Thread: vuescan on 13.1

    Default vuescan on 13.1

    I am trying out Vuescan on two boxes. Both are running 13.1 x64.

    The 64 bit version fails on both. It starts but the GUI is not correctly operational. Starting from the command line yields the following error messages:

    On one of the machines the 32 bit version runs correctly but it fails in the same manner on the second.

    Is this an issue with libpng?

    thanks in advance.

    What version of VueScan are you trying?
    I just tried ver 9.4.19 on my 13.1 laptop and see similar issues.
    An older version actually ran, sort of, but flaky.

    Comparing to my 12.3 system where vuescan 9.4.19 runs OK, I see that libz.so is version 1.2.7 for 12.3, 1.2.8 for 13.1

    So, misery loves company, I'm right here with you.

    Since it is proprietary software that is in question, support should be obtained via the vendor (ie their issue).

    Support


    In particular, refer 'How do I submit a Problem Report'

    What version of VueScan are you trying?
    9.4.19

    I contacted the vendor and received a completely useless reply - they simply stated that they test on an old version of Ubunutu and supporting newer versions of Linux is difficult.

    You could to trace the thing, to find out what it loads.

    Maybe you have to try an older version of zlib just for its benefit (library preload option, I think).

    OK, a chance to experiment with some LD debugging.

    I tried the following from the directory where VueScan is unpacked
    Code:
    ~/bin/Vuescan9/VueScan> LD_DEBUG=files ./vuescan 2>debug.out
    ~/bin/Vuescan9/VueScan> cat debug.out |grep fatal
    The problems, symbol look-up errors, start in interfaces to /usr/lib64/gtk-2.0 but there are several others.

    I doubt a simple library substitution will fix this, but I'll keep playing with it

    Default Re: vuescan on 13.1 New information

    Some interesting results to add to this.
    First, I noticed after my last post that the (supposedly) fatal symbol lookup errors reported in my previous post actually appear when the same LD_DEBUG=files ./vuescan test was run on my 12.3 desktop, where vuescan still ran OK. So they are not really fatal.

    After a bit of research, I determined that KDE Skanlite would actually work with my scanner on my desktop, where I do 99% of my scanning. It is not as full featured as vuescan, but I deemed it adequate for my needs and moved ahead to upgrade my desktop to 13.1. When, in error, I selected vuescan rather than skanlite to do a quick scan, I was amused to see vuescan open and run fine on the now 13.1 desktop. So now I am really confused.

    So, with both desktop and laptop now at 13.1, I reran ldd vuescan >file on both machines, edited out the physical load address info and ran
    Code:
    diff desktop2 laptop2
    63c63,64
    <       libatiuki.so.1 => /usr/lib64/libatiuki.so.1 
    ---
    >       libnvidia-tls.so.331.20 => /usr/lib64/tls/libnvidia-tls.so.331.20 
    >       libnvidia-glcore.so.331.20 => /usr/lib64/libnvidia-glcore.so.331.20
    Ah so, I had missed these differences earlier.

    So I now believe it is the video hardware(and drivers) issue. My laptop is a corei7 with integrated intel video and add-on nvidia card. I did install bumblebee and play with it back when 12.3 was loaded, but really do not need it at the moment so have not paid much attention. I am not sure why vuescan sees the laptop as nvidia, not intel.

    I also cannot say for certain that vuescan ran on the laptop prior to seeing the post that started this thread; I don't scan much from the laptop. Perhaps tedbat123 can comment on his experiences here. Being a heavy vuescan user on the desktop, I was very interested in how well it would work with 13.1 before my upgrade.

    When I get to it, I'll bring up bumblebee on my laptop and see if that helps vuescan.

    All this on my laptop:
    In digging about I found that an Nvidia repo was active and that nvidia drivers had been loaded.
    I am not exactly sure how/why.
    This was a "clean" install from dvd.

    I disabled the Nvidia repo then used YAST to remove anything found by search-nvidia that did not want to do other massive package removals.

    After rebooting, intel graphics reported running by Kinfocenter.

    vuescan works fine.

    So vuescan uses something from the nvidia driver if present? What for? :-o
