Oh, yes, the reason why gegl doesn't need those requirements is because I use python to autogenerate C code with data, like curves and color corrections and profiles from measured input data. And upstream to gegl only that C code. But my own repo does not have this commited and instead needs to be generated as a part of the build process.

That's interesting. I haven't checked in my "standard" gimp install whether this project is included before I installed it. If it is, it must be installed as libraries within gimps files somewhere, because otherwise I don't think I would have had to install all the dependencies.

Maybe a closer look at he PKGBUILD of both gimp-git and the official gimp apckage will shed some light on this.


Just checked, and apparently it's included since gimp 2.10.24:

So maybe remove this package altogether? I don't know what the rules for that are :) But at least it's good that we have discovered that installing this package separately is not necessary...

Just fyi, this project has been merged to the gegl upstream and doesn't need to be built separately anymore. If you get gegl-git or even gimp-git, you should see the operation in gegl operation list. And I believe it even got backported to the stable gimp already. So this pkgbuild could theoretically be retired. That's one of the reason I neglected the update. Sorry about the confusion.

OK, I digged a bit deeper and got it working now. It looks like there are dependencies missing, in my case I had to install:


python-imageio and python-colour-science must be installed from AUR. Note that python-colour (available as package) is not the same as python-colour-science!

I hope this helps someone... would be nice if the PKGBUILD would be updated to include these dependencies.

Would love to try this, but I am getting the following error:

==> Starting build()...
script/ -o datasheet/fuji-crystal/paper.json datasheet/fuji-crystal
Traceback (most recent call last):
  File "/home/drtebi/Downloads/gegl-operation-negative-darkroom-git/src/gimp-plugin-analog/script/", line 8, in <module>

    import colour
ModuleNotFoundError: No module named 'colour'
make: *** [Makefile:27: datasheet/fuji-crystal/paper.json] Error 1
==> ERROR: A failure occurred in build().

Any help would be appreciated :)
