Information

• OSX Catalina 10.15.6:
• Build from source):
• Information from command copy-system-information:
  • Nyxt version 2.0.0 (git hash decfe51)
  • Lisp: SBCL 2.1.4

I'm building with NYXT_RENDERER=qt.

[jmercouris]

Qt will not build under current master. Latest supported version is ~1.5. We would need to bring it up to date! In the meantime, there is hope at least for WebKitGTK+, they are making progress for it on NixOS. Sorry about the problem!

On WebKitGTK+ side, MacPorts doesn't provide WebKitGTK+ >= 2.32.0. Older versions are insecure.
I failed to build WebKitGTK+ 2.32.1 from source on my Mac. (omitted what happened....)

Anyway, it seems that Nyxt is not safe with WebKitGTK+ on Mac for now, while qt version doesn't work either.
Which is the next step to do? Shall we move qt version up to date first? Or shall we solve the WebKit compatibility on Mac?

Shall we use Clozure CL and apply its interface to Webkit for Mac version rather than GTK+ port version of Webkit?

Shall we use Clozure CL and apply its interface to Webkit for Mac version rather than GTK+ port version of Webkit?

If I'm not mistaken, this is how early Nyxt versions (Next back then) used to work.
macOS' WebKit API is very limited though, it didn't cut it for Nyxt, which is why we had to move to WebKitGTK.

Shall we move qt version up to date first?

This is very high on my priority list. It takes time and effort, so a helping hand is always welcome :)

About WebKitGTK: It's unclear whether Brew or MacPorts will fix the package, but things are moving on the Nix front: NixOS/nixpkgs#126082.
This is probably our best shot.

I'm having the same DIVISION-BY-ZERO problem, when calling newQApplication. Calling it directly from C (by building interface.cpp as a executable) however works, weird.

Update: this problem is exclusive to SBCL. Clozure CL does not have this specific problem.

See #577 for a discussion on how to pursue macOS support.

Nyxt plans to support macOS in version 4.0.0.

Stay tuned @svetlyak40wt, your feedback will be very welcomed. Thank you for your work in the CL community.
