From b1ecd10fe83594394ba11babc8ca9ccee8906e73 Mon Sep 17 00:00:00 2001 From: tobigun Date: Thu, 1 May 2008 00:39:04 +0000 Subject: Applied this fix https://sourceforge.net/tracker/index.php?func=detail&aid=1902924&group_id=43805&atid=437446 for 64bit compatibility with SDL. Thanks kambi for the patch, and escaped, tronikku and all the others for some other patches and/or testing. Now USDX should be x64 compatible. Please test and report errors. git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@1049 b956fd51-792f-4845-bead-9b4dfca2ff2c --- Game/Code/lib/JEDI-SDL/SDL/Pas/sdl.pas | 8648 +++++++++++++------------- Game/Code/lib/JEDI-SDL/SDL/Pas/sdlutils.pas | 8722 +++++++++++++-------------- Game/Code/lib/JEDI-SDL/jedi-sdl-64bit.patch | 1280 ++++ 3 files changed, 9968 insertions(+), 8682 deletions(-) create mode 100644 Game/Code/lib/JEDI-SDL/jedi-sdl-64bit.patch (limited to 'Game') diff --git a/Game/Code/lib/JEDI-SDL/SDL/Pas/sdl.pas b/Game/Code/lib/JEDI-SDL/SDL/Pas/sdl.pas index 29bc7123..2eede417 100644 --- a/Game/Code/lib/JEDI-SDL/SDL/Pas/sdl.pas +++ b/Game/Code/lib/JEDI-SDL/SDL/Pas/sdl.pas @@ -1,4321 +1,4327 @@ -unit sdl; -{ - $Id: sdl.pas,v 1.38 2008/01/26 10:09:32 savage Exp $ - -} -{******************************************************************************} -{ } -{ JEDI-SDL : Pascal units for SDL - Simple DirectMedia Layer } -{ Conversion of the Simple DirectMedia Layer Headers } -{ } -{ Portions created by Sam Lantinga are } -{ Copyright (C) 1997-2004 Sam Lantinga } -{ 5635-34 Springhouse Dr. } -{ Pleasanton, CA 94588 (USA) } -{ } -{ All Rights Reserved. } -{ } -{ The original files are : SDL.h } -{ SDL_main.h } -{ SDL_types.h } -{ SDL_rwops.h } -{ SDL_timer.h } -{ SDL_audio.h } -{ SDL_cdrom.h } -{ SDL_joystick.h } -{ SDL_mouse.h } -{ SDL_keyboard.h } -{ SDL_events.h } -{ SDL_video.h } -{ SDL_byteorder.h } -{ SDL_version.h } -{ SDL_active.h } -{ SDL_thread.h } -{ SDL_mutex .h } -{ SDL_getenv.h } -{ SDL_loadso.h } -{ } -{ The initial developer of this Pascal code was : } -{ Dominique Louis } -{ } -{ Portions created by Dominique Louis are } -{ Copyright (C) 2000 - 2004 Dominique Louis. } -{ } -{ } -{ Contributor(s) } -{ -------------- } -{ Tom Jones His Project inspired this conversion } -{ Matthias Thoma } -{ } -{ Obtained through: } -{ Joint Endeavour of Delphi Innovators ( Project JEDI ) } -{ } -{ You may retrieve the latest version of this file at the Project } -{ JEDI home page, located at http://delphi-jedi.org } -{ } -{ The contents of this file are used with permission, subject to } -{ the Mozilla Public License Version 1.1 (the "License"); you may } -{ not use this file except in compliance with the License.
