Package: python3-opencv
Version: 4.2.0+dfsg-6+b6
Severity: normal
X-Debbugs-Cc: none, Dima Kogan <[email protected]>
Hi. I just upgraded my python opencv bindings on Debian/sid:
apt install python3-opencv
This worked. But then this happened:
dima@fatty:~$ python3
Python 3.9.1 (default, Dec 8 2020, 07:51:42)
[GCC 10.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: libcharls.so.2: cannot open shared object file: No such file or
directory
I had libcharls2=2.0.0+dfsg-1 (the current stable release). It called
that library libCharLS.so.2 instead of libcharls.so.2. Upgrading
libcharls2 to the current Debian/sid version fixed the problem. Opencv
should update its dependency.

Hi.
I'd like to not be able to 'apt install python3-opencv' and end up in a
state where this package is now non-functional.
I was thinking you could change Depends: libcharls -> Depends: libcharls
( >= something). But apparently opencv doesn't depend on libcharls (the
dependency is indirect). And the actual bug is in libcharls, fixed a bit
past stable; in 2.1.0+dfsg-2.

I guess it's not worth doing anything in opencv to make this nice. Sorry
for the noise. I'm closing the report.
