPHICS := gfx

ARCH := -mthumb -mthumb-interwork

CFLAGS := -g -Wall -O2\
         -march=armv5te -mtune=arm946e-s -fomit-frame-pointer\
      -ffast-math \
      $(ARCH)

CFLAGS += $(INCLUDE) -DARM9
CXXFLAGS := $(CFLAGS) -fno-rtti -fno-exceptions

ASFLAGS := -g $(ARCH)
LDFLAGS = -specs=ds_arm9.specs -g $(ARCH) -mno-fpu -Wl,-Map,$(notdir $*.map)

LIBS := -lnds9

LIBDIRS := $(LIBNDS)

ifneq ($(BUILD),$(notdir $(CURDIR)))

export OUTPUT := $(CURDIR)/$(TARGET)

export VPATH := $(foreach dir,$(SOURCES),$(CURDIR)/$(dir)) \
            $(foreach dir,$(GRAPHICS),$(CURDIR)/$(dir)) \
            $(foreach dir,$(DATA),$(CURDIR)/$(dir))

export DEPSDIR := $(CURDIR)/$(BUILD)

CFILES    := $(foreach dir,$(SOURCES),$(notdir $(wildcard $(dir)/*.c)))
CPPFILES := $(foreach dir,$(SOURCES),$(notdir $(wildcard $(dir)/*.cpp)))
SFILES    := $(foreach dir,$(SOURCES),$(notdir $(wildcard $(dir)/*.s)))
BINFILES := $(foreach dir,$(DATA),$(notdir $(wildcard $(dir)/*.*)))
PNGFILES := $(foreach dir,$(GRAPHICS),$(notdir $(wildcard $(dir)/*.png)))

ifeq ($(strip $(CPPFILES)),)
export LD := $(CC)
else
export LD := $(CXX)
endif

export OFILES := $(addsuffix .o,$(BINFILES)) \
            $(PNGFILES:.png=.o) \
            $(CPPFILES:.cpp=.o) $(CFILES:.c=.o) $(SFILES:.s=.o)

export INCLUDE := $(foreach dir,$(INCLUDES),-I$(CURDIR)/$(dir)) \
            $(foreach dir,$(LIBDIRS),-I$(dir)/include) \
            $(foreach dir,$(LIBDIRS),-I$(dir)/include) \
            -I$(CURDIR)/$(BUILD)

export LIBPATHS := $(foreach dir,$(LIBDIRS),-L$(dir)/lib)

.PHONY: $(BUILD) clean

$(BUILD):
@[ -d $@ ] || mkdir -p $@
@make --no-print-directory -C $(BUILD) -f $(CURDIR)/Makefile

clean:
@echo clean ...
@rm -fr $(BUILD) $(TARGET).elf $(TARGET).nds $(TARGET).arm9 $(TARGET).ds.gba

else

DEPENDS := $(OFILES:.o=.d)

$(OUTPUT).nds : $(OUTPUT).arm9
$(OUTPUT).arm9 : $(OUTPUT).elf
$(OUTPUT).elf : $(OFILES)

%.bin.o : %.bin
@echo $(notdir $<)
@$(bin2o)

%.c %.h : %.bmp %.grit
grit $< -ftc -o$*

-include $(DEPENDS)

endif

And then I have main.cpp (mainly copy-pasted as well with a tiny modification to see if the sprite.h is loading correctly):

Code:

#include <nds.h>
#include <stdio.h>

#include "sprite.h"
volatile int frame = 0;
//---------------------------------------------------------------------------------
void Vblank() {
frame++;
}

//---------------------------------------------------------------------------------
int main(void) {
touchPosition touchXY;

irqSet(IRQ_VBLANK, Vblank);

consoleDemoInit();

iprintf(" Hello DS dev'rs\n");
iprintf(" \x1b[32mwww.devkitpro.org\n");
iprintf(" \x1b[32;1mwww.drunkencoders.com\x1b[39m");

while(1) {

   swiWaitForVBlank();
   touchRead(&touchXY);

   // print at using ansi escape sequence \x1b[line;columnH
   iprintf("\x1b[10;0HFrame = %d",frame);
   iprintf("\x1b[16;0HTouch (x,y) = (%03d, %03d)",touchXY.px,touchXY.py);
   iprintf("\x1b[17;0HPal 1 [%4d]",spritePal[1]);

}

return 0;
}

And when running the GCC make...

Code:

main.cpp
arm-eabi-g++ -MMD -MP -MF /c/Users/John/NDS/build/main.d -g -Wall -O2 -march=armv5te -mtune=arm946e-s -fomit-frame-pointer -ffast-math -mthumb -mthumb-interwork -I/c/Users/John/NDS/include -I/c/devkit
Pro/libnds/include -I/c/devkitPro/libnds/include -I/c/Users/John/NDS/build -DARM9 -fno-rtti -fno-exceptions -c /c/Users/John/NDS/source/main.cpp -o main.o
c:/Users/John/NDS/source/main.cpp:4:22: error: rhahkzor.h: No such file or directory
c:/Users/John/NDS/source/main.cpp: In function 'int main()':
c:/Users/John/NDS/source/main.cpp:32: error: 'rhahkzorPal' was not declared in this scope
make[1]: *** [main.o] Error 1
make: *** [build] Error 2

Am I placing my graphics in the wrong folder or is my makefile wrong?
I would really, really appreciate any help that you could give me - I'm brand new to programming in C++ and pretty much everything up there^^^ :)

Nevermind, I solved it. silly me and just copy-pasting without reading every line - I never changed the PNGFILES to BMPFILES :) Sorry to bother!
