I am playing with MySql and Perl. The book I am using is Perl Database Programming. Not a bad book, btw. My problem is this: The book also uses Tk. When I run the program I get the following error message: ======================================================================== ./listing5-4.pl Can't locate Tk.pm in @INC (@INC contains: /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 .) at ./listing5-4.pl line 10. BEGIN failed--compilation aborted at ./listing5-4.pl line 10. ========================================================================= The program uses the statement "use Tk;" which is line 10. From the error messages I would guess that I need the Tk.pm module. I am running RH9, I installed Tk/tcl, Tkinter after I installed the system. I looked on Cpan and got almost 800 modules when searching for Tk::pm in the modules section, but did not find Tk::pm lidted. Anyone know off hand where I can find this module, and if I actually need it. TIA FrankM
