Your Expat.so depends on external libraries (libexpat.so). Do an

to see what libraries your version is dependent upon. You then either need to update your LD_LIBRARY_PATH to include the libexpat.so directory (or update whatever conf file Solaris uses to control library loading - on linux it's /etc/ld.so.conf).

derby,

I appreciate your help. I think I've done what you've suggested.

ldd /home/reliant/shaw/perlmodules/sun4-solaris/auto/XML/Parser/Expat/
+Expat.so
        libexpat.so.1 =>         /home/reliant/shaw/.local/lib/libexpa
+t.so.1
        libc.so.1 =>             /usr/lib/libc.so.1
        libgcc_s.so.1 =>         /local/gnu/lib//libgcc_s.so.1
        libdl.so.1 =>            /usr/lib/libdl.so.1
        /usr/platform/SUNW,Ultra-80/lib/libc_psr.so.1

So I modified my script to add /local/gnu/lib, /home/reliant/shaw/.local/lib, /usr/lib and /usr/platform/SUNW,Ultra-80/lib to the LD_LIBRARY_PATH environment variable. The new script reads:

#!/usr/bin/perl
use strict;
use warnings;
use CGI qw/:standard/;

print header;
use CGI::Carp qw(fatalsToBrowser);

print `LD_LIBRARY_PATH="/local/gnu/lib/:/local/lib/:\$LD_LIBRARY_PATH"
+`;
print `EXPORT LD_LIBRARY_PATH`;

use lib ('/home/reliant/shaw/perlmodules');
use lib ('/home/reliant/shaw/perlmodules/sun4-solaris');
print "<pre>";
use Data::Dumper;
print Dumper \%ENV;
$ENV{'LD_LIBRARY_PATH'} .= ':/local/gnu/lib:/home/reliant/shaw/.local/
+lib:/usr/lib:/usr/platform/SUNW,Ultra-80/lib';

print `env`;
require XML::Simple;
require XML::Parser;

It's output is:

It looks like the environment variable LD_LIBRARY_PATH is being updated with the new directories, but it's not having any impact.

Anyone else have any suggestions?

Cheers,

Brent


-- Yeah, I'm a Delt.

print `LD_LIBRARY_PATH="/local/gnu/lib/:/local/lib/:\$LD_LIBRARY_PATH"
+`;
print `EXPORT LD_LIBRARY_PATH`;
[download]

That's not going to work. That will set the environment var in your subshell but when you return from the backtick call the variable will be gone. See programatically setting the LD_LIBRARY_PATH (especially the comment from tye)

-derby

Do ldd from CGI then compare

./configure --enable-static --disable-shared --prefix=/home/reliant/sh
+aw/.local
[download]

Weirdly enough, the --enable-static trick did not work out for me, but for completeness (and off-site backup :) ), here is what I need to do to build expat and XML::Parser on Solaris x86 with the SUN C compiler:

First build expat:

PATH=/usr/ccs/bin:$PATH     # to add the correct "ar"

# autotools does not seem to know when the configuration was changed, 
+this is just a safety measure
gmake clean 

CC=/opt/SUNWspro/bin/cc CFLAGS="-KPIC -O -D_LARGEFILE_SOURCE -D_FILE_O
+FFSET_BITS=64 -DPERL_USE_SAFE_PUTENV -xarch=generic64" ./configure  -
+-prefix=/home/corion/lib --enable-shared

gmake all

# this one might not compile the C++ checks, if you don't have the SUN
+ C++ compiler installed
gmake check 

gmake install
[download]

After installation, remember to update LD_LIBRARY_PATH in an appropriate location:

# Update LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/corion/lib
[download]

Then, the installation of XML::Parser works, although the SUN C compiler did not like having the library directories listed after the -lexpat command. So I had to fudge that by patching the Makefile.PL:

unless (
  check_lib(     # fill in what you prompted the user for here
    #lib => [qw(expat)],
    header => ['expat.h'],
    debug => 1,
    incpath => $expat_incpath,
    # Ugly hack here
    ($expat_libpath?
    (libpath => "$expat_libpath -lexpat"):()),
  )) {
[download]

Then, configuring and testing Just Works:

perl Makefile.PL EXPATLIBPATH=/home/corion/lib/lib EXPATINCPATH=/home/
+corion/lib/include -lexpat
gmake
gmake test
gmake install
[download]

It's year 2025 and still this post is a life saver
This is still working as perfect fix for building XML::Parser from source (x64 Edition) on Windows Server 2019 as well as Windows 10 and above using MSVC 2022 Community Edition

Then I reinstalled XML::Parser as before, and it worked. At that point, I replaced the (linked) Expat.so file on the production server with the (static) Expat.so file from the development server I was working on.

A special thanks to Derby for pointing me in the right direction with ldd and LD_LIBRARY_PATH. He was correct about my LD_LIBRARY_PATH being out of whack. I'm sure the suggestions to fix my LD_LIBRARY_PATH would have worked, but it was easier for me to replace the Expat.so with a staticly compiled copy.

Cheers,

Brent
