$ mcomix foo.cbr
10:44:31 [MainThread] ERROR: You don't have the required version of the
Python Imaging Library Fork (Pillow) installed.
10:44:31 [MainThread] ERROR: Installed Pillow version is: 10.0.0
10:44:31 [MainThread] ERROR: Required Pillow version is: 6.0.0 or higher

What is one supposed to do with an error message like this?!
I even uninstalled pillow and then re-emerged mcomix. Sure enough, it
pulled pillow, as expected. No avail.
Thanks

Something that starts with a 1 is smaller than something that starts with a
6.

Had a lot of trouble with mcomix when I tried it sometime in the last
few years. If you already have most of the dependencies I can
recommend trying app-text/evince as an alternative. It works fine in
my limited usage.

I've been using mcomix without problems. This is something new (I update my
system weekly and only noticed this problem today; well, I don't use mcomix
every week, but even so...)

Nope. I don't run a Gnome system, and evince pulls an absurd bunch of
dependencies, even with most USE variables unset ("absurd" as in: why would
I need elogind, udisks, polkit, etc. just to read a comic book or view a
pdf?). By the way: zathura works fine, with very few dependencies, and
reads comic books, as well as pdf/djvu files. But it doesn't offer that
handy index sidebar with thumbnails.

Thanks,

Jorge

Sure, which is why I put in that caveat :)

I do have elogind because sddm requires it (have been pondering if I
should switch), but I don't have udisks or polkit, so those can at
least be controlled with some USE variables.

Yes, I understood what you meant. I was just saying that I don't have most
dependencies installed.

That's curious. I just tried emerge -p evince with all USE variables unset
and it refuses to comply. Some dependencies suffer from "unmet
requirements". Never mind. evince was made for Gnome users, which I'm not.
I'll wait to see what gives re mcomix... (For viewing files for which a
thumbnails-based index is not a must I'll just stick with zathura.)

There's also for example qcomicbook, if you have Qt on your system.


But this really looks like something to be fixed on the mcomix side. It
has already been fixed in version 2.2.0:

    https://sourceforge.net/p/mcomix/git/ci/master/tree/ChangeLog

If I'm reading correctly, 2.2.1 is in the tree, so you could see if
unmasking that one before it gets stabilized is a possibility.

The relevant change appears to be:

https://sourceforge.net/p/mcomix/git/ci/04785a835b6c0e0782c9d0689686b0c1139febb1/tree/mcomix/run.py?diff=ae7d6a03f001de3241e586b1b285ce624383f344

from https://sourceforge.net/p/mcomix/git/ci/04785a835b6c0e0782c9d0689686b0c1139febb1/

(Which might be useful in case you want to try to add a patch to the
version you currently have installed)

Yes, I have QT and qcomicbook emerged just fine (no dependency forest).
However, I found it useless: the menu lacks entries for custom zoom (I
mean, something like "+" and "-" that similar software offers). This is a
party killer for me.  Maybe it's hidden somewhere...
Anyway, I solved the problem by installing the current version of mcomix
from the sourceforge site. That would be version 2.3.0, whereas the
"stable" version in gentoo is 2.1.0!
(mcomix allows installing as non-privileged user in ~/.local/, hence it
does not conflict with portage. No dependencies needed to be installed, I
guess an up to date gentoo system alfready has what is needed.)

Thanks

Jorge
