mkxp-z/libretro/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
• GNU Make
• GNU Autotools
• GNU Bison
• Git
• curl
• Info-ZIP's 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
