NAME
embuilder - Tool to manage building of Emscripten system libraries and ports
DESCRIPTION
usage: embuilder.py [-h] [--lto] [--lto=thin] [--pic] [--force] [--verbose]
[--wasm64]
{build,clear,rebuild} [targets ...]
Tool to manage building of system libraries and ports.
In general emcc will build them automatically on demand, so you do not strictly need to use this tool,
but it gives you more control over the process (in particular, if emcc does this automatically, and you
are running multiple build commands in parallel, confusion can occur).
positional arguments:
{build,clear,rebuild} targets see below
options:
-h, --help
show this help message and exit
--lto build bitcode object for LTO
--lto=thin
build bitcode object for ThinLTO
--pic build relocatable objects for suitable for dynamic linking
--force
force rebuild of target (by removing it first)
--verbose
show build commands
--wasm64
use wasm64 architecture
Available targets:
build / clear
