Does installing the Debian package using Alien work?

[tawera]

I tried using alien to create an rpm to install to Fedora 33, it worked except the buildspec includes /usr/bin and other already existing paths, which causes the installation to fail. This seems to be a common issue with alien that can be solved using rpmrebuild and removing these from the spec file.

After that it installed successfully and the stl-thumb command works. No thumbnails are generated in nautilus though, and there are corresponding entries in ~/.cache/thumbnails/fail/gnome-thumbnail-factory. I'm not sure were to continue debugging this though, so I'm just posting my findings here for now.

I tried to build master and I copied stl-thumb to /usr/bin/ and stl-thumb.thumbnailer to ~/.local/share/thumbnailers/ Running nautilus with RUST_BACKTRACE=1 G_MESSAGES_DEBUG=all nautilus and trying to generate thumbnail it failed with:

Yah the master branch is currently a little broken right now. That's why I haven't pushed out a new release yet. Try building from v0.4.0.

[janinko]

The tool is working correctly when I use it in CLI from the build directory. I think there will be some issue with the sandboxing.

Anyway I tried v0.4.0 with following error:

May be worth trying again with v0.4.1. https://github.com/unlimitedbacon/stl-thumb/releases/tag/v0.4.1

[unlimitedbacon]

Closing. Reopen this issue if it is still happening with v0.5.0.
