Unable to install dependencies using install_deps.sh for compiling blender Raspberry Pi 4

When I try to install dependencies for compiling blender, why do I get the following error:

Unpacking OpenColorIO-1.1.0

I am running this on a Raspberry Pi 4 (4GB) (armv7l - 32 bit) Raspbian Buster

have you managed to solve this problem?
i m trying also at the moment to build Blender 2.80 on a RPI4, and i m having the same issue

@TaOuch No, I still haven’t found a solution. But, I think now Blender 2.8 is available on steam and also on snap store (but still for amd64 though). May be we can try installing from these sources if possible.

ok. i will not be able to check it for a week now. but i ll def try after.
i wouldnt want to be pessimistic, but there is low chance - almost to none - that a build an amd64 will work on an arm cpu. they have different instruction set.
i ll come back to you in a week tho :slight_smile:

The issue is in building OpenColorIO. I suggest to run install_deps.sh --skip-ocio to disable it for now, and disable any other libraries that give issues. Then once you have that building you could try to get everything working.

is it possible to compile Blender on ARM64 now? have you try in success?

No. Sorry. I have not managed, and then i gave up.

Debian and Arch repositories have ready-made binary packages available, but I do n’t know how they are compiled and generated. Even if the compilation is successful, the only available method at the moment is only cycles rendering, because most ARM architecture SOCs do not support OPENGL Can’t open UI, only command line cycles rendering

For Arch packages you can easily lookup the PKGBUIlD script in the package repository. For the Rpi version of blender the script can be found here: https://archlinuxarm.org/packages/aarch64/blender/files. For more info on how to use this check out the docs for the AUR (Arch User Repository), especially the makepkg tool
