I switched to Suse Tumbleweed and compiled Ansel on my own.
No problem detected with my previous Suse Leap 15.4 distro.
Now seems Ansel cannot detect Lua on my system so Lua support is not included.
Moreover I receive an error (or advice?) message saying a clang compiler cannot be found despite the fact clang is duly installed on my system and Ansel is compiled and installed.
Can someone help?
Thanks,
Maurizio

Ansel looks for Lua 5.3 exactly, if I recall correctly, it doesn’t accept anything older or newer. But anyway, since the Lua overlay is looking for a binary called `darktable` (it’s hard-coded), it has never worked since renaming to Ansel and that needs to be changed upstream.

Do you know what it would take to get lua scripts working in Ansel?
I really appreciate what you have done with Ansel, and have been wanting to switch to it for awhile. Darktable is now grabbing/stealing global window manager keybindings (super key) and that was a final straw for me.
I’ve grown accustom to a couple workflow related scripts and would like to get them working before jumping fully into Ansel. I’m by no means a developer, but if the required fixes are on the lua side only, I might be able to hack it.
Any pointers would be greatly appreciated.

I have lua 5.4.6 installed on my distro and now Ansel can compile with lua support.
Some scripts works out of the box, other cannot and other (in my case photils.lua) cause a segmentation fault.

Recompiled Ansel right now from sources and lua support disappeared again… sorry…

The default CMake build options don’t enable Lua support by default because Lua is currently wonky (as you saw, some plugins work, some make the app crash). You can manually enable it using CMake options at building.
