I hope you use different config directories. Also, the XMPs (sidecars) created by 4.7 may not always be compatible with 4.6 (if some module’s parameters have been updated, or you use 4.7-only modules in the edit).
Thanks so much for the answer Bill !!!
It really helped
Hey all … due to my issues with my wrong approach of running DT on my system , I am running again into a " problem " when trying to run both versions .
Talking about the stable and nightly build versions .
As i do not get them running without the database running into problems .
So here is my question … how and where to install the two different versions ?
Can I run them side by side ?
Do I need two different config folders ?
Do I need to give them different names ?
I am just a user that love the program for its outstanding options in terms of raw processing , but I am really dumb when it comes to stuff that is going on behind the program .
The user manual is a nightmare for me , as I do not understand all the fancy programming stuff !!!
So an understandable answer would be great !!
Hope I do not ask for too much …
Cheers Andreas
As @Kofa already indicated, when running two different versions of darktable in parallel you will run into problems (unless you take quite a few precautions).
More specifically:
- sidecar files created with the newer version can be unreadable for the older version (module parameters can change and new modules can appear);
- also, the database scheme can change between versions, again making the older version unable to read the database; the newer version will translate the database to the new version on first run…
So, unless you know what you are doing (and how to avoid and solve the possible issues) I’d suggest you avoid running two versions in parallel (and it’s very easy to make a mistake in this regard). And of course the development version can have transient bugs at any moment (transient; because they are usually caught quickly and corrected).
In that case, I’d strongly suggest you stay away from running development versions (or two versions in parallel)…
It is possible to run two versions, but if you also want to work on the same images with both versions, you are really complicating things. If you still want to try, the manual should have all the info you need.
You’ll have to use the command line, use two separate config directories (command line option --configdir …), and you cannot use sidecar files if you want to use the same image folders with both dt versions.
You may not want to hear this, fair enough.
But this kind of issues is why I stay away from running parallel versions (and I should have the knowledge to do so, just not worth the hassle).
As you already have used the devel version, note that you might be able to recover the old database (from before your 4.7.0 use), as dt keeps old versions with names ending in “-pre-”. But you’ll lose any changes you made with 4.7.0. And if ever you use 4.7.0 again to try it out, the circus starts again.
