Description

Hi!

I just threw wabt at a WASM binary module compiled against WASI SDK for the first time. To my surprise, the latest official wabt 1.0.39 binaries error out saying "wasi support not compiled in":

# wget https://github.com/WebAssembly/wabt/releases/download/1.0.39/wabt-1.0.39-linux-x64.tar.gz
# tar xf wabt-1.0.39-linux-x64.tar.gz 
# wabt-1.0.39/bin/wasm-interp --wasi build/xmlwf/xmlwf 
wasi support not compiled in

(Same with the wabt 1.0.34 shipped in Ubuntu 24.04.)

Is that to be expected? Is this planned to change? Are there limitations that make it impossible to ship binaries with WASI support baked in?

Thanks and best, Sebastian

Research direction

Reproduce the reported command with the official 1.0.39 Linux archive and wasm-interp, then compare its behavior with the WASI SDK-built module and the Ubuntu 1.0.34 package. Done means establishing whether release binaries are expected to include WASI support and, if so, identifying the release build limitation; otherwise, document the constraint.
