This can be done with perl too: - - perl -i~ -pe "s!c:/djgpp!x:/djroot!i;" lib/perl5/Config.pm - ^^^^^^^^^ - Substitute this with your DJGPP root directory! +=head1 DESCRIPTION - - This version of perl searches its library files in '../lib/perl5/', - which is relative to the path of perl.exe. If you don't like this, - you can use the PERL5LIB environment variable to tell perl where - the library is. E.g: - - set PERL5LIB=c:/perl/lib - - Warning: if you set PERL5LIB and use tainting checks (-T command line - option), perl ignores PERL5LIB, so you must use the -I command line - switch or the "use lib '...'" construct. Or you can patch perl.exe :) +Before you start, you should glance through the README file +found in the top-level directory where the Perl distribution +was extracted.
