AppImage does not run on Ubuntu xenial

[probonopd]

Hi, thanks for making an AppImage. However, it does not run on Ubuntu xenial:

Please see https://github.com/AppImage/AppImageKit/wiki/Creating-AppImages/cc2441518975caca23e9ce2dba6f08a22c678d1e#creating-appimages-that-are-compatible-with-many-systems.

Hey, as Scintillator is designed as an extension to SuperCollider it makes sense that it would run in any many places where SuperCollider runs as is reasonable. So agree it should work on Xenial. As this is a pre-alpha release of the software I'm currently prioritizing features and issues encountered by developers who are testing the product. But I'll add it to the Beta release blocking list.

[lnihlen]

The build server now runs Xenial instead of Bionic. The basic integration test suite has also been ported to Xenial and the build is passing those tests. Marking this as closed. Please do re-open if the 0.0.8 release has issues on Xenial.

[probonopd]

Thank you very much @lnihlen. Where can 0.0.8 be downloaded? I can't seem to find it on https://github.com/ScintillatorSynth/Scintillator/releases.

[lnihlen]

The official release of 0.0.8 will happen at the end of August, or thereabouts. But here's a link to a version of 0.0.7 built on Xenial, if you'd like to try it out before then.

Still getting

[lnihlen]

Oh, sorry, sent you the wrong build. I've had to change how this app is developed after learning a bit more about how Quarks are distributed. That's still a pre-Xenial build. It looks like builds right now on the develop branch aren't being uploaded. I can re-open this bug, then ping it again when the patch has been merged back into master.

[lnihlen]

I fixed the build server issues on the develop branch, here's a build that should work on xenial:

[probonopd]

Getting better... now we are down to

Are you using a newer C++ compiler than what comes with xenial?

[lnihlen]

Yes, the build installs g++-7 from the ubuntu-toolchain-r ppa. Scintillator is written in C++-17, and the version of gcc on xenial seems to pre-date that standard. Here's the AppImage construction from the build log below. I note several libraries are on some kind of blocklist and aren't being included - is there a way to request their inclusion?

Alright, I'll give it a go once I've completed the current PR I'm working on. Reading through that documentation I have some concerns because I'm already using a custom AppRun script, so I hope I'm able to combine the two together without too many contortions. Is there a way to trivially replicate your testing setup? Some stock Ubuntu Xenial image on a VM?

Yes. Or a xenial Live ISO.

I've tested the build at https://scintillator-synth-coverage.s3-us-west-1.amazonaws.com/builds/scinsynth-63f9b53d7a8fe381b7b2e4db79c23f3c2ae6c8df-x86_64.AppImage on a stock Xenial virtual machine. If you get to a console log error message that it can't find the Scintillator quark directory, then it's loading correctly. For a more complete test you can pass --quarkDir=<path to Scintillator checkout> --swiftshader as command-line arguments, but you will need to check out the Scintillator repository for that to work.

The binary loads a bunch of metadata from yaml files in the checkout and needs it to run. The --swiftshader command tells the system to use the software Vulkan renderer (as opposed to hardware acceleration). I haven't investigated but I imagine the state of Vulkan hardware drivers on Xenial is either absent or deprecated. If you get to a window rendering a black screen than it's working correctly and is waiting for OSC commands to execute.

Thanks for bringing this up and all the feedback. I sincerely hope this resolves the issue! :)

Thanks, it is working now. :+1:
