Primary build targets are "emscripten-node-dl" (NodeJS, dynamic linking),
|
|
|
|
"emscripten-browser", and "wasi".
|
|
|
|
|
|
|
|
Emscripten builds require a recent Emscripten SDK. The tools looks for an
|
|
|
|
activated EMSDK environment (". /path/to/emsdk_env.sh"). System packages
|
|
|
|
(Debian, Homebrew) are not supported.
|
|
|
|
|
|
|
|
WASI builds require WASI SDK and wasmtime. The tool looks for 'WASI_SDK_PATH'
|
|
|
|
and falls back to /opt/wasi-sdk.
|
2022-09-11 04:51:23 -03:00
|
|
|
|
|
|
|
The 'build' Python interpreter must be rebuilt every time Python's byte code
|
|
|
|
changes.
