Gupax won't launch

[kurpav00]

OS & Version:

Windows 10 Home, Gupax v1.3.5

Bug

When I try running Gupax.exe, nothing happens. It does not matter if I try launching it by double clicking or in a command prompt. In command prompt, the program simply terminates after a few seconds returning the %errorlevel% 0, but no GUI is opened.

Steps

Steps to reproduce the behavior:

1. Go to the downloaded and unpacked Gupax folder (added among the virus protection exceptions)
2. Double click Gupax.exe (or run Gupax.exe from command prompt)
3. See nothing happening, no errors, no messages, nothing

Screenshots

no GUI opened

Can you see if using v1.3.3 works?

[kurpav00]

Yes, v1.3.3 works. V1.3.4 and 1.3.5 don't. Thank you.

Hello can you try my fork ? specially for windows it is using a different backend for rendering (glow instead of wgpu) and it's using more up to date deps. Let me know if it works for you.

[kurpav00]

@Cyrix126 I tried both the version 1.0.0 and 0.1.10, but none of them works, demonstrating the same behavior - the program does not launch at all, returning the exit status 0.

@kurpav00 ,
Would you like help me debug your issue ? we can talk over matrix or session, whichever you prefer. I will give you a build that will create a log file at runtime. That should help knowing what's going on.

After having the log file, here is the relevant part.

It seems that the cpu is limited to OpenGL 3.1. Maybe glow/glutin is trying to create a context with a newer version. I'll investigate this further.

[Cyrix126]

using wgpu instead of glow output this warning:

WARN [wgpu_hal::gles::adapter] Returned GL context is 3.1, when 3.3+ is needed

[hinto-janai]

@Cyrix126 thanks for investigating this, does this mean CPUs pre-2010 are not supported? Is there a simple fix or is there a tradeoff in supporting OpenGL <3.3?

[Cyrix126]

@hinto-janai you can see a simple fix here Cyrix126@bf74131
You need to bring wgpu dependence with the same version that eframe use and enable the angle feature.
See the issue I mentioned if you want to know the details.
