SDL on Delphi XE2

[kotai]

Hi again.

Now I can compile my projects in Win32 and Win64, but I like port to iOS and MacOSx.

Mac OSx
When I active Platform OSx I have this error in SDL.pas:

[DCC Fatal Error] sdl.pas(318): F1026 File not found: 'Windows.dcu'

317 {$IFDEF WINDOWS}
318   Windows;
319 {$ENDIF}

I'm compile for platform OSx but compiler think I'm compile to Windows.
How I can tell compiler that I am compiling for Mac OSx and not for Windows ?


iOS

When you select iOS and export to Xcode, game is compiled for Xcode in Mac by FPC 2.6.0 and I need SDL.pas in Mac.
When install in Mac "fpc-2.6.0.intel-macosx.pkg" from "FireMonkey-iOS.dmg" image, JEDI-SDL has installed in:

/Developer/Embarcadero/fpc/packages/sdl

but I do not know how add library path to use it when compile with Xcode.
Is there something like "Library" of Delphi where you can indicate paths for search *. pas ?

For test, I copy SDL.pas from "/Developer/Embarcadero/fpc/packages/sdl/src/SDL.pas" to my project folder but I have next error:

Target OS: Darwin/iPhoneSim fro i386
Compiling /Users/...../Naves.pas
Compiling /Users/...../sdl.pas
Fatal: Can't find unit x used by sdl
Fatal: Compilation aborted

I think problem is at line 311 of sdl.pas:

300{$IFDEF UNIX}
301  {$IFDEF FPC}
302  pthreads,
303  unixtype,
304  baseunix,
305  {$IFNDEF GP2X}    
306  unix,
307  {$ELSE}
308  unix;
309  {$ENDIF}
310  {$IFNDEF GP2X}
311  x,
312  xlib;
313  {$ENDIF}
314  {$ELSE}
315  Libc,
316  Xlib;
317  {$ENDIF}
318{$ENDIF}

Compiler think I'm compile for GP2x ?
How I can tell compiler that I am compiling for iOS and not for GP2X ?

Thanks.

The SDL headers are not really optimized for Delphi XE2 and I think for it to work on Mac OS X, you will to tweak a few compiler conditions in JEDI-SDL.inc. If I remember correctly, if compiled with Delphi on desktop machines, it assumes Windows is used as its platform.

With SDL 1.2 on iOS you have two problems:
- SDL 1.2 does not work on iOS, you need SDL 1.3/2.0 (try these headers: https://github.com/Stoney-FD/sdl13-pascal <-- They worked for me in the past (Disclaimer: I wrote them), but are pretty much alpha, if not pre-alpha)
- You can't link against dynamic libraries

Thanks for reply.

¿ SDL in iOS can't link against dynamic libraries ?
I download by mercurial SDL2.0 from http://hg.libsdl.org/SDL and I build in xcode file library "libSDL2.a"
¿ I can't work like windows and put in project folder the library "libSDL2.a" ?

If I can't complile for MacOS, no problem, but I like port my games to iOS.

Have you a small example in free pascal for test SDL in iOS ?

Thanks.
