[FILE]... - -Example: - - depmod.pl -F linux/System.map target/lib/modules - -=head1 DESCRIPTION - -The purpose of this script is to automagically generate a list of of kernel -module dependancies. This script produces dependancy lists that should be -identical to the depmod program from the modutils package. Unlike the depmod -binary, however, depmod.pl is designed to be run on your host system, not -on your target system. - -This script was written by David Schleef to be used in -conjunction with the BusyBox modprobe applet. - -=head1 OPTIONS - -=over 4 - -=item B<-h --help> - -This displays the help message. - -=item B<-b --basedir> - -The base directory uner which the target's modules will be found. This -defaults to the /lib/modules directory. - -=item B<-k --kernel> - -Kernel binary for the target. You must either supply a kernel binary -or a kernel symbol file (using the -F option). - -=item B<-F --kernelsyms> - -Kernel symbol file for the target. You must supply either a kernel symbol file -kernel binary for the target (using the -k option). - -=item B<-n --stdout> - -Write to stdout instead of modules.dep. This is currently hard coded... -kernel binary for the target (using the -k option). - -=item B<--verbose> - -Be verbose (not implemented) - -=back - -=head1 COPYRIGHT - -Copyright (c) 2001 David Schleef -Copyright (c) 2001 Erik Andersen -Copyright (c) 2001 Stuart Hughes -This program is free software; you can redistribute it and/or modify it -under the same terms as Perl itself. - -=head1 AUTHOR - -David Schleef - -=cut - -# $Id: depmod.pl,v 1.1.1.4 2003/10/14 08:09:40 sparq Exp $ - -- cgit v1.2.3-54-g00ecf
