xnView warning: directory permissions differ, then segmentation fault

anselm · 2016-10-24 03:38:50

I tried to install xnViewmp from the git repo. After issuing "makepkg -s" in the cloned git directory, the package is made, while installing it, warning messages appear:

warning: directory permissions differ on /opt/xnviewmp/UI/
filesystem: 755  package: 700
warning: directory permissions differ on /opt/xnviewmp/UI/icons-48/
filesystem: 755  package: 700

when trying to run the application, I can see:

$ xnviewmp
bash: /usr/bin/xnviewmp: Permission denied

after:

sudo chmod 755 /usr/bin/xnviewmp

segfault appears:

$ xnviewmp
Segmentation fault (core dumped)

What can be wrong? xnView worked a few weeks ago.

The git repo sets owner rights only (single user installation, it seems), but that's likely not related to the segfault.
run xnview in gdb and dump a backtrace.

inb4: you're not on gnome on wayland, are you?

No, I am using Xfce as I have a low end PC, 2 GB RAM, P4.

Ok, then will require a backtrace (notably the xnview developers ;-)

Hi, same problem here on Manjaro.
the backtrace looks like this:

Please contact manjaro

But that's not a backtrace, but a (pretty unspecific) python exception and xnview doesn't depend on python, so I don't understand how that could be related?

quiniouben · 2016-11-26 13:44:09

SOrry yep sure, the trace is not very meaningful, but that's the output of gdb (which runs fine on this machine).
xnviewmp is not compiled but binary provided by developers, so well, apart ip and sp, it's hard to get something from it or are the symbols somewhere hidden in the package ?
I know I report here on a manjaro machine, but I am arch linux user too, and I must admit I am surprised to see xnviewmp runs fine on my arch linux machine (64-bit arch and os, no desktop environment, only xmonad window manager) but not on another machine with manjaro (32bit and xfce).
I will try to get more clue and let you know if I reach some knowledge.
