Failing to install glslViewer on Raspberry Pi OS Lite

[murilopolese]

I'm have the "lite" version of Raspberry Pi OS installed in a Raspberry Pi 3.

Am I trying something crazy? I'm finding the following problems:

• glslViewer can't be found on apt
• Can't add the ppa
• Compiling from the source will fail like this:

...
-- Check size of unsigned short
-- Check size of unsigned short - done
-- Searching 16 bit integer - Using unsigned short
-- Check if the system is big endian - little endian
-- package_details.cmake: your architecture is armhf
-- Configuring incomplete, errors occurred!
See also "/home/pi/glslViewer/build/CMakeFiles/CMakeOutput.log".
See also "/home/pi/glslViewer/build/CMakeFiles/CMakeError.log".
make: *** [Makefile:3: default] Error 1

• Installing from the release files (without X) will fail like this:

./bin/glslViewer: error while loading shared libraries: libopenmaxil.so: cannot open shared object file: No such file or directory

The weird thing is that I had this running on a Lite distro earlier this year... :scratching_head:

hi! yes, the PPA it's out of date and I haven't send an updated version to the folks at Raspberry Pi. Sorry for that.

Your best option is to compile from source I think. In this link you will see the required steps for Raspberry Pi https://github.com/patriciogonzalezvivo/glslViewer/wiki/Compile-on-linux.

Question, are you using a RPi 4? or Zero, 3 or 3+?

[murilopolese]

Thank you for the reply, @patriciogonzalezvivo !!

This is a bit funny because I did write a bunch of shaders with a raspberry pi setup (Pi 3) a few months ago following this video: https://www.youtube.com/watch?v=7lXYPfoOdAU

The error I printed above is the error I get trying to compile from the source. I followed both the instructions with and without X11 and it's the same. I haven't tried with the Ubuntu dependencies...

Question, are you using a RPi 4? or Zero, 3 or 3+?

I'm trying on a Raspberry Pi 3 but trully I was thinking about giving a purpose for the 9999 Raspberry Pi 1 and 2 that I have here collecting dust 😂

I also have the apt issue fwiw - might be work noting on the readme PPA instructions that compilation is likely mandatory.

sudo add-apt-repository ppa:patriciogv/glslviewer-ppa

So far compilation on Raspian OS (latest as of this writing setup (not the lite variant, the full desktop) appears to be working

Interesting. Doing a build with

cmake -DNO_X11=TRUE ..

results in

I attempted to follow the instructions for no X11:

sudo apt install git cmake libegl1-mesa-dev libgbm-dev libgles2-mesa-dev

which results in this cmake error:

Wondering if this is a change on the last OS and their support to MMAL. I will get the latest OS and try to replicate the issue. My guess is that the cmake files for it need to be updated. Sorry for the troubles.

As per our twitter convo -Looks like enabling the legacy camera system and re-starting build by clearing build folder re-running cmake still errors when using cmake -DNO_X11=TRUE .. - same error as before:

if its easier, im happy to revert to an older raspian OS before this camera and MMAL shit?

[patriciogonzalezvivo]

Yes, that seams the easiest path until figuring out a new strategy is to install Buster (Legacy).

Articles that explains the changes on Bullseyes:

• https://www.raspberrypi.com/news/raspberry-pi-os-debian-bullseye/
• https://qengineering.eu/install-gstreamer-1.18-on-raspberry-pi-4.html

Other projects that are experiencing the same issues

• motion: Pi camera not functional on Bullseye  Motion-Project/motion#1434
• picamera: picamera.exc.PiCameraMMALError: Failed to create MMAL component b'vc.camera_info': I/O error waveform80/picamera#697

In conclusion, I will make OpenMAX and MMAL textures support optional instead of default for Raspberry Pi and work on support for libcamera ( https://www.raspberrypi.com/news/an-open-source-camera-stack-for-raspberry-pi-using-libcamera/ ) which seams to be what RaspberryPi move towards. This changes will be made on ADA ( https://github.com/patriciogonzalezvivo/ada/tree/main/include/ada/gl ) and then updated to glslViewer once it's done. Mean while please use the legacy OS.

[vade]

Awesome. Thanks Patricio. I really appreciate the assistance. Im going to try Legacy now and ill post if things are working if you don't mind!

[vade]

Hrm. Seems like latest ADA is causing an issue ?

I see cmake -DNO_X11=TRUE -DFORCE_GBM=TRUE .. - I didn't realize I needed both.

[vade]

Ok, sorry for the play by play, and apologies for taking over the git issue @murilopolese !

Compilation with cmake -DNO_X11=TRUE -DFORCE_GBM=TRUE .. works, but execution fails with Assertion 'EGL_FALSE !=result" failed

[patriciogonzalezvivo]

Are you using a RaspberryPi 4? or 3, 3+ or Zero?
try running glslViewer with --display /dev/dri/card0

I'm working on a easy fix for the LEGACY vs GDM modes

[vade]

I'm using a RPI 3 B. I was able to get it working with no X11 with no Fake_KMS and I didn't realize the config had a special api only section. Sorry im a newb :P

It might be helpful to make a matrix of RPI models, required configs, OS versions (legacy or not) and cmake flags.

Thats a lot of work but im happy to help document / try stuff out! Thanks for all the help.

FFMPEG installed as per wiki
Compiled with No X11

Boot into console,
No Fake KMS
Camera enabled

However HDMI is the wrong resolution (its not an under-scan issue) but camera is working and this is way faster than the old Open Frameworks

YAY!!!
YES please I accept any kind of help regarding documentation : ) The entire legacy BROADCOM drivers vs the DRM/KMS/GDM it's a mess!
The display through /dev/dri/cardX it's a DRM/KMS issue. BROADCOM legacy drivers don't require it.
HDMI resolution can be fix on /boot/config.txt
What screen are you using?

Thanks. I just got it. its weird because the newest (non legacy) didn't require me to guess at the display size. Oh well. I have the Adafruit HDMI backpack and was able to edit the config

# uncomment to force a specific HDMI mode (here we are forcing 800x480!)
hdmi_group=2
hdmi_mode=87
hdmi_cvt=800 480 60 6 0 0 0
hdmi_drive=1

and it seems to be just working.

OMG! that's already exciting! I'm also excited for improving ada/glslViewer to fit your needs. While we speak I already isolate MMAL/OpenMAX libs only for LEGACY OS / on NON-X11 and NON-FKMS so people can keep compiling glslViewer while I work on libCamera support. But seeing your result already bring some peace to my heart that I'm not blocking you

[vade]

Haha thanks! Didn't mean to be pushy, I just can see how helpful GLSLViewer will be to actually playing with creative output and not fucking around with other stuff, so getting it working was tantalizingly close and you know how stubborn I can be. Now on to the fun shit like remembering how to code shaders ;)

[patriciogonzalezvivo]

Lol! Man I'm really excited/honored of you using my tools. It's like having people over, I want you to be comfortable and feel just at home. Excited to see what you do with it and what other hard-edges we can sand

This thread is the best @vade ❤️ ! Thanks for jumping in.
It's so nice to read your words about how you feel when people use the tool @patriciogonzalezvivo!

I'm away until early January, but I'm looking forward to try the downgrate to the legacy OS and the configuration stuff.
Thank you so much you all! 🥳

[patriciogonzalezvivo]

Good news, if you pull and compile again should work. The support for camera still pending but should compile now : )
