I've got a problem when I try to compile my c code.

The first a follow the instruction on http://www.loirak.com/gameboy/gbprog.php and it worked.

So I try to write my own program using parts of other source code. My goal is just to display a picture. I ended up with that code :

-------------------------------------------------------------------------------------------------------------------------

#include <gb.h>

#include "nude_t.h"        /*the tiles and palette entries*/
#include "nude_t.c"
#include "nude_m.h"        /*the map (pointers to tiles)*/
#include "nude_m.c"
#include "nude_.h"        /*the map's palette entries (pointers to palette)*/
#include "nude_.c"


UWORD nudePalCGB[] =
{
  nudeTilesCGBPal0c0,nudeTilesCGBPal0c1,nudeTilesCGBPal0c2,nudeTilesCGBPal0c3,
  nudeTilesCGBPal1c0,nudeTilesCGBPal1c1,nudeTilesCGBPal1c2,nudeTilesCGBPal1c3,
  nudeTilesCGBPal2c0,nudeTilesCGBPal2c1,nudeTilesCGBPal2c2,nudeTilesCGBPal2c3,
  nudeTilesCGBPal3c0,nudeTilesCGBPal3c1,nudeTilesCGBPal3c2,nudeTilesCGBPal3c3,
  nudeTilesCGBPal4c0,nudeTilesCGBPal4c1,nudeTilesCGBPal4c2,nudeTilesCGBPal4c3,
  nudeTilesCGBPal5c0,nudeTilesCGBPal5c1,nudeTilesCGBPal5c2,nudeTilesCGBPal5c3,
  nudeTilesCGBPal6c0,nudeTilesCGBPal6c1,nudeTilesCGBPal6c2,nudeTilesCGBPal6c3,
  nudeTilesCGBPal7c0,nudeTilesCGBPal7c1,nudeTilesCGBPal7c2,nudeTilesCGBPal7c3
};

void main()
{

  set_bkg_palette( 7, 1, &nudePalCGB[28] );
  set_bkg_palette( 6, 1, &nudePalCGB[24] );
  set_bkg_palette( 5, 1, &nudePalCGB[20] );
  set_bkg_palette( 4, 1, &nudePalCGB[16] );
  set_bkg_palette( 3, 1, &nudePalCGB[12] );
  set_bkg_palette( 2, 1, &nudePalCGB[8] );
  set_bkg_palette( 1, 1, &nudePalCGB[4] );
  set_bkg_palette( 0, 1, &nudePalCGB[0] );

set_bkg_data(0, 161,nudeTiles);


  VBK_REG = 1;
  set_bkg_tiles(0,0,nudeMapWidth,nudeMapHeight,nudePal);

  VBK_REG = 0;
  set_bkg_tiles(0,0,nudeMapWidth,nudeMapHeight,nudeMap);


}

I use this make.bat :

C:\gbdk\bin\lcc -c -o main.o main.c

C:\gbdk\bin\lcc -Wl-yp0x143=0xC0 -Wl-yp0x14A=1 -o main.gb main.o

--------------------------------------------------------------------------------------------------------------------------

I don't know if the code really work but everytime I try to compile my code, I've got this message :

"main.c1: error: gb.h: undocumented I/O error"

I reinstall GBDK but the problem is still here...
