Building Blender

Hi

I am following these instructions:

https://wiki.blender.org/wiki/Building_Blender/Mac

but I get an error:

(base) NX-41545:blender mfroehli$ make update
make: /python/bin/python3.10: No such file or directory
make: *** [update] Error 1

I do hav python3.10 installed, but its under a different path:

/opt/homebrew/bin/python3.10

here is the full output:

(base) NX-41545:blender mfroehli$ xcode-select --install

Classic macos python shenanigans. I believe there’s a way to either point path to the right install location or install python in /bin without brew. Iirc there’s quite a bit on stackoverflow about it. Sorry I can’t help more atm.

I just resolved this issue on my Mac. You just have to set the “PYTHON” environment variable to your Python binary path. It will resolve the issue.

Thanks. This solved the issue.

For reference:

I had to add the following line in the file “/Users//.bash_profile”:

export PYTHON="/opt/homebrew/bin/python3.10"

This obviously only works if one has also installed python 3.10 via brew.
