  • Error finding libXm.so.4

    From Doug Laidlaw@2:250/1 to All on Wed Oct 9 18:09:04 2019
    [I think that something like this happened once before, a library was
    there, but "invisible."]

    I am running Xephem, an astronomy program written in Motif. It has
    libXm.so.4 as a dependency. libXm.so.4 is in /usr/lib, as a symlink to libXm.so.4.0.4, but Xephem can't find it. I tried to uninstall and
    reinstall the library, but that would have removed a swag of apps,
    including Cups and Xephem itself. It worked in the past day or so. I
    ran "sudo ldconfig" as a precaution, but that may no longer be relevant
    in the systemd world. Rebooting had no effect.

    Is there a reason why this happens?

    Two immediate silly things come to mind.
    Is it permissions or is /usr/lib in the $PATH.

    Naturally, I checked both those. My next thought is that libXm.so.4.0.4
    won't work in this program (the reason why I have always advocated using
    only Mageia RPMs.) I am running Cauldron, for other reasons. 7.1
    Official doesn't have the problem. That suggested that maybe there was a recent update of the library, but the Changelog shows that there wasn't
    one. I could try recompiling xephem from the tarball.

    Can you please give me the sig line that pulls in this info? BitTwister
    gave it to me long ago, but I have lost it.

    That is not a line. it is a few lines in a script usually executed
    during login.

    Bits has considerable elaborated the sig line command these days but I
    still use the original dropped into ".bash_profile"

    You can also run it with "strace". If, unlike me, you can follow the
    output and see if it finds the library.
