Why if I use the function

void setpalette(int color,int r,int g,int b)
{
  outportb(0x3c8,color);
  outportb(0x3c9,r);
  outportb(0x3c9,g);
  outportb(0x3c9,b);
}

in the main source file of a program set the palette correctly but if I
insert it in another file (in ex. palette.c) and i compile all with gcc -o
file.exe main.c palette.o (or palette.c) i see black screen?
I've tried to make a lib and use gcc -o file.exe main.c -libpal but... black
screen!
The application isn't crashed. I'm using VBE 2.0 and i've checked VGA
compatibility!!
Thanks.
