Bug reference: 3978
Logged by: Andy Satori
Email address: dru@druware.com
PostgreSQL version: 8.3
Operating system: Mac OS X
Description: plperl configure / build process behavior wrt Universal
Binaries
Details:
It appears that if you build PG 8.3 on a Mac OS X 10.5 machine setting the
target platform to anything other then the default, the plperl module
incorrectly configures itself to build a universal binary, and, if you are
using an SDK will fail to link due to invalid architecture.
additional details can be provided, but the short version is that so long as
you are building for the deployment hardware and architecture on a matching
system, it's fine, but if you need to cross compile for an alternate
architecture or prior build revision, the current system either builds a
broken plperl or fails to build altogether.
