digiKam 8.2.0 is released

Another Linux Mint 20.3 user here. Appimage for 8.1 opens all right, 8.2 does not, or any later releases.

Running in console gives error messages like:

digikam: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /tmp/.mount_digiKayX0pb5/usr/lib/libMagick++-7.Q16.so.5)

Hi @JanisE welcome. It seems that your version of glib is too old.

The error message tells you where the problem is:

digikam: /lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found

That’s a fairly low level library, so you might be able to install it separately (look for something like
libstdc++6). Afaik, that library is not the same thing as glibc, which a C library (and not C++).

Isn’t Appimage supposed to have all the dependencies included?

libstdc++6 is already the newest version (10.5.0-1ubuntu1~20.04)

Sort of. The technical answer is “it can’t”.

AppImage is just an ISO file, what developers put in it is up to them (and they usually don’t do a good job at it).

I use lots of AppImages and they all work nearly perfect.
