Cross compilation linux -> windows

[lexxvir]

Hi,

I have tried to cross compile the gallery demo for Windows in the linux host (ubuntu 22.04) using opengl backend.
Compilation have finished successfully with following command: cargo run --target x86_64-pc-windows-gnu
I able to run application under Wine.

But when I run application in Windows 11 there is no text at all:

I have tried both release 1.0.0 and master branch.

This is most likely cause by a bad OpenGL driver. Unfortunately cross compiling the Skia backend won't be possible with mingw. You could try using the software renderer - although you might run into some missing features related to text. Try passing --features slint/renderer-winit-software and set SLINT_BACKEND=winit-software as environment variable when running.

@lexxvir btw, I'm curious: What graphics card & drivers are you using on your Windows installation? I haven't been able to reproduce this issue yet, but I've seen it. I'm interesting in finding out how to reproduce it, in order to assess if there are any easy workarounds.

Hi @tronical !

Thank you for the suggestion about software render. I have tried it but without luck. Issue the same - text is not rendered at all.
I suppose that some fonts are missing probably...

Regarding my env: it is Windows 11 Visual Studio development image for VirtualBox 6.1 that I run in Ubuntu 22.04.
Also, I have tried the same application in real Windows 11 and it works fine!

So probably it is issue with VirtualBox emulation.

Ahh, thank you! VirtualBox rings a bell. That could be it, and that could be the key to reproducing it.

So, I installed recent VirtualBox version 7.0 and now it works! Thank you for the help!
