GP32 The Devkitarm Blues.....

[Scott]

ok, this is starting to get me annoyed.

I can build something as complex as wonderboi, but I cant build something like this:

#include <gpstdlib.h>
#include <gpstdio.h>
#include <gpgraphic.h>
#include <gpmain.h>
#include <gpfont.h>


void GpMain(void *arg)
{


}

Or I get this:

and it happens even when I put the right stuff in the main funtion.

Heres my makefile contents:

Everything looks right to me.

Someone please help!

And if you could, could you just make some hello world code example for devkitarm? All i can find is stuff for Mr. mirko's stuff. Thanks!

 

[Oankali]

#include <gpstdlib.h>
.CFILES = gpmain.c

Try adding gpstart.c that is located in your GP SDK to .CFILES like:

.CFILES = $(GPSDK)/gpstart.c gpmain.c

 

[Scott]

oh yea, forgot about that devil...


Thanks
