Thread: Unbreak plperl building
This patch, when applied in src/pl will unbreak plperl in
7.0.2 release. Sorry, if that's fixed ages ago - I don't track
development versions of PostgreSQL.
Patch is just a little bit tested (some valid functions created and
successfully run as well as some erroneous ones created and emitted proper
error messages when used).
My platform is FreeBSD 5.0-CURRENT (with perl 5.6.0 provided in the
base system).
I'm not subscribed to any of pgsql lists, sorry. Cc: please.

The issue isn't so much that it's "broken" as that we've seen severe
portability problems with it --- it doesn't work on all platforms or
all releases of Perl. What do your proposed changes do for or against
that issue?

Those come with older (and currently much more used) perl 5.005. No Linuxen of whatever else, sorry. These changes work around some nasty compile-time errors. The author either had a very weird distribution of perl (home-made?) or maybe just didn't have time to finish work (which is strange as one can see from "complexity" of my patch). Anyway, there aren't so many releases of perl available, really. 5.005 and 5.6.0 are surely the only ones to care about. I just loved the idea of writing functions in Perl, and it works for me now. Someone is likely to want it too, so I posted. Thanks for the wonderful PostreeSQL, folks! -- Alex Kapranoff, Voice: +7(0832)791845. 125 days till brand new millenium...
I have applied this and re-enabled plperl compilation. Thanks.

Still doesn't work here. I have Redhat 5.2, fairly average. Please disable
it.
