Compatibility issue while installing emsdk 1.40.1 with M1 Mac #1327

Open Akash1684 opened 6 months ago

Akash1684 commented 6 months ago

Encountered compatibility issues installing emsdk 1.40.1 on my M1 Mac. The installation process fails with unexpected errors.

Installing tool 'releases-536568644fd67d53778f6111fdd5f64ad3f4c539-64bit'..
Error: Downloading URL 'https://storage.googleapis.com/webassembly/emscripten-releases-builds/mac/536568644fd67d53778f6111fdd5f64ad3f4c539/wasm-binaries-arm64.tar.xz': HTTP Error 404: Not Found
error: installation failed!

I understand there is no precompiled emsdk package for Apple's new M1 macs but wondering if there is any work around to install older version. I have a hard dependency on emsdk version 1.40.1

Update: Tried enforcing EMSDK_ARCH=x86_64 as suggested in link to bypass the ARM check but facing following issue:

I was able to get emsdk v1.40.1 up and running on M1 mac by following steps:

Get the emsdk repo

git clone https://github.com/emscripten-core/emsdk.git

Enter that directory

cd emsdk

Enforcing EMSDK_ARCH=x86_64 in emsdk.py

Update arm64 to x86_64 in line: 148: https://github.com/emscripten-core/emsdk/blob/9347bc393b94a17b93450bbc98bc3f66cef2aeb0/emsdk.py#L148

Installing google-closure-compiler-osx through Rosetta 2.

Steps: https://www.cypress.io/blog/2021/01/20/running-cypress-on-the-apple-m1-silicon-arm-architecture-using-rosetta-2 (instructions are for cypress but works for google-closure-compiler)

Tip: easier would be to use Rosetta with iterm than cloning native terminal

We do have support for M1 macs in emsdk but only with newer versions of emsdk and 1.40.1, which is 3.5 years old, pre-dates that support.

I'm glad you found a workaround.

Can I ask why you have a hard dependency on such an old version? Perhaps we can help you update?

We do have hard dependency on older version because of our testing setup which fails on newer version (2+). The workaround I mentioned works well for us.

Perhaps we can help you update?

Can you help us understand the changes involved?

Can you share the build failures you are seeing when attempting to use newer versions of emscripten? Perhaps close this issue and open a new one in the emscripten repo for that?
