unexpected binaryen version

[Александр Гурьянов]

Hi. I use emsdk, and after updating to 3.1.20 I have following warnings:

emcc: warning: unexpected binaryen version: 109 (expected 104) [-Wversion-check]
emcc: warning: unexpected binaryen version: 109 (expected 104) [-Wversion-check]
em++: warning: unexpected binaryen version: 109 (expected 104) [-Wversion-check]

What does it mean? I used following commands

./emsdk install latest

./emsdk activate latest

source emsdk_env.sh

./emcc ...

I tried clear caches with --clear-cache, but warning still there...

the output of wasm-opt --version:

./upstream/bin/wasm-opt --version
wasm-opt version 109 (version_109-27-gb69d3a8fa)

This expected version looks wrong.  It should be expecting 109 if you are using 3.1.20.

Can you run `which emcc` and `emcc --version` to see why the wrong version seems to be being used?

cheers,

I also have following warnings:

Solved! The problem was in cmake files or project, seems that build script was generated when emscripten was located in emsdk/emscripten/main/. Seems newer emsdk uses emsdk/upstream/emscripten. After regenerating cmake build script everything is fine.
