Here we have GIMP 3 rc3 in AppImage (this is less important).
And I have darkatable in AppImage.
How to tell GIMP “use darktable AppImage” when opening raw file ?
Is the dt appimage in the path?
where to search this path ?
Do You mean environment path ?
Yes
GIMP checks for darktable by trying to run it (with some special flags the darktable developers made for us). So if you can run it in the terminal with just “darktable”, GIMP should pick up on it too.
As You can see in this folder exist file darktable.
This is exactly the same file as file below Darktable *.AppImage
To this folder points environment PATH
export PATH=$PATH:/home/darek/Downloads/Apps/
And I can run darktable in terminal but not inside GIMP.
Try to create a darktable symlink pointing the darktable .appimage file. And don’t forget to append on PATH the place which have the symlink.
