I have found it does not work really well with Canon RF lenses yet, because all RF lenses have Exif.CanonCs.LensType=61182* and using a .exiv2 file with (for example) 61182=Canon RF 50mm F1.8 STM leads to all RF lenses being identified as Canon RF 50mm F1.8 STM!
(*there is a new Exif.CanonFi.RFLensType field, but I don’t know if/how it is used by exiv2/darktable, and also the (not new) Exif.Canon.LensModel which contains a Ascii name like RF 50mm F1.8 STM)
Using exiv2 0.27.5 with darktable 3.8, my Canon RF 50mm F1.8 STM lens is identified as the F1.2 version and my other lenses are correctly identified.
What I do is import my cr3 files in darktable, then add the .exiv2 file in my /home with [canon] 61182=Canon RF 50mm F1.8 STM, set a collection in darktable with lens=Canon RF 50mm F1.2 USM, refresh exif information for this collection only. The lens is then well defined. I then remove the .exiv2 file.
Not really ideal, but it works. I hope it can help someone else.
Where can i get help? Darktable 3.6.1 works like a charm on my Windows 10 Professional Desktop. Intel i7-7700K 4200MHz on a Asus B150M-C with 32GByte memory.
Darktable 3.8 hangs on startup. The window freezes. There’s just an empty window which i only can close after waiting some seconds.
Deinstalling, reinstalling etc …no change. It just don’t run.
After a couple year hiatus from photography I am getting back into things with a new-to-me Pentax.
DT 3.8 installed great on Ubuntu 20.0.4 LTS after adding the repository. In fact, after running apt update it found libexiv2-27 and offered to upgrade it to 0.27.5-3.1, and afterwards a manual installation of the .deb file works fine, but I re-installed from apt for kicks and grins.
UX is almost identical to the older version I had been using, and it runs very fast now on my newer hardware these days with a Radeon GPU. A big thank you to the devs for maintaining and continuing to polish this marvelous piece of software. cheers
Work perfectly for me. But recall some people had issues. It’s often graphic driver related. You found the right group! You may get more advise with your own topic.
Open a command prompt (press Win + R, type cmd, press Enter)
Change to the directory where it is installed (on my system, it’s at C:\Program Files\darktable\bin).
– Type: c: (or whatever drive you installed darktable on) and press Enter
– Type cd \Program Files\darktable\bin
Launch darktable with full diagnostic logging. Type darktable -d all and press Enter.
You will find a file called darktable-log.txt (substitute your home directory path) has been created: C:\Users\your_user\AppData\Local\Microsoft\Windows\INetCache\darktable\darktable-log.txt
Attach that file to a response here.
Once darktable gets stuck, close it.
Thanks for all of your replies!

Yes. I’ve switched OpenCL off while running with 3.6.1 because i suspected OpenCL to be the reason for the problem.
There is a file called “luarc” in C:\Program Files\darktable\share\darktable
I’ve copied this file now to C:\Users\User\AppData\Local\darktable but that didn’t change anything. Darktable 3.8 still won’t run
I’m not sure how to help you with these issues. I would start by renaming your configuration file to .old and letting the system start a new one when you install 3.8. I’m not sure if your previous settings are causing problems (eg. like looking for lua).
You can also wait to see if someone else has any other ideas.
OK. I don’t see anything critical, but I’m not one of the developers. Maybe opening a new topic would be useful, as the generic “3.8.0 released” topic may not draw much attention.
As for your log contents, I see the “Pango-CRITICAL” messages, but here is someone that also has them, and it appeared to me that their darktable was functioning properly:
I think the
36,149997 LUA ERROR : cannot open C:\Users\User\AppData\Local\darktable\luarc: No such file or directory
line is harmless (that file would exist if you installed Lua plugins, but those are not essential to using darktable).
So, please open a new topic, maybe others will be able to help more. Attach your log there, too.
@MichaJo to follow up on what g-man has been suggesting…
try to run DT with a modified command line… If you are running it from a shortcut then right click select properties and modify the command line to add --configdir “path” where I have typed path enter the path to a new empty folder…now when you run DT it will start from fresh config files…if this is successful or not may provide some more information…
