Re: libpq.a in a universal binary

Thanks for the reply.... at last nights cocoahead meeting in NYC I
asked and found a solution for libpq.a.

1. config and make on a ppc
2. config and make on intel

copy and rename the libpq.a from each system to a common directory
and run 'lipo' on them:

lipo libpqppc.a libpqintel.a -output libpq.a

lipo will create the universal binary

man lipo:

LIPO
(1)
LIPO(1)

NAME
lipo - create or operate on universal files

SYNOPSIS
lipo [-info] [-detailed_info] [-arch arch_type
input_file] ... [
input_file] ... [-arch_blank arch_type] [-create] [-thin
arch_type]
[-replace arch_type filename] ... [-remove arch_type] ...
[-extract
arch_type] ... [-extract_family arch_type] ... [-output
output_file]
[-segalign arch_type value] ...

DESCRIPTION
The lipo command creates or operates on ``universal'' (multi-
architec-
ture) files. It only ever produces one output file, and
never alters
the input file. The operations that lipo performs are:
listing the
architecture types in a universal file; creating a single
universal
file from one or more input files; thinning out a single
universal file
to one specified architecture type; and extracting,
replacing, and/or
removing architectures types from the input file to create a
single new
universal output file.
