  • 1.  AIX 7.2 DNF Dependency Issue

    Posted Fri February 17, 2023 05:17 PM

    Hi Team, I need assistance getting dnf up & running. I have downloaded and installed the latest dnf_aixtoolbox.sh script and installed it successfully. Executing dnf results in the following:

    AIXADVNYC10>root>/tmp/rpms>>dnf list
    exec(): 0509-036 Cannot load program /opt/freeware/bin/python3_32 because of the following errors:
    rtld: 0712-001 Symbol _GLOBAL__AIXI_libexpat_so was referenced
          from module python3_32(), but a runtime definition
          of the symbol was not found.
    rtld: 0712-001 Symbol _GLOBAL__AIXD_libexpat_so was referenced
          from module python3_32(), but a runtime definition
          of the symbol was not found.
    AIXADVNYC10>root>/tmp/rpms>>

    My main goal is to be able to install and/or update libstdc and libgcc packages (for a customer) while avoiding dependency issues. I've spent several days reading articles regarding this issue and similar issues and have to admit that all my efforts to resolve this have failed thus far. I am not really clear if this is package issue, PATH issue or python issue. I will post some details below. I am suspecting that either the expat package needs to get updated or python may not be properly linked.  I have tried with LIBPATH set and unset.  I understand that my AIX machine may contain a mix of AIX Toolbox and non-toolbox packages.  I have updated to the latest rpm-rte fileset (rpm.rte.4.15.1.1006).  I did inherit this machine from another team.  Any advice is greatly appreciated.  I'm happy to provide any more details needed.

    Hi,

    Not an expert here and never tried to do that, but issues that could be worth investigating...

    The error seems to be from trying to execute python 3 32bit. 
    "Cannot load program /opt/freeware/bin/python3_32"
    Firstly I'd really want to use python 64 bit which does appear to be installed.

    But more significantly, it looks like /usr/bin/python is linked to python 2
      lrwxrwxrwx    1 root     system            7 Apr 11 2022  /opt/freeware/bin/python -> python2

    You might try fixing that and pointing it at where ever python3.7m_32 is installed (or better python3.7m_64 if that will work)

    Executing python -V should tell you when you have that sorted.  Not saying that is going to resolve your problem but it's a good start.  Make sure you record all your changes so you can back them out if needed.

    Good luck.

    Looks like the expat rpm installed in the machine may not be from Toolbox. Can you share the below outputs ?
    rpm -qi expat 
    dump -Tov /opt/freeware/lib/libexpat.a | grep AIX

    Also we have a separate forum to discuss Opensource issues in AIX --> https://community.ibm.com/community/user/power/communities/community-home?CommunityKey=10c1d831-47ee-4d92-a138-b03f7896f7c9

    Thanks for the reply.  Here is the requested output.  And let me know if I should repost this issue at the Opensource link you provided.

    Summary     : An XML parser library
    Description :
    This is expat, the C library for parsing XML, written by James Clark. Expat
    is a stream oriented XML parser. This means that you register handlers with
    the parser prior to starting the parse. These handlers are called when the
    parser discovers the associated structures in the document being parsed. A
    start tag is an example of the kind of structures for which you may
    register handlers.

    The library is available as 32-bit and 64-bit.

    expat 2.2.4 is pretty old and built using xlc, So it won't have those reported missing symbols. 
    Please install the recent expat version 2.5.0 from Toolbox and try again.
