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)
