Hi!

I'm getting an error during compilation due to something called "QColorSpace".

make: *** [Makefile:373: .obj/qjpegxlhandler.o] Error 1
Failed to build libqjpegxl.so

I'm running Kubuntu 20.04.

  • I compiled and installed libjxl without any errors, and cjxl+djxl work without any issues.
  • I checked that the image-jxl.xml file is in the right directory, then updated the mime database.
  • Couldn't find the "qt5base-dev" package, but I found and installed "qtbase5-dev", which at the time I assumed is the same.
  • Then cloned the code with the --recursive option.
  • When building after this, I get the above error message.

Am I missing some dependencies? Or is qtbase5-dev the wrong package after all?

Edit: I forgot to mention that I managed to compile libjxl without errors and it works without any issues.

This plug-in needs at least Qt 5.14

I think that Kubuntu 20.04 has only Qt 5.12.8 so it will not work.

Alright, installing qtbase 5.14.2 did the trick. It works without any issues now.
Thanks!
