Thread: plperl again but different problem
Hello.. I've installed plperl.so in postgresql lib directory but when I try to create lang, such error occures: pgsql2-test:~# su pgadmin pgadmin@pgsql2-test:/root$ /usr/local/postgresql/bin/createlang -p 5433 plperlu pl createlang: language installation failed: ERROR: could not load library "/usr/local/postgresql-8.0.3/lib/plperl.so": /usr/local/postgresql-8.0.3/lib/plperl.so: undefined symbol: Perl_croak pgadmin@pgsql2-test:/root$ I've even compiled perl from sources but still have this error. What's going on? Thx, Marcin

I think you've got some kind of mismatch between the compilation options
for Perl proper and those for plperl. IIRC, Perl can spell its exported
function names in several different ways (eg, with or without the Perl_
prefix). It looks like plperl is expecting a different convention than
what the libperl.so file was actually built with.
Use ldd on plperl.so to double check which libperl it's trying to link
to. Double check that the Perl header files you compiled plperl against
came from the same Perl build that produced libperl.so.

I don't see any libperl.so :( But doesn't plperl use shared libperl library?
"....libperl must have been built as a shared library, which is usually not
the case in standard installations..." taken from README file
I've changed configure script and put PERL variable as
PERL=/usr/local/perl/bin/perl - so all things related to perl where taken
from this place.

How big a plperl.so do you have? Mine's about 160K (in a debug-enabled
build), whereas libperl.so is about 1.3M on this machine. If your
plperl.so is over a megabyte then libperl might be statically linked
into it.

Hi again My PostgreSQL (built from sources) is running on Sarge too, bit I didn't have any such a problems. What's more, I have both Perls installed in standard places. Try to run 'locate *libperl*' to check if there isn't more then one on your system. Sergiusz

For PostgreSQL compiled from sources, it's statically linked:
postgres@ns02:/usr/local/pgsql/lib$ ldd plpgsql.so
libc.so.6 => /lib/tls/libc.so.6 (0xb7ea5000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

Well, it's not statically linked then. You should go back into
src/pl/plperl and do "make clean all" so you can see what command was
done to produce plperl.so.

OK ... I have compiled it once again - really don't know why this time
libperl is visible?:
pgsql2-test:/usr/src/postgresql-8.0.3/src/pl/plperl#
pgsql2-test:/usr/src/postgresql-8.0.3/src/pl/plperl# ldd libplperl.so
libperl.so => /usr/lib/libperl.so (0xb7ed1000)
libdl.so.2 => /lib/tls/libdl.so.2 (0xb7ecd000)
libm.so.6 => /lib/tls/libm.so.6 (0xb7eab000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0xb7e9c000)
libc.so.6 => /lib/tls/libc.so.6 (0xb7d67000)
libcrypt.so.1 => /lib/tls/libcrypt.so.1 (0xb7d3a000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
pgsql2-test:/usr/src/postgresql-8.0.3/src/pl/plperl#
But still problem with Perl_craok exists during creating lang plperl ;(

Sounds like you did it wrong the first time ;-)

This is linking to a system copy of libperl. I thought you said you
were building against a private copy? Maybe you forgot to alter the
ldconfig search path to find the private copy first.

Ok guys... thanks you both ;) I've installed perl once again into default location and now IT'S ALIVE !!!!! Thanks once again. Marcin

That's the setup I have and it seems to work flawlessly.
