The @INC array is a list of directories Perl searches when attempting to load modules. To display the current contents of the @INC array:
# perl -e “print join(\”\n\”, @INC);”
The following two methods may be used to append to Perl’s @INC array:
1. Add the directory to the PERL5LIB environment variable.
Centos/Redhat:
# export PERL5LIB=/usr/local/src/api/soap
2. Add use lib ‘directory‘; in your Perl script.
#
## using perl module with direct link to module directory with use lib
# use lib qw (/usr/local/src/api/soap);
#
For more information, read the perlrun manpage or type perldoc lib
