Hello!
I'm trying compile SDL "Hello, World"
---
import std.stdio;
import derelict.sdl2.sdl;
//Screen dimension constants
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;
int main()
{
DerelictSDL2.load();
//The window we'll be rendering to
SDL_Window* window = null;
//The surface contained by the window
SDL_Surface* screenSurface = null;
//Initialize SDL
if( SDL_Init( SDL_INIT_VIDEO ) < 0 )
{
printf( "SDL could not initialize! SDL_Error: %s\n",
SDL_GetError() );
}
else
{
//Create window
window = SDL_CreateWindow( "SDL Tutorial",
SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, SCREEN_WIDTH,
SCREEN_HEIGHT, SDL_WINDOW_SHOWN );
if( window == null )
{
printf( "Window could not be created! SDL_Error: %s\n",
SDL_GetError() );
}
else
{
//Get window surface
screenSurface = SDL_GetWindowSurface( window );
//Fill the surface white
SDL_FillRect( screenSurface, null, SDL_MapRGB(
screenSurface.format, 0xFF, 0x00, 0x00 ) );
//Update the surface
SDL_UpdateWindowSurface( window );
//Wait two seconds
SDL_Delay( 2000 );
}
}
//Destroy window
SDL_DestroyWindow( window );
//Quit SDL subsystems
SDL_Quit();
return 0;
}

$ dmd -I/path/to/DerelictSDL2/source
-I/path/to/derelict-util-2.0.6/source main.d
/path/to/DerelictSDL2/lib/libDerelictSDL2.a
/path/to/derelict-util-2.0.6/lib/libDerelictUtil.a -gc
It compiles but on running crashes (as shows valgrind) in
SDL_FillRect function.
BUT in gdb it runs successfully and I see red window.
What I'm doing wrong? How gdb can make not working code working?
dmd 2.071.1
Thank you!
