Setup Local Build instructions fail for both micromamba & conda [apple silicon]

[tylere]

Working through the Setup Local Build docs, I am encountering issues creating the environment.

micromamba create

Using micromamba to create the environment

micromamba create -n emforge -f ci_env.yml

results in

(base) tylere@tylers-mbp recipes % micromamba create -n emforge -f ci_env.yml

conda create

Similarly, using conda to create the environment

conda env create -n emforge --file ci_env.yml

results in

(base) tylere@tylers-mbp recipes % conda env create -n emforge --file ci_env.yml
Collecting package metadata (repodata.json): done

@tylere this is only intended to work for linux64 atm.

[DerThorsten]

playwright / patchelf are not strictly needed for building packages.

Playwright is only for testing the build packages and for patchelf I am confident that we do not use it at all.
But cross-python is not working properly atm on apple silicon..unfortunately..since I also have such a device.
This means that setuptools based builds wont work. But Cmake based things build fine on my m2

[tylere]

Thanks for the feedback. Confirming that I am encountering this using Apple Silicon (M1) device.

[DerThorsten]

I got most things working on my M2 with the changes here:

#292
I installed playwright via pip and ignored other missing things.

One then needs to build compilers / cross-python packages by hand, as we only have linux variants of them on emscripten-forge atm:

python builder.py build explicit recipes/recipes/emscripten_emscripten-32/
python builder.py build explicit recipes/recipes/cross-python_emscripten-32

and then I can build and test emscripten-32 pkgs locally with:

python builder.py build explicit recipes/recipes_emscripten/regex  --emscripten-32

it should then compile and at the very end you should see:

@DerThorsten, thank you for the fantastic work around M1/M2 compatibility. Unfortunately, having installed the emforge conda environment (with playwright through pip), running:

python builder.py build explicit recipes/recipes/emscripten_emscripten-32/   

on my M1 MacBook returns the error:

Traceback (most recent call last):
  File "/Users/michaelweinold/github/emforge-recipes/builder.py", line 3, in <module>
    from boa.pyapi import py_build
ModuleNotFoundError: No module named 'boa.pyapi'

[DerThorsten]

the best thing to do is usualy just check what we are doing in the ci =)

we use a particular branch of boa

https://github.com/emscripten-forge/recipes/blob/main/.github/workflows/build_recipes.yaml#L83

🫡 apologies, I missed the @python_api part of the

python -m pip install git+https://github.com/DerThorsten/boa.git@python_api --no-deps --ignore-installed

command!

[DerThorsten]

no worries..this all very complicated atm =)
