I am on Debian Jessie.
I installed gmic for gimp (version 188.8.131.52), in order to use the film emulation filters that come with. So I tried to test one of these filters, but I was unable to do so because the links to the .cimgz files still points toward the old sourceforge direction. Then I downloaded all presets in order to use gmic-gimp offline. So I managed to download the zip file and decompress at $HOME/.gmic_film_presets as indicated.
But then If I try to use any of the filters, it still tries to download the .cimgz files from the broken link and refuses to acknowledge the existence of the files in $HOME/.gmic_film_presets. I then tried to fix the link in the configuration files but I coudn’t find any gmic-gimp configuration file. I don’t know what to do.
