AIX 7.1 TL5 perl -e 'use XML::Parser' error Can't load '.../Expat.so'

  • 1.  AIX 7.1 TL5 perl -e 'use XML::Parser' error Can't load '.../Expat.so'

    Posted Fri March 18, 2022 07:08 AM
    Environment:  AIX7100-05-05-1939
    Problem:
    The command "perl -e 'use XML::Parser'" can run on one server "up2crmsua1" but fails to run on another server "up2f2clua1". I found that the working server has installed the expat RPM packages. So I tried to install both expat RPM packages below on the problem server but it does not help.

      expat-2.4.4-1.ppc
      expat-devel-2.4.4-1.ppc

    up2f2clua1:root:/tmp>lslpp -L |grep -i perl
      perl.libext 2.3.5.31 C F Perl Library Extensions
      perl.rte 5.28.1.0 C F Perl Version 5 Runtime

    -------------------------------------------------------

    The LIBPATH environment variable does not set.  The output of "rpm -qa" and truss when run command is attached.
    Please kindly help to recommend.

    Thanks so much for your help.

    Hi Premvadee,

    This error is because of the latest expat stopped shipping the the library in /usr/lib path.
    As an workaround you may try to run the script as
    LIBPATH=/usr/opt/perl5/lib/5.28.1/aix-thread-multi/CORE:/opt/freeware/lib:/usr/lib perl -e 'use XML::Parser'
    Also, we are trying to avoid perl module dependency on rpm package.
    But this change would be mostly come with latest updated perl version.
