You may wish to look at "BEGIN" ... Hope that gives you some ideas...
Thanks, jwm -----Original Message----- From: Thompson, Glenn [mailto:[EMAIL PROTECTED] Sent: Thursday, July 29, 2004 10:54 AM To: [EMAIL PROTECTED] Subject: use lib - not known at compile time I'm trying to add my own module "DEGS::ldegs" to a Perl program. However, this module will part of a distribution called "RGSE", which could be installed on a different path on different peoples PCs. However, it will always be in the directory "$ENV{RGSE}/lib". The problem is when I run the program I get an error like: "Empty compile time value given to use lib at /home/gtho/Rgse/bin/depsol-gmt line 44" This presumably is because "use lib" cannot be used on a variable that is undefined at compile time. Now I know I can run the program in the following way: perl -I$ENV{RGSE}/lib myprogram.pl which could easily be put in a wrapper shell script. But is there anyway of avoiding this, and have "use lib" work on $ENV{RGSE} "dynamically"? Hopefully I'm missing something really simple here! Here is a snippet from the program: use lib "$ENV{RGSE}/lib"; # directory when DEGS::ldegs is contained # Read necessary Perl libraries use DEGS::ldegs qw(&wait_for_enter &run &pythag &minmax &get_obj &get_y_limits &page_get_size &set_tick_interval &add_legend &get_lim2 &page_setup_gm &add_fold_points); Thanks, Cheetah ********************************************************************* This e-mail message, and any files transmitted with it, are confidential and intended solely for the use of the addressee.
