PS4 SDK
An open source PlayStation 4 SDK for writing userland applications which can be run with the PS4-playground.
Building and installing
You will need LLVM version 3.7 or later for compiling, and binutils for linking (from MinGW if you are on Windows).
Clone this repository locally, or download and extract a ZIP of the repository here.
Then create an environment variable called, PS4SDK which points to the base directory of the repository, using the Unix path style; for example:
/C/Users/Chris/Documents/GitHub/PS4-SDK
Build the libraries by running make on the libPS4 and libusbfatfs directories.
Finally, you can build examples by running make on them.
Design
At the moment, it is primarily focused on system calls.
However, using function pointers and the RESOLVE macro, we can call functions from other modules. For example, the socket functions from libSceNet.sprx.
Support
Whilst the SDK isn't capable of most basic functionality yet, such as displaying graphics, or receiving controller input, there are workarounds: rendering to an HTML5 canvas, and using third party USB controllers, or a DS/PSP wirelessly for example.
The SDK is currently in a state where projects like an FTP server, a mini Pong game, or GameBoy emulator could be developed.
Examples
hello - Load libc module and perform getpid system call
sockets - Send a message over a TCP socket
modules - Load and dump a module
threads - Create and wait for a thread to increment a variable
canvas - Render to an HTML5 canvas
camera - Initialise the PlayStation Camera and capture 10 frames
pad - Read controller input (not finished)
jit - Setting up JIT shared memory
Filesystem
directories - List the contents of a directory
files - Read a file's size, and its contents
USB
list_devices - List information about all USB devices connected
storage - Read raw image from a USB flash drive
usbfatfs - Read files from USB formatted with FAT
