I'm having trouble compiling with the skeleton environment. I was able to successfully compile the Ndless demo, whereas Bwang's raycaster and a small test program I wrote won't compile. It seems to not be loading the headers properly.
Here is the code:

asm(".string \"PRG\"\n");
int main()
{
int antx = 160;
int anty = 120;
int dir = 1;
while (!isKeyPressed(KEY_NSPIRE_ESC)) {
if (getpixel(antx,anty) == 15) {
setpixel(anty,antx,0);
dir = dir - 1;
}
else {
setpixel(anty,antx,15);
dir = dir + 1;
}
if (dir == 0)
dir = 4;
else if (dir == 5)
dir = 1;
if (dir == 1)
antx = antx - 1;
else if (dir == 2)
anty = anty + 1;
else if (dir == 3)
antx = antx + 1;
else
anty = anty - 1;
if (antx == 0)
antx = 320;
else if (antx == 321)
antx = 1;
if (anty == 0)
anty = 240;
else if (anty == 241)
anty = 1;
}
return 0;
}

If it matters, I'm using the arm-elf-gcc version of yagarto.
