Isn't there some emscripten forge thing where we can pull some dependencies in?

Isn't there some emscripten forge thing where we can pull some dependencies in?

Quite possibly, but I'm not too familiar with emscripten, so that is the reason I tried to build my own wasm zlib, and find it that way like I did locally. That doesn't seem to be working on the Github runner though.

[mcbarton]

@vgvassilev I'll try again later using an environment yaml file like in xeus-cpp. Maybe https://repo.mamba.pm/emscripten-forge might have everything we will need, since it has zlib , which is the current stumbling block.

Can’t we try to get the llvm binaries from there?

The only reason I didn't is I because of the patches on clang 16 and 17 that CppInterOp uses.. Is this not an issue? I can add this to the environment yml file if not, as this appears to be working now. I just need to understand why it can't find the wasm installed dependencies. I can hardcode in the paths for now until I understand why.

@vgvassilev Now that I have the configure and build stage for the wasm build passing, can you delete the llvm cache for this PR? I want to see if I can get the wasm and non wasm builds using the same llvm cache. There doesn't appear to be any reason they can't use the same one.

I will take a look into codebase changes after this, but I may put the codebase changes as a subsequent PR if that is ok.

The cache for this PR is deleted now.

@vgvassilev My cache was not deleted. I just went to rebuild the cache, and it restored a llvm build from cache.

Strange. Now I deleted everything.

@vgvassilev This PR is ready for review.

[vgvassilev]

Thank you! I am afraid I will need help to review this one. Maybe @anutosh491 can help?

[mcbarton]

@anutosh491 are you able to review this PR for me please?

[anutosh491]

Ahh sorry for the delay on this, going through it now.

@vgvassilev The jobs failing after the suggested change to emscripten 3.1.45 are due to a cache issue as far as I can tell. Can you clear the cache and manually reactivate the workflow? It should get all green checks after this.

@mcbarton, the cache is cleaned. Maybe you can restart?

[mcbarton]

@anutosh491 do you have anymore comments on the PR, or do you approve it?

[vgvassilev]

Thanks @anutosh491. Well done @mcbarton. Now we need to figure out how to plug this into the conda recipe here...
