mkxp-z/retro

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

Phase 1

All the files produced by this phase are platform-agnostic, so you can run this build phase 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 "retro/build/retro-phase1".

Phase 2

This phase 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 -Dretro=true -Dretro_phase1_path=path/to/retro-phase1
cd build
ninja
