I am trying to install pyobjus in my mac running big sur. I am getting this error while installing.
Here is the error log:

Hi @rajeshmajumdar,

If I'm right, you're on an M1 based device and using the latest version available on pypi.

Can you try to build the master version available here on GitHub?

[rajeshmajumdar]

Same error persists, and it's not m1 based it's intel based mac with latest version of pypi

[misl6]

Is confirmed that while building a universal2 wheel on Intel, (that is now the default on python3.10), the reported error occurs during the arm64 crosscompilation phase.

Hi,
I posted a PR that should fix the issue (#82)

Let me know if it works fine for you.

[rajeshmajumdar]

Thanks @misl6, it worked.
