XnView [Solved]

[seppalta]

Installed XnView, but it refused to launch, giving me the error message:  "/opt/XnView/XnView: error while loading shared libraries: libgstapp-0.10.so.0: cannot open shared object file: No such file or directory".  All the gstreamer libraries seem to be installed.  Any ideas?

An idea for the reason, and maybe a solution.
gstreamer0.10 is no longer part of Debian testing repos. It has been substituted by gstreamer1.0.This gave me trouble with Opera 12 on my 32-bit-system a few months ago. Xnview's problem seems to be related to 0.10, too.
According to https://debianforum.de/forum/viewtopic.php?f=29&t=159906 it is sufficient to install libgstreamer-plugins-base0.10-0 from jessie (stable). But this package might have other unmet dependencies or conflicts on your system. I had that problem with Opera and In the end I just modified Opera's dependencies. Don't know whether that works with XnView.

Thanks, py-thon.  I think you are probably right.  I just assumed without thinking (which was dumb) that gstreamer1.0 and gstreamer0.10 were effectively the same.  I'll have a look at the stable 0.10 and report any good results back.

How is Opera working for you?  I'm kind of unhappy with Iceweasel these days.

Downloaded and installed libgstreamer-plugins-base0.10-0 (0.10.36-2) from Debian Jessie (https://packages.debian.org/jessie/libgstreamer-plugins-base0.10-0) and all appears working.

The "real" Opera is still my favourite browser (since 1999) and my only mail-client but due to its age every day there are more pages that can't be displayed properly.
I tried the current Chromium-based Opera two or three years ago and didn't like it. As it was clear that it wouldn't get a mail-client I was also put off.
For pages that can't be displayed in Opera 12 I use Vivaldi (Chromium-based) which is making progress but still lacks several features Opera has, not only the mail-client which is said to be added until the end of the year. Then Vivaldi would be a replacement for Opera.
Another alternative I sometimes use is Otter (in Sparky's repo or more recent versions at https://launchpad.net/~otter-browser/+archive/ubuntu/weekly/+packages). It started nicely but development is slow, so I have doubts whether it will ever get the planned mail-client.
