    python-mysqldb__debian_to_freebsd


    Greetings ....

    I'm using a commercial web host running FreeBSD
    that fortunately has Python and MySQL,
    but no python-mysqldb module ....

    Before begging the host to install it
    I thought I would try the Debian version
    that I have on the outside chance
    that it might fly directly under FreeBSD
    on the server ....

    import MySQLdb .... leads to the ImportError message ....

    Shared object "libpthread.so. 0" not found,
    required by "_mysql.so"

    On my local Debian installation the reference
    to that particular library file is actually
    a symbolic link ....

    libpthread.so.0 -> libpthread-0.10.so

    I copied libpthread-0.10.so over to the server
    in a directory that is in the Python search path
    and renamed it to libpthread.so.0 ....

    I tried to make the symbolic link as above
    from Python since I don't have a shell account,
    but it failed for some reason that I don't recall
    at the moment ....

    After a bit of google-izing and a quick scan
    of the MySQL install docs, I also set
    the LD_LIBRARY_PATH enviroment variable
    to point to the dir where the supposed missing
    file lives ....

    Is there any at all chance that this will work
    with the proper configs or should I go ahead
    and beg the host for an installation ?

    Any clues would be greatly appreciated ....

    It seems to me very unlikely that a program compiled for FreeBSD would link
    to a library compiled for Debian Linux which in turn was linked to a Debian
    libmysql but now has to work with the FreeBSD libmysql... I just don't
    beleive you can make this work.

        Arrgh. Damjan, you *really* should have left enough context for those
        reading what you have to say to figure out what that "this" was. I
        have as yet to see the original on my news server, so I chased it down
        on Google groups.

        For the interested, the OP (Stanley Kitching), wants to use a
        python-mysqldb module on his web host running FreeBSD. They don't have
        the that installed, so he tried getting the Debian binary distrubtion
        of the library to work, and failed. He's wondering if this is at all
        possible.

        Answer: yes, it might (key word - might) be made to work. Linux shared
        libraries have been made to work with native applications on FreeBSD
        before. I don't have the details, but would expect you'd have to
        install large chunks of a Debian system to make this work. If you
        really want to do this, let me know and I'll chase the details down
        for you.

        However, that's the wrong way to do this. First step - ask your
        hosting service to install databases/py-MySQLdb. That's the Python
        MySQLdb port in the FreeBSD ports tree. Installing it should be
        trivial. If they won't, I'd seriously consider changing services. I
        can recommend a FreeBSD-based hosting service that will install pretty
        much anything in the ports tree.

        The next thing to try is getting the MySQLdb pkg for FreeBSD. A pkg is
        the format that FreeBSD uses for binary distributions. Look in
        ftp://ftp.freebsd.org/pub/FreeBSD/ports/<ARCH>/packages-<REL>/databases.
        Supported architectures are alpha, amd64, i386, ia64 and
        sparc64. Supported releases (for i386, anyway) include the last
        release version of FreeBSD 4, 5 and 6, the stable branch of 4 and 6,
        the development and stable branches of 5, and 7-current. Most of those
        should be for Python 2.4. The one I checked had MySQLdb 1.2.0 and
        1.2.1c3 (a development branch).

        If that fails (because they don't have a binary for the right
        combination of OS and Python), get the version of the os (use the
        command "uname -pr") and the version of Python, and ask here and on
        questions@freeb sd.org to see if someone with an appropriate
        installation will build you a binary. I'll do it if I have the
        appropriate version of FreeBSD installed. Or install FreeBSD on a
        spare system and build it yourself - once you get FreeBSD installed,
        the rest is trivial, and I'll be glad to provide pointers for that.

        If all that fails, *then* it's time to look into getting the debian
        version of the library to work.

            Mike ....

            Although I've never done it personally, I have seen a few
            newsgroup references that some Debian/FreeBSD packages
            are interchangeable so thought the minimal effort required
            for uploading the Debian MySQLdb package I have might be worth
            the long shot ....

            I did a bit more google-izing last night and found
            that a FreeBSD/MySQLdb install should indeed be
            a trivial matter to install via FreePorts ....

            Both are greatly appreciated ....
