wasm-sdk

A Nix-based SDK for C and C++ development targeting WebAssembly.

Goals

  • Lean toolchain leveraging as much as possible from upstream sources.
  • Basic levels of WASI (no threading, no exceptions).

Versions

  • LLVM: 17
  • wasi-libc: 21

Usage

The package contains all required dependencies in the following build subdirectories:

  • bin: compilers (clang, clang++) and linker (wasm-ld)
  • include: libc headers
  • include/c++/v1: libcxx headers
  • lib: all libc and libcxx static libraries
  • lib/wasi: compiler-rt builtins static library
