Imagemagick cannot process DNG (dng.la file not found)

I have this makefile that converts images. I have not used it for a while but now I try and get an error that I can reproduce as follows
Code: Select all
$ identify dng:image.dng
identify: unable to open image 'dng:image.dng': No such file or directory @ error/blob.c/OpenBlob/3357.
identify: unable to load module '/usr/lib/ImageMagick-7.0.7/modules-Q16HDRI/coders/dng.la': file not found @ error/module.c/OpenModule/1275.
identify: no decode delegate for this image format `DNG' @ error/constitute.c/ReadImage/509.
I have checked and the file is present
Code: Select all
$ ls -l /usr/lib/ImageMagick-7.0.7/modules-Q16HDRI/coders/dng*
-rwxr-xr-x 1 root root 1111 Feb 19 07:54 /usr/lib/ImageMagick-7.0.7/modules-Q16HDRI/coders/dng.la
-rwxr-xr-x 1 root root 15200 Feb 19 07:55 /usr/lib/ImageMagick-7.0.7/modules-Q16HDRI/coders/dng.so
I have checked and confirmed packages are up to date:
Code: Select all
$ pacman -Qo convert ufraw dcraw
/usr/bin/convert is owned by imagemagick 7.0.7.23-1
/usr/bin/ufraw is owned by gimp-ufraw 0.22-11
/usr/bin/dcraw is owned by dcraw 9.27.0-1
My system was last updated yesterday. Any ideas what may be causing this?

Looks like you are now using version 7 and the convert command has changed to magick.
Also I think identify now needs to be:
May not be your problem but something to bear in mind

Well I never knew that
But I do get the same problem with "identify" and "magick identify". I also tried with version 6 and also had the same problem. FWIW I didn't intentionally update to v7 but with Arch, being "bleeding edge", that's what happened
Code: Select all
$ identify dng:image.dng
identify: unable to open image `dng:image.dng': No such file or directory @ error/blob.c/OpenBlob/2761.
identify: unable to load module `/usr/lib/ImageMagick-6.9.9/modules-Q16HDRI/coders/dng.la': file not found @ error/module.c/OpenModule/1303.
identify: no decode delegate for this image format `DNG' @ error/constitute.c/ReadImage/504.

Did you build IM yourself? If so, what does config.log say about the build? In particular, what does it say about libraw?

No, I installed the Arch Linux package.

That's a surprise as a lot of Linux distros are still on 6.7 and in some cases 6.5 although they are usually patched.

I've been trying to get to the bottom of this unsuccessfully.
I have checked my delegates.xml file:
Code: Select all
$ grep dng /etc/ImageMagick-7/delegates.xml
<delegate decode="dng:decode" command=""ufraw-batch" --silent --create-id=also --out-type=png --out-depth=16 "--output=%u.png" "%i""/>
I have manually executed the command-line configured in the delegate:
Code: Select all
ufraw-batch --silent --create-id=also --out-type=png --out-depth=16 --output=temp.png raw_test_16.dng
and I can identify the resultant png:
Code: Select all
$ identify temp.png
temp.png PNG 5084x3848 5084x3848+0+0 16-bit sRGB 95.4144MiB 0.000u 0:00.000
So, from what I can see, the dependencies are in place but use through my imagemagick fails.
Code: Select all
identify dng:raw_test_16.dng
identify: unable to open image 'dng:raw_test_16.dng': No such file or directory @ error/blob.c/OpenBlob/3357.
identify: unable to load module '/usr/lib/ImageMagick-7.0.7/modules-Q16HDRI/coders/dng.la': file not found @ error/module.c/OpenModule/1275.
identify: no decode delegate for this image format `DNG' @ error/constitute.c/ReadImage/509.
The debug output shows likes like these:

The file definitely exists:
Code: Select all

/usr/lib/ImageMagick-7.0.7/modules-Q16HDRI/coders/dng.la: libtool library file, ASCII text
I tested again and see the same results with versions 6 and 7 of ImageMagick.
