Build from source

[hfiguiere]

@bochecha this is on top of your changes.

It currently fail on Blender that want Python 3.10. Disabling Python al together fail much earlier.

The error I get locally is different, but related to Python as well:

I get some Python errors on startup. Not sure what's causing them though.

[Zenith222]

May I ask what is the point of this change? Blender.org provides trusted binaries which can be verified with a SHA256 or SHA512 hash for security purposes. Building Blender from source on every user's machine is a waste of time and energy for no practical benefit.

this is not happening either. This is not Gentoo. You misunderstand what flaptak does.

Also the second point is to build for aarch64. Baby steps

[Zenith222]

I appreciate the clarification.

it would be nice to have this build tested by people that use this more than I do. (i don't).

Blender does not find my nvidia gpu while the current binary build did. Under Edit>Preference>System>CUDA it say no compatible GPUs found for Cycles. Requires NVIDIA GPU with compute capability 3.0.

closing this. nobody seems to be interested.

Hoping this can be reopened and considered. Would be highly appreciated by the arm64 Linux community.

Hi, I used to be @bochecha but due to reasons I had to create this new @mbridon account, sorry for the confusion.

I used to maintain the flathub Blender build from source, but due to health issues I haven't been able to continue sine 2020, when I got sick. I'm still dealing with the consequences of that disease unfortunately, so I will not be able to come back to building Blender from source.

That means someone will have to be the hero who gets this done again. Maybe you @theofficialgman?

Do note that building Blender from source was a huge beast and routinely took me multiple days of work for each update. I don't see this has improved in the meantime. That is why I'm overall happier with the current solution of using pre-built binaries: at least it gets most users a Blender build in time, even if only for x86_64. :disappointed:
