  • perl Tk::Zinc

    From Mike Scott@21:1/5 to All on Fri Jan 13 11:42:34 2023

    Hi all.

    I've been trying to resurrect some old code of mine that made use of
    perl's Tk::Zinc code.

    Unfortunately, there seem to have been system changes involving tcl &/or perl/Tk libraries that leave the Tk::Zinc code crashing with a SEGV from
    within Tk's widget creation code, and which I don't have the knowledge
    to fix.

    The code is still listed on CPAN, but CPAN just says to build from
    sources (github), which haven't changed since last used several years
    ago, used to work OK and now don't :-{

    Does anyone out there still use this rather nice piece of software and
    might be able to help please?


    This is on Mint 20.2, perl 5.30, tcl 8.6

    Thanks.

    Did you try and install it with cpan?

    cpan -i Tk::Zinc

    cpan -i Tk::Zinc


    Thanks for the reply.

    Short answer 'no', because the cpan site seemed to suggest building from
    source (and scratching at the back of my mind from several years ago is
    the idea it wasn't on cpan anyway).

    But the cpan install tests fail, so it doesn't complete. I did
    eventually find how to get round the library problem (link a couple of
    stub .a files), but get the same test failure issues. Forcing install
    fails at runtime, unsurprisingly.

    I did notice that there's a cpan testing page that just looks ominously
    red for failure mostly. Looks as though something changed in perl
    several versions ago and zinc hasn't been fixed to match.

    I also see the tkzinc domain is now something else entirely.

    :-{ Good bit of code going to waste it would seem.

    My program uses zinc to provide smooth scrolling of a full-screen image
    across the screen - does anyone know of an alternative possibility please?
