Perl's @INC - am I missing the point?
in [Perl]

From: Andrew Fabbro on 17 Apr 2008 00:02 When building (compiling) perl, I wanted to include a directory where we install our local modules. So I built perl with -Dotherlibdirs=/app/ common/oracle/perl/local. Later, I installed various modules with PREFIX=/app/common/oracle/perl/ local However, perl can't find them (and yes, I checked and /app/common/ oracle/perl/local is in @INC). However, if I put this in @INC: /app/common/oracle/perl/local/lib/site_perl/5.8.8/PA-RISC2.0-LP64 Then it finds things and works just fine. But what the...heck is the point of -Dotherlibdirs if what you point it at doesn't work!? So should I rebuild perl with -Dotherlibdirs set to "/app/common/oracle/perl/local/lib/site_perl/5.8.8/PA-RISC2.0- LP64"? The whole point of this exercise was to avoid having to manually "use lib"... Or perhaps I'm just confused...

I'm sure this makes complete sense to those people who understand this stuff, but I am not one of them. > > However, perl can't find them (and yes, I checked and /app/common/ > oracle/perl/local is in @INC).

You need to use LIB= for MakeMaker rather than PREFIX=. PREFIX is a little weird (for historical reasons); it means 'this is where my whole perl tree is installed', so it will attempt to create a whole lib/ man/ bin/ tree matching the one your perl is installed into, including site_perl and so on.

Also, note that perl will only search arch-specific subdirs of otherlibdirs if they existed when Configure was run. So you need to make sure /app/common/oracle/perl/local/PA-RISC2.0-LP64 exists before you run Configure. Ben
