For best compatibility you +should compile your application the same way. + +Please note that building SDL requires at least Xcode 4.6 and the 10.7 SDK +(even if you target back to 10.5 systems). PowerPC support for Mac OS X has +been officially dropped as of SDL 2.0.2. + +To use the library once it's built, you essential have two possibilities: +use the traditional autoconf/automake/make method, or use Xcode. + +============================================================================== +Caveats for using SDL with Mac OS X +============================================================================== + +Some things you have to be aware of when using SDL on Mac OS X: + +- If you register your own NSApplicationDelegate (using [NSApp setDelegate:]), + SDL will not register its own. This means that SDL will not terminate using + SDL_Quit if it receives a termination request, it will terminate like a + normal app, and it will not send a SDL_DROPFILE when you request to open a + file with the app. To solve these issues, put the following code in your + NSApplicationDelegate implementation: + + + - (NSApplicationTerminateReply)applicationShouldTerminate:(NSApplication *)sender + { + if (SDL_GetEventState(SDL_QUIT) == SDL_ENABLE) { + SDL_Event event; + event.type = SDL_QUIT; + SDL_PushEvent(&event); + } + + return NSTerminateCancel; + } + + - (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filename + { + if (SDL_GetEventState(SDL_DROPFILE) == SDL_ENABLE) { + SDL_Event event; + event.type = SDL_DROPFILE; + event.drop.file = SDL_strdup([filename UTF8String]); + return (SDL_PushEvent(&event) > 0); + } + + return NO; + } + +============================================================================== +Using the Simple DirectMedia Layer with a traditional Makefile +============================================================================== + +An existing autoconf/automake build system for your SDL app has good chances +to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary +that you can distribute to users, you need to put the generated binary into a +so called "bundle", which basically is a fancy folder with a name like +"MyCoolGame.app". + +To get this build automatically, add something like the following rule to +your Makefile.am: + +bundle_contents = APP_NAME.app/Contents +APP_NAME_bundle: EXE_NAME + mkdir -p $(bundle_contents)/MacOS + mkdir -p $(bundle_contents)/Resources + echo "APPL????" > $(bundle_contents)/PkgInfo + $(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/ + +You should replace EXE_NAME with the name of the executable. APP_NAME is what +will be visible to the user in the Finder. Usually it will be the same +as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME +usually is "TestGame". You might also want to use @PACKAGE@ to use the package +name as specified in your configure.in file. + +If your project builds more than one application, you will have to do a bit +more. For each of your target applications, you need a separate rule. + +If you want the created bundles to be installed, you may want to add this +rule to your Makefile.am: + +install-exec-hook: APP_NAME_bundle + rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app + mkdir -p $(DESTDIR)$(prefix)/Applications/ + cp -r $< /$(DESTDIR)$(prefix)Applications/ + +This rule takes the Bundle created by the rule from step 3 and installs them +into $(DESTDIR)$(prefix)/Applications/. + +Again, if you want to install multiple applications, you will have to augment +the make rule accordingly. + + +But beware! That is only part of the story! With the above, you end up with +a bare bone .app bundle, which is double clickable from the Finder. But +there are some more things you should do before shipping your product... + +1) The bundle right now probably is dynamically linked against SDL. That + means that when you copy it to another computer, *it will not run*, + unless you also install SDL on that other computer. A good solution + for this dilemma is to static link against SDL. On OS X, you can + achieve that by linking against the libraries listed by + sdl-config --static-libs + instead of those listed by + sdl-config --libs + Depending on how exactly SDL is integrated into your build systems, the + way to achieve that varies, so I won't describe it here in detail +2) Add an 'Info.plist' to your application. That is a special XML file which + contains some meta-information about your application (like some copyright + information, the version of your app, the name of an optional icon file, + and other things). Part of that information is displayed by the Finder + when you click on the .app, or if you look at the "Get Info" window. + More information about Info.plist files can be found on Apple's homepage. + + +As a final remark, let me add that I use some of the techniques (and some +variations of them) in Exult and ScummVM; both are available in source on +the net, so feel free to take a peek at them for inspiration! + + +============================================================================== +Using the Simple DirectMedia Layer with Xcode +============================================================================== + +These instructions are for using Apple's Xcode IDE to build SDL applications. + +- First steps + +The first thing to do is to unpack the Xcode.tar.gz archive in the +top level SDL directory (where the Xcode.tar.gz archive resides). +Because Stuffit Expander will unpack the archive into a subdirectory, +you should unpack the archive manually from the command line: + cd [path_to_SDL_source] + tar zxf Xcode.tar.gz +This will create a new folder called Xcode, which you can browse +normally from the Finder. + +- Building the Framework + +The SDL Library is packaged as a framework bundle, an organized +relocatable folder hierarchy of executable code, interface headers, +and additional resources. For practical purposes, you can think of a +framework as a more user and system-friendly shared library, whose library +file behaves more or less like a standard UNIX shared library. + +To build the framework, simply open the framework project and build it. +By default, the framework bundle "SDL.framework" is installed in +/Library/Frameworks. Therefore, the testers and project stationary expect +it to be located there. However, it will function the same in any of the +following locations: + + ~/Library/Frameworks + /Local/Library/Frameworks + /System/Library/Frameworks + +- Build Options + There are two "Build Styles" (See the "Targets" tab) for SDL. + "Deployment" should be used if you aren't tweaking the SDL library. + "Development" should be used to debug SDL apps or the library itself. + +- Building the Testers + Open the SDLTest project and build away! + +- Using the Project Stationary + Copy the stationary to the indicated folders to access it from + the "New Project" and "Add target" menus. What could be easier? + +- Setting up a new project by hand + Some of you won't want to use the Stationary so I'll give some tips: + * Create a new "Cocoa Application" + * Add src/main/macosx/SDLMain.m , .h and .nib to your project + * Remove "main.c" from your project + * Remove "MainMenu.nib" from your project + * Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path + * Add "$(HOME)/Library/Frameworks" to the frameworks search path + * Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS" + * Set the "Main Nib File" under "Application Settings" to "SDLMain.nib" + * Add your files + * Clean and build + +- Building from command line + Use pbxbuild in the same directory as your .pbproj file + +- Running your app + You can send command line args to your app by either invoking it from + the command line (in *.app/Contents/MacOS) or by entering them in the + "Executables" panel of the target settings. + +- Implementation Notes + Some things that may be of interest about how it all works... + * Working directory + As defined in the SDL_main.m file, the working directory of your SDL app + is by default set to its parent. You may wish to change this to better + suit your needs. + * You have a Cocoa App! + Your SDL app is essentially a Cocoa application. When your app + starts up and the libraries finish loading, a Cocoa procedure is called, + which sets up the working directory and calls your main() method. + You are free to modify your Cocoa app with generally no consequence + to SDL. You cannot, however, easily change the SDL window itself. + Functionality may be added in the future to help this. + + +Known bugs are listed in the file "BUGS" |
