    Are pdfseparate error messages documented?
    If so, where?

    Have you tested poppler with trixie, because bookworm's is now
    three major versions behind.

    [Hopefully, this post won't languish at relay.mailchannels.net
    for four hours, unlike this morning's.]

    Cheers,
    David.

    Bookworm(Debian 12) is the current *major* version.
    [I'm running Debian 12.8 which is behind by three *point* releases.]

    Trixie(Debian 13) will be the next major version.
    It is still in testing and not yet in full freeze. [https://lists.debian.org/debian-devel-announce/2025/07/msg00003.html]

    I won't install Trixie until a week or two after its full release.
    I would normally wait for a point release or two, but I had problem
    attempting to install pdftk. It is unclear if it was release level
    related a local hardware/software issue.

    I don't know about the "if", but the "where" would be < https://poppler.freedesktop.org/>.

    Not a particularly useful page except for the link to their mailing list.

    Bookworm(Debian 12) is the current *major* version.

    Software in a stable distribution like Debian does not get updated
    during the life of the Debian release. That means that the version of
    Poppler (or anything else, with some rare exceptions) that is in Debian
    on the day of the bookworm release is the version that is always in
    bookworm for years to come.

    I think David is suggesting that Poppler in Debian 12 is now three major versions *of Poppler* behind.

    Thanks,
    Andy

    That makes sense, especially after looking at the subject lines of the
    last six months of the Poppler mailing list.

    After the dust settles from Trixie's pending release I should be able to install current version of pdftk and the Poppler packages.


    Thanks,
    Andy

    How/where do I find interpretation of those?

    I'm still interested in the meaning of the error messages as it may
    hint as why ""pdftotext" wasn't *exactly* what I hoped for.

    They are documented as poppler source code. Likely you should be
    familiar with PDF format specification to judge it if is failure of
    poppler or of those who created the file.


    I'm evidently not as aware of implications of PDF's graphical
    orientation even when dealing with text as I might wish.

    See David's message for a reason why it may be better to avoid
    pdfseparate. (It may still have its niche.)

    Noting the difference in reported file sizes of output of pdfseparate
    and pdftk, the later may be more appropriate for some of my future goals.

    Max Nikulin (HE12025-07-26):
    You may have testing or unstable as a virtual machine. Of course, it means using a search engine rather actively and perhaps some failures before you will manage to setup it.

    Why a VM? A chroot is quite enough to run a simple program from another
    Linux, with only the cost of loading other versions of shared libraries,
    saving the cost for the kernel and supporting daemons in the VM.

    It is also more convenient to interact with the files on the host
    system. And it is very easy to set up with Debian using debootstrap.

    Unpacking the packages in /usr/local and playing with symlinks and LD_LIBRARY_PATH is an even more convenient solution than a chroot, but
    it requires more know-how.
