Setting up a development environment (Mac)

From wiki.gp2x.org

Currently, only one toolkit for the GP2x is available for Mac OSX, devkitGP2X (though Open2x may work either natively or through Fink, it is currently untested).

Download the pre-built devkitGP2X for Mac from the archive (direct link) and it should mount and install by itself.

The toolkit should now work.

To be safe, you should add '/opt/local/devkitpro/devkitGP2X/bin/' to your path.

Developing using SDL

If you want to develop using SDL, then you'll need to install the ARM SDL libraries too. They extract into /opt.

Here is a sample makefile that will build an SDL program called "helloworld.c" into "helloworld.gpe":

CROSS_COMPILE=/opt/local/devkitpro/devkitGP2X/bin/arm-linux-
SDL_BASE=/opt/local/gp2x/bin/arm-open2x-linux-
LDFLAGS=-static

CC=$(CROSS_COMPILE)gcc
CXX=$(CROSS_COMPILE)g++
STRIP=$(CROSS_COMPILE)strip

CFLAGS=`$(SDL_BASE)sdl-config --cflags` -O2 -Wall -Werror
CXXFLAGS=`$(SDL_BASE)sdl-config --cflags` -O2 -Wall -Werror
LIBS=`$(SDL_BASE)sdl-config --libs`

TARGET=helloworld.gpe
OBJS=helloworld.c

ALL_TARGETS=$(TARGET)

all: $(ALL_TARGETS)


$(TARGET): $(OBJS)
	$(CC) $(LDFLAGS) -o $(TARGET) $(OBJS) $(LIBS) $(CFLAGS)
	$(STRIP) $(TARGET)

clean:
	rm *.o $(TARGET)
