An open source PlayStation 4 SDK.
Just run make on the PS4-SDK directory to build the library.
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
You must make sure that your compiler supports the System V AMD64 ABI calling convention. PS4-SDK relies on this for compatibility with Sony's functions and system calls.
At the moment, it is primarily focused on the kernel. For example, all semaphore system calls have been implemented, from 549 to 556.
However, using function pointers and the RESOLVE macro, we can call functions from other modules. For example, the socket functions from libSceNet.sprx.
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, or a mini Pong game could be developed.
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)
directories - List the contents of a directory
files - Read a file's size, and its contents
list_devices - List information about all USB devices connected
storage - Read raw image from a USB flash drive
