Linux requirements, installers for non-top-recent distros

[wwp]

Same problem.

[wwp]

And deleting a file doesn't do it either.
And renaming a file doesn't work too (I press F2, type in another name, ENTER, I get a replace dialog w/ half of data not set, whatever I do, the "Copy of" file won't be created).

It seems that we are facing a general and silent failure when renaming/deleting folders and files on a local filesystem (trash used or not). I could get some files to be moved to Trash efficiently on an external disk, though.

is it a ext3 partition?

[wwp]

ext4. I got files deleted as expected on an external VFAT one.
Do you use the Qt primitives for directory/file handling?

i've tried on CentOS6, and no problem

I did some more testing and this time, testing operations on "folders", "favorites" and in the thumbnail view. Formerly, my settings were NOT to show folders in thumbnail view (so I could not operate on folders in the thumbnail view) and I was testing on "favorites" only, not in "folders". I tried to narrow down issues and contexts in order to isolate problems.

1) there is a difference between working in the "folders" tree or the "favorites" tree. All the folder operations (deleting, renaming, creating subfolder) work in "folders" tree (it's not bugless, though see above) and simply don't work in "favorites" tree. From XnView's view, items are deleted/renamed but when you refresh you see that the operation did nothing, deleted/renamed items appear back as they are on the FS.

2) deleting/renaming of files and folders on an external ext3/4 storage simply doesn't work. On an external VFAT system, it works, but deleting will move to trash unconditionally, which is just a minor issue, if it's not GNOME who is handling that by itself (I doubt it, seriously).

3) the context menu contains few operations over "favorites" items, whereas in "folders", it contains much more, why? I understand that a *top-level* folder in "favorites" could be removed from the favorites and not deleted from disk - it should be considered as a virtual entry, but managing subfolders' contents should behave like in "folders" tree. Something is not clear around "favorites" or it's simply not working well.

4) the "favorites" tree subitems never get updated to reflect the FS state, whereas it works in "folders" tree, that seems a bit odd and it's maybe related to 3).

5) when creating a subfolder in a newly created subfolder "new folder 1", the "folders" view will show two subitems with the same name "new folder 1" (only one really exists).

6) In "folders" tree, creating new folders and renaming them lead to random issues like a context menu (upon those newly created folders) with all operations greyed-out. I say "random" because it appeared often but not always during my playtime in folders and I could not yet identify the origin of the issue.

I am reproducing the same issues on two different CentOS6 64-bit systems, with different VFAT and ext3/4 externals disks.

yes you can't delete/rename folder in favorites, only in thumbnail or folder tree

so in thumbnail view?

You can't but the GUI tells you that you can (delete/rename actions are available).

so in thumbnail view?

In thumbnail view, it's the same, you cannot remove from an external ext3/4 storage (the GUI let you think you did, but a refresh shows that you didn't).

and from local storage?

[wwp]

As stated above (maybe not clear enough), "folders" tree or thumbnail view behave the same: on a local storage it's fine.

Pierre, it works .
I had to install Qt5 libs from EPEL repository using yum on my CentOS6 x64 system, and set QT_PLUGIN_PATH to /usr/lib64/qt5/plugins in my environment, et voila.

May I ask if video thumbnails (and preview) work for you?
Pierre mentioned this problem as solved in the changelog,

740: [Bugs] Create thumbnail for video with FFmpeg on Linux/MacOSX

but I had no luck with it so far.

[wwp]

I can't get video thumbnails to show nor videos to play here (CentOS6, XnView MP 0.78 x64). Tested w/ MP4/AVI and MKV files.

Thanks for the info and sorry for being at least slightly offtopic, as this video matter is obviously not only related to older distros.
A pity, that infos about the general requirements for the linux version of MP are rather rare.
With a previous version at least the video preview did work.
I understand very well, that Pierre's main focus is on the core functionality, i.e. handling picture formats.
On the other hand, the video and audio formats are supposed to work under Linux as well , I guess.
Maybe some input from Pierre and/or some linux users more knowledgeable about Linux multimedia-handling (than me)
might be helpful in solving this long standing problem.
For my part I am willing to try or install anything...distros, packages etc.
Best regards

Hi Pierre/ XnView dev guys.

I am a CG supervisor at a small company that specializes in VFX and Game Cinematics, in Warsaw-Poland.
I recently discovered your product XnView which is brilliant. Currently tested many options for ordinary
user on Windows 7 Pro. However, our company due to the high specialization of the whole works mainly on Linux Centos 6.7.
As you may know Centos (RedHut) 6.xx or later is industry standard in our bussines (3d Animation, VFX etc.)
From my 22 years of experience it seems that we and rest of companys do not go too fast on the latest CentOS v. 7.xx
XnView is really 'well polished' software and has a very high potential in our daily work.
We want to fine-tune a few things to implement it into our pipeline and use it in production.

We will definitely be interested in buying at least 15 licenses to start with. But first we have a problem which
is certainly to solve, but it is too expensive in time to 'yourself' to solve this problem. There is a problem
with the launch XnView on the default installation of Centos 6.7. We tried to do as Pierre tells here:
http://newsgroup.xnview.com/viewtopic.php?f=82&t=32584

However, we could not run continues XnView on Centos 6.7. If you can spare some time, please can you posted
a 'step by step' how to install XnView on Centos 6.7? Our standard equipment is workstation with i7 or
Xeon CPU's, lots of RAM, SSD for the system. The system (Centos 6.7) is actually standard. We always installed
drivers for Nvidia graphics card from Nvidia. We use some standard 32bit libraries for some reasons for other
software that we use.

Maybe you can help prepare a package which can simply fireup or unpack and copy to the system?
Maybe some install script with can tell to user what is missing (if is missing) in the system?
The best will be script with just install all requiments for XnView even from the net sites
( maybe even from some repos, etc.).
We count on your help. I'm waiting for some update in this case.

Cheers
Olaf

I use Slackware 14.1 x64 and have installed the QT5 libraries, however when I attempt to start 0.79 it is failing with a message that QT plugin for xcb is missing. I have libxcb version 1.9.1 installed. This happens whether attempting to start from root or user. Any suggestions?
I can get 0.72 to run without the qt5 libraries. Which version of XnView MP started the requirement for qt5?
It would be really nice if there was a list of the minimum libraries required for running each release. Is there a chance you might be able to do that?

Thanks Brian A in MN
