RPI linuxaarch64

[dimitre]

I've finally took some time to test things on a RPI 4, latest os
Here is an apothecary PR with partial changes needed to make it run
openframeworks/apothecary#233

and pushed some more changes to this PR related to the core
#7069

here is the list to complete the task if no other issues arise

• update apothecary to build libs in aarch64 - RPI - prepare to aarch64 (bullseye) apothecary#233
• update core to compile in aarch64 - Draft: RPI aarch64 — Debian GNU/Linux 11 (bullseye) #7069
• solve compiler issues (ABI Settings)
• add aarch64 to the libraries deployment system. CI build libs for linuxaarch64 to work with RPI 4 apothecary#269
• it would be great to have this also - Native windowing for Raspberry Pi 4 #6713
• test everything in a fresh OF install

I'm now compiling in an RPI4 machine and it takes a long time to compile everything and test,
so this PRs merged can help
#7426
openframeworks/projectGenerator#331

ABI Issues are gone from Core, but now appearing on AssimpModelLoader. Any ideas @ofTheo @danoli3 ?

/usr/bin/ld: /home/pi/ofw/addons/obj/linuxaarch64/Release/ofxAssimpModelLoader/src/ofxAssimpModelLoader.o: in function `ofxAssimpModelLoader::initImportProperties(int)':

Hmm those functions in assimp are 3 years old so should be present on a 64bit Pi OS.
Do the linker/ld flags show assimp being linked?

Can you do:
dpkg -l libassimp-dev

[ofTheo]

@dimitre - the libs are now up on apothecary 🎉
https://github.com/openframeworks/apothecary/releases/download/nightly/openFrameworksLibs_master_linuxaarch64.tar.bz

Going to make sure the nightly is packaging the aarch64 now - if you wanted to test the above in your RPi 4 - that would be amazing.

[dimitre]

That was fast! Yes let me know when they are there. I'll test a fresh ofw install on a rpi4

[ofTheo]

Here you go @dimitre 🤞

#6692 (comment)

[ofTheo]

Oh. Hmm. Is it missing ofxOpenCv from addons.make? Or do the examples in computer _vision/ not work either?

[dimitre]

it is in addons.make. I think examples in computer_vision don't work. I can confirm early tomorrow

[ofTheo]

I thought this error looked familiar - I remember seeing it on the CI when switching to 22.04
See:

Do you see any warnings or messages about harfbuzz being missing?

Either way it might be good to try and install:

            sudo apt-get install libharfbuzz-dev -y;

And see if that fixes it?

If so we should probably add it to the Ubuntu and Arm install scripts
