System.DllNotFoundException on Linux

[srid]

On Linux (NixOS), the Desktop project fails to run:

❯ dotnet run
Suave server started
A Phontino window should pop up
That window is running the user interface hosted by webpack at http://localhost:3000
Meanwhile the (Suave) backend is running on http://localhost:5000
Webpack dev server will proxy all HTTP calls to Suave during the development session
Unhandled exception. [03:39:53 INF] Smooth! Suave listener started in 92.608ms with binding 127.0.0.1:5000

Hi @srid, thanks for filing the issue. This is interesting. Seems like NixOS distribution isn't yet supported by Photino? 🤔 I will file an issue on the native Photino repo to track the problem and will keep you posted

On Linux, Photino tries to use WebkitGTK+ which is assumed to be installed on your machine. Can you check that you have that dependency? Otherwise you can install it using

sudo apt-get update && sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev

Though I am not sure this is the right dependency version

[srid]

Gotcha. On NixOS we would also have to tweak the LD variables.

[Zaid-Ajaj]

Did you manage to make it work for your distribution? 😄 Would be awesome to add a side-note of the extra requirements for Linux nixOS somewhere in the docs 🙏

Not yet, but I'll open a PR when I get to that.
