刘皓 42c4ff9497 Make `sandbox_malloc` into a coroutine According to AddressSanitizer, when `sandbox_malloc` causes the WebAssembly memory to grow in size, every single coroutine on the sandbox stack gets corrupted. So if `sandbox_malloc` is going to cause the memory to grow in size, we need to yield so that there are no coroutines on the sandbox stack while the reallocation occurs.		2025-02-17 00:38:40 -05:00

README.md

The build process for the libretro core is divided into two stages.

Stage 1

All the files produced by this stage are platform-agnostic, so you can run this build stage on any computer, regardless of which operating system or CPU architecture the libretro core is for.

Required software:

C and C++ compilers
Make
GNU Autotools
Git
xxd
curl
Info-ZIP Zip (the zip package found in many package managers)
WASI SDK (currently you need WASI SDK version 21; later versions don't work yet)
Binaryen
WABT
Either Universal Ctags or Exuberant Ctags

Go to the directory that this README.md is in and run this command, filling in the paths to WASI SDK, wasm-opt from Binaryen, wasm2c from WABT and ctags from Universal Ctags or Exuberant Ctags accordingly:

make WASI_SDK=/path/to/wasi-sdk WASM_OPT=/path/to/binaryen/bin/wasm-opt WASM2C=/path/to/wabt/bin/wasm2c CTAGS=/path/to/ctags

This will produce the directory "libretro/build/libretro-stage1".

Stage 2

This stage produces the actual core file.

Required software:

C and C++ compilers
Git
Meson
Ninja
CMake

No software libraries are required other than the system libraries.

Go to the root directory of this repository and run:

meson setup build -Dlibretro=true
cd build
ninja
