================================================================================
Simple DirectMedia Layer for Native Client
================================================================================
Requirements:
* Native Client SDK (https://developer.chrome.com/native-client),
(tested with Pepper version 33 or higher).
The SDL backend for Chrome's Native Client has been tested only with the PNaCl
toolchain, which generates binaries designed to run on ARM and x86_32/64
platforms. This does not mean it won't work with the other toolchains!
================================================================================
Building SDL for NaCl
================================================================================
Set up the right environment variables (see naclbuild.sh), then configure SDL with:
configure --host=pnacl --prefix some/install/destination
Then "make".
As an example of how to create a deployable app a Makefile project is provided
in test/nacl/Makefile, which includes some monkey patching of the common.mk file
provided by NaCl, without which linking properly to SDL won't work (the search
path can't be modified externally, so the linker won't find SDL's binaries unless
you dump them into the SDK path, which is inconvenient).
Also provided in test/nacl is the required support file, such as index.html,
manifest.json, etc.
================================================================================
Running tests
================================================================================
Due to the nature of NaCl programs, building and running SDL tests is not as
straightforward as one would hope. The script naclbuild.sh in build-scripts
automates the process and should serve as a guide for users of SDL trying to build
their own applications.
Basic usage:
./naclbuild.sh path/to/pepper/toolchain (i.e. ~/naclsdk/pepper_35)
This will build testgles2.c by default.
If you want to build a different test, for example testrendercopyex.c:
SOURCES=~/sdl/SDL/test/testrendercopyex.c ./naclbuild.sh ~/naclsdk/pepper_35
Once the build finishes, you have to serve the contents with a web server (the
script will give you instructions on how to do that with Python).
================================================================================
TODO - Known Issues
================================================================================
* Audio backend is not usable yet.
* Testing of all systems with a real application (something other than SDL's tests)

* Added an event SDL_RENDER_DEVICE_RESET that is sent from the D3D renderers
when the D3D device is lost, and from Android's event loop when the GLES
