Error runing on Ubuntu 18.04

How to run uad on Linux? The README.md doesn't actually say. I tried making it executable and running like a shell script but got the following errors. ADB is installed and working.

~/Downloads$ ./uad_gui-linux

The error say that wgu can't create a Vulkan instance. You need to make sure Vulkan is working on your computer.

If you don't care (or your CPU/GPU is too old) you should just use the OpenGL build of UAD.

Thanks for the reply. my PC is very old, CPU is Pentium T4400 with integrated graphics. I tried with the OpenGL build and got different errors.

~/Downloads$ ./uad_gui-linux-opengl
thread 'main' panicked at '0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

Looks like I have a missing dependency. Do you know which package provides the needed GLSL version?

Thanks

This is an upstream issue. Very old hardware with only GLSL 1.20 is currently not supported by Iced (see #931)

Someone fixed the issue in their fork but it wasn't merged in Iced master branch. I'll see if @dvdsk can sync their fork with Iced master so that I can release a special build for you :)

Does this build work for you?

If not, try this one.

Don't forget to tell me what build worked for you.

Thanks, both versions fail to run with the errors:
/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./uad_gui-linux-legacy)

/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by ./uad_gui-linux-legacy2)

Oh. Okay. Ubuntu 18.04 is stucked to v2.27 glibc.

I need to compile UAD from a Ubuntu 18.04 docker image. I'll do it tomorrow.

Do you stay on Ubuntu 18.04 because it is still supported and you don't have any reason to upgrade? I advice you to upgrade to Ubuntu 22.04 LTS when it will be released. There has been a lot of performance improvement since 2018.

Thanks, I stay on 18.04 because it's very stable on this hardware and everything I need works. I tried 20.04 but WiFi was broken. I spent a couple hours trying to fix it, gave up and went back to 18.04. I will try 22.04 next year.

That's understandable.

Hopefully it works now : uad_gui-linux-legacy

Success! Your latest version works on my ancient hardware and old distro. Thank you.

Good news! Iced now officially supports old hardware with only GLSL 1.20! This means I don't have to maintain a special build for those hardware anymore!
