I used the statement use DBI in the perl prg. This perl was automatically loaded when Redhat5.2 was installed. The prog statement #!/usr/local/bin/perl use DBI; exit; #End of testing module Interpreter tells that can't locate DBI.pm in @INC (@INC contains: /usr/lib/perl5/i386-linux/5.00404 /usr/lib/perl5 /usr/lib/perl5/site_perl/i385-linux /usr/lib/perl5/site_perl At test.pl As I use Pgsql as the backend I installed perl-PgSQL-0_51-1_i386.rpm(downloaded from rpmfind.net) It provided the required files in the paths mentioned. Still it says the same error.(In the command prompt). But one file named as test1.pl automatically while installing ther above rpm file. #perl test1.pl says that Unable to locate unix.pm.and same as the above error. downloaded perl-5_004m7-1_i386.rpm(from rpmfind.net) Tried to install.It says that Unable to install. Can u help me please?I'm in urgency. thanks, Revathi. ____________________________________________________________________ Get free email and a permanent address at http://www.netaddress.com/?N=1
