feat: Add libs/bzip2 to WLR #95

Closed assambar closed 1 year ago

assambar commented 1 year ago

This only builds the library. The accompanying binaries used signals and file ownership, which are not available on WASI.

Here is a sample release - https://github.com/assambar/webassembly-language-runtimes/releases/tag/libs%2Fbzip2%2F1.0.8%2B20230424-ffa3f41

Also, managed to build python with this and test it 

wasmtime --mapdir /::$(pwd) bin/python.wasm
Python 3.11.3 (tags/v3.11.3:f3909b8, Apr 24 2023, 11:57:12) [Clang 15.0.7 ] on wasi
