Makefile messing up @INC

jacques has asked for the wisdom of the Perl Monks concerning the following question:

I have 21 directories in my @INC. But when I build my Makefile with Makefile.PL and run 'make test', I suddenly have 182 entries in my @INC (when using 'make' to run the test script).

The vast majority of those directories do not exist. So I realized that something must be wrong in my Makefile, but I don't know what. Perhaps something is wrong with the values derived from config.sh, which the Makefile draws upon?

Any ideas are appreciated. Here is some of my Makefile:

# --- MakeMaker const_config section:

# These definitions are from config.sh (via /usr/lib/perl5/5.8.3/i386-
+linux-thread-multi/Config.pm)

Any -I on the command line gets added to @INC, as will any subdirectories that also match the architecture. Why do you care if there are many entries in @INC? -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.	[reply]
Re^2: Makefile messing up @INC by jacques (Priest) on Jul 26, 2005 at 22:58 UTC
It's messing up my test script. My script uses values from @INC. There should only be 21 entries, but when the script is run (with make test) there are 182. So I am getting a load of errors. When I run the test script without make, I get the correct 21 entries.	[reply]

That sounds like a really fragile test. As long as whoever uses your code has the correct `@INC` for the machine and environment, why does your code care how it works?	[reply] [d/l]
