Would it be possible to add a path spec to the --with-perl configure option so that if we have 2 or more PERL versions on the system we can pick which one to use?

We used to have a configure switch, but it is not there anymore. The way I do it is to add PERL=perl5 in /pgsql/src/Makefile.custom. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Why do you need that, as opposed to just setting your PATH so that
configure finds the right one first?

I may be testing a new version of PERL and want PG to compile against that one as WELL as the system default.

On BSD/OS, there is perl (perl4) and perl5 (perl5). You have to set the name of the perl executable. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

The standard interface to any Autoconf configure script to override the name of a program has always been and will always be setting environment variables like this: PERL=perl3 CC=cc YACC='bison -y' TCLSH=/usr/local/bin/tclsh AWK=mawk ./configure --options ... (Okay, I lied, in Autoconf 2.50-to-be you can also put the variable assignments after the "./configure", but that doesn't change the overall principle.) The idea here is that you might set some of these environment variables permanently on your system and then every configure script you run will use the same defaults. -- Peter Eisentraut peter_e@gmx.net http://yi.org/peter-e/

The trick here is that the software not call perl directly, but use the PREL environment variable if defined. I wish all software followed that practice like we do. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026

Oh, so it wouldn't be a search path but a specific executable name
(with or without full path info). OK, that makes sense to me.
I've had different perls installed with different executable names
myself.
