SUMMARY I am using RawTherapee and Digikam, both as AppImages under Ubuntu 19.10. Openening RawTherapee as a ImageEditor does not work, the ImageEditor stays more or less empty. The tools itself work, but the connection using the new option in Digikam 6.4 seems not to be able to find the RawTherapee AppImage. I even allowed RawTherapee at first start to register itself as an Application within the Launching App of Gnome. STEPS TO REPRODUCE 1. Install RawTherapee and Digikam as AppImage 2. Choose RawTherapee as Raw Import Tool 3. Open the Editor OBSERVED RESULT Nothing happens, RawTherapee does not get triggered. EXPECTED RESULT It should open RawTherapee to do my RAW File adjustments. SOFTWARE/OS VERSIONS Linux: Ubuntu 19.10 Gnome ADDITIONAL INFORMATION Discussed this issue already on https://discuss.pixls.us/t/make-digikam-work-with-rawtherapee-both-appimages/14956 And it seems there is something similar with Windows and RawTherapee https://bugs.kde.org/show_bug.cgi?id=414340
Both programs in AppImage format - nice. That too works. DigiKam looks only for the program "rawtherapee". So a symbolic link has to be created, in the way: ln -s /path/to/appimage/RawTherapee-releases-5.7-20190910.AppImage /usr/bin/rawtherapee Maik
Just wanted to add that there is help offered here in case you need it: https://discuss.pixls.us/t/make-digikam-work-with-rawtherapee-both-appimages/14956/6?u=andrius Apparently Dr Raw has figured out how to call one appimage from within another.
The digiKam AppImage can call external programs, we already adjust the environment variables. My solution from comment 1 works here under openSUSE with 2 AppImages without problems. It would be nice if someone tested it on Ubuntu. Maik
I tried crating the symlink. But it is not opening RawTherapee, even though the symlink itself works if executed from command line. I installed RawTherapee from the repo and with the one from the repo everythin worked. Anyohow in /user/bin the installed repo RawTherapee version created two entries rawtherapee rawtherapee-cli Or Digikam uses another binary link on ubuntu to execute RawTherapee. But yes AppImages do have the benefit of being up to date, otherwise I would still be using digikam 5.9 on my ubuntu 19.10 installation ;) and rawtherapee 5.6 Thanks for any help.
The output from the console could be of interest when digiKam AppImage tries to launch RawTherapee AppImage (the symbolic link must exist). Maik
I tested it today once again, and magically it worked. I have no clue if installing RawTherapee from the repo made some changes, but after I removed it, and recreated the symlink it works. If I have time I am trying the setup again with an VM and a clean Ubuntu, but on my machine RawTherapee gets triggered by Digikam using the symlink in /usr/bin/
