Hey @IsabelParedes @martinRenou

I'm kinda confused here. When I try to get this on macos, I see this

(xeus-cpp-wasm-build) anutosh491@Anutoshs-MacBook-Air build % micromamba install emscripten_emscripten-wasm32==3.1.45 -c https://repo.mamba.pm/emscripten-forge
https://repo.mamba.pm/emscripten-forge/osx-arm64    ??.?MB @  ??.?MB/s  1.5s
https://repo.mamba.pm/emscripten-forge/noarch        2.9kB @   1.3kB/s  2.1s

conda-forge/noarch                                  18.6MB @   2.1MB/s  8.9s

Does this mean our CI only works because we use ubuntu

xeus-r/.github/workflows/deploy-github-page.yml

Lines 23 to 25 in 933f00c

	- name: Github-page
	os: ubuntu-24.04
	emsdk_ver: "3.1.45"

I wanted to extrapolate this idea to xeus-cpp but then we already have emscripten based CI for macos :(
So my question here is if it even makes sense to have so much CI for the lite builds ?

If not why ? (asking cause its been there since quite some time and not sure I should get rid of all the osx ones ... rather the osx ones build much quicker than the ubuntu ones)

[martinRenou]

Yeah, I would probably not bother with so much CI for the emscripten build. Probably just the ubuntu host is enough?

It seems there is only a recipe for linux in https://beta.mamba.pm/channels/emscripten-forge/packages/emscripten_emscripten-wasm32. We could also probably update the recipe on emscripten-forge to provide emscripten_emscripten-wasm32 on more platforms.
