Hi!
Using Lasarus 1.4.4
I'm following the SDL tutorial at
http://www.freepascal-meets-sdl.net/
and get problems very fast.

looking at http://www.freepascal-meets-sdl.net/chapter-5-drawing-primitives/ I have the code starting like this

program Chapter5_SDL2;
uses SDL2;
var
i : integer;
sdlWindow1 : PSDL_Window;
sdlRenderer : PSDL_Renderer;
sdlRect1 : PSDL_Rect;
sdlPoints1 : array[0..499] of PSDL_Point;
begin
  //initilization of video subsystem
  if SDL_Init( SDL_INIT_VIDEO ) < 0 then HALT;
  sdlWindow1 := SDL_CreateWindow( 'Window1', 50, 50, 500, 500,
SDL_WINDOW_SHOWN );
  if sdlWindow1 = nil then HALT;
  writeln('1');
  sdlRenderer := SDL_CreateRenderer( sdlWindow1, -1, 0 );
  writeln('2');
  if sdlRenderer = nil then HALT;
and so on

However it crashes with runtime error 217 on line
sdlRenderer := SDL_CreateRenderer( sdlWindow1, -1, 0 ); I get '1' on the screen but not '2'

C:\bnl\svn\trunk\pascal\sdl-stuff>chapter5_sdl2.exe 1

if run from Lazarus, I get some assembler listing

.....

and I have no clue where i crashes, but I presume it is in sdl2.dll somewhere.
Downloaded the latest 64 bit for (2.0.4)
searching throught the disk gives exactly 1 sdl2.dll

C:\>dir /s sdl2.dll
Directory of C:\bnl\bin

Total Files Listed:
1 File(s) 1 230 336 bytes
0 Dir(s) 122 686 066 688 bytes free

Anyone has some ideas what to do.
Needless to say, google runtime error 217 gives no clear indication on why it is complaining.

I had Lazarus 1.6 before, but downgraded because of bug in databse interface reagrding floats.
(thread with subject "TPQConnection and float")

Nevermind, I got the 32 bit version to work for both db interface and sdl2.
