Application closes immediately after launched on Linux

[sum-elier]

I am trying to run my application compiled in Ubuntu and I can't get it working. If launched by double clicking the application it just says mentions something like:

there's no application installed for "shared library" files

Event though the file already has execution permission with chmod +x app. If I run it through the console, it appears to work but closes immediately. No GUI interface is shown at all.

I installed a panic hook but there's no panic going on, it closes without explanation.

When compiling and running on Windows it works fine.

Is there any mechanism in Iced to debug this kind of error?

Is there any output? can you paste the error if so?

Can you try running the program with strace and see if it tells you anything interesting?

No output at all in the terminal either. Runs the application, another terminal pops up really fast, and nothing.

Can you try running the program with strace and see if it tells you anything interesting?

I ran it with strace but I am unsure how to interpret the results. Here's a summary, although I am not sure if it is useful:

What should I look for in the full output?

[sum-elier]

@hecrj is there some kind of tracing/logging enabled across the library to allow debugging this issue? Any suggestions?

[hecrj]

@sum-elier The tour uses env_logger.

[ibaryshnikov]

Same here, adding features = ["glow"] helped

[sum-elier]

@hecrj after adding a logging crate looks like the problem is related to wgpu-rs or the Linux version I am using (Ubuntu 20.04/20.10). The error reads: "Could not enumerate physical devices! Initialization of a object has failed"

[twitchyliquid64]

What graphics stack are you using?

[sum-elier]

@twitchyliquid64 Not sure, how do I find out? I am under Ubuntu using X11, is that what you need?

[twitchyliquid64]

Tell us about your window manager, setup, graphics card, paste the output of glxinfo etc

[sum-elier]

Window manager: Gnome 3.38.1
Setup: Ubuntu 20.10 (normal boot and also as guest in VMware)
Graphics card (+driver):

glxinfo output (only for VMware case, should be the same for normal boot): gist

[sum-elier]

@twitchyliquid64 Do you need more information? I've been unable to debug the cause of the problem yet.

[twitchyliquid64]

Does this happen when both booting linux in VMWare and on native hardware?

Can you run it with strace normally and post the output (ie: in a gist). It should be insanely long, but thats good.

Im surprised theres no 'error' of any kind. Usually something will be printed to the console. Or in the case of a graphics driver bug you can hit wierd behavior or lockups.

Yes, it happens in both. Strace of native hardware execution here and for vm execution here

Could this be related to parasyte/pixels#36?

[twitchyliquid64]

I don't think your terminal is working properly, as we can see that the program is trying to print a gfx error to STDERR (fd 3):

0.000101 write(3, "[2020-11-13 20:45:57][ERROR][gfx"..., 125) = 125

Next steps would be to fix your terminal / however you are running it, so you can see what that error message is.

[sum-elier]

I'm pretty sure that it is the previous error:
[2020-11-13 20:45:57][ERROR][gfx_backend_vulkan] Could not enumerate physical devices! Initialization of a object has failed
But, should that be printed to console? I've been dumping that to a file #589 (comment), but only prints that and nothing else

[twitchyliquid64]

Hold up, im mistaken, stderr is fd 2 ... where is that error going?

No idea why its going to fd 3 ...

[twitchyliquid64]

And do you have vulkan drivers installed?

[sum-elier]

And do you have vulkan drivers installed?

Yes I think. I installed vulkan-tools and vulkan-utils. Is that?

[twitchyliquid64]

A quick google suggests nouveau does not support vulkan.

[sum-elier]

Uh looks like that might be the cause. I'll try to compile it in another system with vulkan support

[let4be]

Is it possible to run on Linux inside VMWare(with 3d acceleration on)?
