GP2X Compileing Error Sdl

[invinciblegod]

When I try to compile the simple hello world program using the gp2xdevkit, it gets a file format not recognized build error error 1. It compiles fine for windows. Am i supposed to change some formatting or what? I dont get it.



//The headers
#include "SDL/SDL.h"
#include <string>
//The attributes of the screen
const int SCREEN_WIDTH = 320;
const int SCREEN_HEIGHT = 240;
const int SCREEN_BPP = 24;
//The surfaces that will be used
SDL_Surface *message = NULL;
SDL_Surface *background = NULL;
SDL_Surface *screen = NULL;
SDL_Surface *load_image( std::string filename )
{
//Temporary storage for the image that's loaded
SDL_Surface* loadedImage = NULL;

//The optimized image that will be used
SDL_Surface* optimizedImage = NULL;
//Load the image
loadedImage = SDL_LoadBMP( filename.c_str() );
//If nothing went wrong in loading the image
if( loadedImage != NULL )
{
//Create an optimized image
optimizedImage = SDL_DisplayFormat( loadedImage );

//Free the old image
SDL_FreeSurface( loadedImage );
}
//Return the optimized image
return optimizedImage;
}
void apply_surface( int x, int y, SDL_Surface* source, SDL_Surface* destination )
{
//Make a temporary rectangle to hold the offsets
SDL_Rect offset;

//Give the offsets to the rectangle
offset.x = x;
offset.y = y;
//Blit the surface
SDL_BlitSurface( source, NULL, destination, &offset );
}
int main( int argc, char* args[] )
{
if( SDL_Init( SDL_INIT_EVERYTHING ) == -1 )
{
return 1;
}
//Set up the screen
screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE );
//If there was in error in setting up the screen
if( screen == NULL )
{
return 1;
}
//Set the window caption
SDL_WM_SetCaption( "Hello World", NULL );
message = load_image( "hello_world.bmp" );
background = load_image( "background.bmp" );
//Apply the background to the screen
apply_surface( 0, 0, background, screen );
//Apply the message to the screen
apply_surface( 90, 70, message, screen );
//Update the screen
if( SDL_Flip( screen ) == -1 )
{
return 1;
}
//Wait 2 seconds
SDL_Delay( 2000 );
//Free the surfaces
SDL_FreeSurface( message );
SDL_FreeSurface( background );

//Quit SDL
SDL_Quit();
}

what's the command you're using to compile and what is the exact error? did you clean the .o file(s) or are you trying to link windows' object code to arm libraries?

P.

i also saw this when trying to use Dev-C++ (as i see you are from a previous post)

for the sake of laziness i thought i'd try CodeBlocks and i've got to say it worked first time and is a nice IDE

here's the WIKI link :

did you clean the .o file(s) or are you trying to link windows' object code to arm libraries?

That sounds like the problem to me. Either use a different directory for your GP2X build, and/or do a "make clean" beforehand.

 

[invinciblegod]

now it says cannot find lmingw32. where is it supposed to be?

 

[yaustar]

Are you using the GP2X SDL libraries?

 

[invinciblegod]

yes. i am.

When not compiling for win32, you need to remove -lmingw32 from your linker options perhaps?
