Hi,
I have an installation of Postgres 7.4.2 on SuSE 9.1. This version
of SuSE comes with a binary for plperl and several other postgres
procedural languages. All the others, including plpgsql install without
a problem, but executing:
createlang -u postgres plperl template1
produces the result:
createlang: language installation failed: ERROR: could not load library
"/usr/lib/postgresql/plperl.so": libperl.so: cannot open shared object
file: No such file or directory
The file, however, is there:
# ls -l /usr/lib/postgresql/plperl.so
-rwxr-xr-x 1 root root 37097 Apr 5 2004 /usr/lib/postgresql/plperl.so
Some googling gave me the idea that it may be a problem with the way
perl was compiled - i.e, perl is not compiled for shared libraries. Can
anyone confirm this? If so, do I need to rebuild perl, or pl/perl, or
both? Are there any binaries that can resolve this? (yes not wanting
to compile plperl is plain old laziness, but I do have reservations
about recompiling the perl interpreter)
Any ideas would be helpful.
Thanks,
Eric

The error message gives you the hint you need. The missing file isn't
plperl.so - it's libperl.so.
libperl.so is the dynamic library version of perl. It's not usually
installed by most people building perl. (It's also not neccesarily
needed by plperl.so, as libperl.a can be statically linked into
plperl.so, I believe).
I don't know SuSEs package system (I always install from source) but
there may well be another perl package that would provide libperl.so.
Failing that you'll either need to build a perl installation and tell
Configure to build libperl.so, or rebuild plperl.so. It's also
possible that you do have libperl.so somewhere, but it's not on
the standard library search path and not where plperl expects
to find it.
'ldd' is a useful command for tracking down this sort of problem.
Cheers,
Steve

It's complaining that it can't find libperl.so (ie, the Perl interpreter)
not plperl.so. Do you have a libperl.so? Is it in your ldconfig search
path?

Hi Steve and Tom,
Thanks for the tip, I was clearly not reading the error message closely
enough.
I copied libperl.so into /lib, and now everything works.
Many thanks,
Eric

I realize this is the php group, but I have a question that recurses
back to my php install.
My objective is a pure 64 bit shared object installation of php 5.0 on
UltraSparc Solaris 9 compiled with the Sun Compiler version 8.
My problem is that EVERYTHING builds great EXCEPT that the 6b
distribution of JPEG will NOT build a shared object, thus gd cannot
include support for JPEG, thus php loses that functionality.

Before I go deep into this - does anyone have the quick fix for this ?
Some facts - the 7.3.4 version of plperl.c has the same errors in the
7.4 tree.
The 7.4 version of plperl.c (with some error handling API calls
commented out) compiles fine in the 7.3.4 tree.
(Same machine - same install of perl !) Points to using some alternate
perl API probably by macro collision ?

Hi,
I am facing a weird issue:
We are using a shared library (libcarob) that can throw exceptions.
Everything goes well under most platforms, but under suse (SLES 9, gcc
3.3.3), we get a segfault anytime we try to throw an exception out of
carob.
The weird thing is that when linking statically carob to the libstdc++,
the problem disappears. Google showed nothing convincing, so I try

I've occasionally had trouble compiling and linking programs that use shared
libraries. That never made a lot of sense to me, because I thought the
operating system went hunting for the symbols and libraries at runtime (and
not before).
Questions:
a)How do the development tools know that a given symbol (a function entry
point, for example) is located in a shared library and won't be linked in
statically?
