Thread: Unresolved references on 11.23 (Itanium)

  1. Unresolved references on 11.23 (Itanium)

    Hello,

    We have been using python and its cx_oracle extension on
    PA-Risc (HPUX 11.11) without problems.
    Unfortunately, I am hitting unresolved references when trying
    to compile the same OSS on 11.23 (Itanium ia64). This happens
    with gcc as well as with the HP ansi compiler; in 32 or 64
    bits data model.

    I have already posted to one oracle NG and the cx_oracle support
    list, to no avail so far. I'll include links to posts with all the
    details at the end of this message, but I _think_ it boils down to
    one Oracle lib (libnnz10.so) not being able to resolve a whole lot
    of symbols. Here are a few examples:

    /usr/lib/hpux64/dld.so: Unsatisfied data symbol 'nltrc_entry'
    Unsatisfied code symbol'SSL_PROTOCOL_TLSV1_SSLV3_V2_SERVERSIDE'
    Unsatisfied code symbol 'ldap_unbind_s'
    Unsatisfied code symbol 'ssl_Handshake'
    ....etc...ad nauseam...

    This seems to suggest one network (dynamic?) lib cannot be located.
    Would anyone recognise these symbols and happen to know which
    library provides those routines?

    Thanks for any suggestion,

    Bernard.

    One quick check might be to run chatr/ldd against the PA-RISC
    binary(ies) you are using - chances are decent the libraries would be
    of the same names under Itanium.

    Since SSL appears in several of the symbols, is an HP OpenSSL
    installed on the PA_RISC system, but not the IPF?

    Was there a configure script run, and perhaps does its log show
    anything amis?

    Not that I know, or that immediately appears from ldd's output
    (see below)

    > Was there a configure script run, and perhaps does its log show

    There is a configure script for python, and cx_oracle uses
    the python distutils mechanism. Both of these seem to work,
    and don't complain or reveal anything remarkable (to me).
    The python interpreter definitely works, and its oracle extension
    gets (dynamically) linked, but the problems occur when trying
    to load the extension module from the interpreter (or a script).

    Alright, since you asked ;-) I can't say anything strikes me that
    would be present on the older system only, but you be the judge.
