SDL Snake Mac OS
I'm trying to compile a cmake project on my mac, but it depends on the SDL framework. I installed this framework and after cmake then reported to me libSDL was not found I set following export vari.
- My operating system is macOS Mojave and I am experiencing the same thing. I've configured my development environment using Pyenv 1.2.9. On Pyenv, I've install Python 3.7.2 and Pygame 1.9.4. Python was installed using Pyenv and Pygame was installed using pip. When running my code snippet, I get this screen.
- The Haskell packages hsSDL2 and sdl2 are bindings to the C library libSDL. From Wikipedia: Simple DirectMedia Layer (SDL) is a cross-platform, free and open source software multimedia library written in C, that presents a simple interface to various platforms' graphics, sound, and input devices.
Is SDL software supported on a MAC OS?
0000027755/9/2018 9:16 PMUsing SDL applications on Apple Macintosh systems is not officially supported and we may not always be able to assist in configuring your Mac to make SDL software work. However, we will always try to help where we can and we will publish any relevant troubleshooting information in our knowledge base. SDL Trados software has not been developed to run on an Apple Macintosh environment and the software has never been tested on any Macintosh platform. SDL Trados Software is officially supported on a Microsoft Windows-based PC or an Intel-based Apple Mac computers running Windows as an operating system. |
For some specific errors we have seen on Mac environments, please take a look at this article: |
Here's the explanation.

Code Examples
Remarks
SDL_QUIT
SDL_QUIT events are generated for a variety of reasons. An application can choose to ignore the event, for example, if it wants to offer a prompt asking the user to save the current work.
An SDL_QUIT event is generated when the user clicks on the close button of the last existing window. This happens in addition to the SDL_WINDOWEVENT/SDL_WINDOWEVENT_CLOSE event, so the application can check whichever is appropriate, or both, or neither. If the application ignores this event and creates another window, SDL_QUIT will be sent again the next time the user clicks on the last remaining window's close button.
SDL_QUIT is not limited to window closing. On Mac OS X, pressing Command-Q (the standard keyboard shortcut for 'Quit this application') will cause SDL to generate an SDL_QUIT event, regardless of what windows exist at the time. The application is still responsible for terminating itself properly, however. Applications that completely ignore Command-Q will fail Mac App Store certification.
On POSIX systems, [SDL_Init]]() installs [signal handlers for SIGINT
(keyboard interrupt) and SIGTERM
(system termination request), if handlers do not already exist, that generate SDL_QUIT events as well. There is no way to determine the cause of an SDL_QUIT event, but setting a signal handler in your application will override the default generation of quit events for that signal.
Android, iOS and WinRT Events
Sdl Snake Mac Os X
What we currently label as 'Android, iOS and WinRT events' are specific to mobile and embedded devices that have different requirements than your usual desktop application. These events must be handled in an event filter, since often the OS needs an immediate response and will terminate your process shortly after sending the event, and if it sits in the SDL event queue, it'll be too late. You can handle everything else through a normal SDL_PollEvent() loop, but you should set up a callback with SDL_SetEventFilter() for these specific events.
This is how these events currently map to the underlying OS:
SDL event | What | iOS | Android | WinRT |
SDL_APP_TERMINATING | The application is being terminated by the OS. |
|
|
|
SDL_APP_LOWMEMORY | The application is low on memory, free memory if possible. |
|
| -- |
SDL_APP_WILLENTERBACKGROUND | The application is about to enter the background. |
|
|
|
SDL_APP_DIDENTERBACKGROUND | The application did enter the background and may not get CPU for some time. |
|
|
|
SDL_APP_WILLENTERFOREGROUND | The application is about to enter the foreground. |
|
|
|
SDL_APP_DIDENTERFOREGROUND | The application is now interactive. |
