[bug] core dump upon startup on Linux

[bard]

Describe the bug

$ ./Onlook-x86_64.AppImage

(process:477913): Gtk-ERROR **: 09:21:13.411: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported
Trace/breakpoint trap (core dumped)

Haven't investigated in depth but here's the same issue in logseq. It doesn't reference the fixing commit explicitly but looking at the date I think it's this one.

[Rish-it]

Hi @bard, thanks for the detailed bug report! Could you provide some additional info:

• What Linux distribution are you using?
• Which version of the Onlook AppImage did you download?
• Can you share the output of ldd ./Onlook-x86_64.AppImage?

I'm investigating this GTK conflict issue and any additional details would help.

[bard]

Hi @Rish-it, I'm using Arch. I downloaded the AppImage from https://onlook.com/download, I don't see a version number, md5sum below:

$ md5sum Onlook-x86_64.AppImage 
c006d34d6aa0656404f7a6314a5058a8  Onlook-x86_64.AppImage
$ ldd Onlook-x86_64.AppImage 
	not a dynamic executable

[Rish-it]

@bard Thanks for sharing the details this needs little more debugging. This is most likely the conflicting issue form GTK as you attached in the first shot

# Check for conflicting native modules
npm ls | grep -E "(gtk|cairo|pango|gdk)"

# Remove any old GTK-related native deps
npm uninstall any-gtk-related-packages

# Clean node_modules
rm -rf node_modules package-lock.json
npm install

I’d recommend getting rid of multiple GTK versions, and double-checking that your Electron version is compatible with the native modules you’re using. After that, try rebuilding.

Let me know how it goes — happy to help further if it’s still giving trouble!

[bard]

@Rish-it in which directory are you suggesting to run those commands?

[Rish-it]

Version checks can be done in your default terminal

[bard]

"Directory" as in folder. In which folder are you suggesting to run those commands? A clone of the onlook repository?

I've got the same issue with latest build

(process:16421): Gtk-ERROR **: 03:31:24.959: GTK 2/3 symbols detected. Using GTK 2/3 and GTK 4 in the same process is not supported

I'm assuming we should try to build from source and see if those happen there?

Edit:

When I ran it via bun dev, I get:

npm ls | grep -E "(gtk|cairo|pango|gdk)"
