#!/usr/bin/perl -w =head1 NAME dh_autoreconf - Call autoreconf -f -i and keep track of the changed files. =cut use strict; use Debian::Debhelper::Dh_Lib; use Cwd; =head1 SYNOPSIS B<dh_autoreconf> [S<I<debhelper options>>] [B<-X>I<item>] [B<--mode=>I<mode>] [S<I<program> B<--> I<params>>] =head1 DESCRIPTION dh_autoreconf is responsible for calling autoreconf and creating the files debian/autoreconf.before and debian/autoreconf.after which contain checksums of all files before/after the build. It is complemented by dh_autoreconf_clean which creates a list of all changed and added files and removes them. Please note that dh_autoreconf can only be run once. Thus, if you need to run multiple commands, use a script or similar. An example is given in L<dh-autoreconf(7)>. =head1 FILES =over 4 =item debian/autoreconf This file can contain a list of directories. If present, dh_autoreconf will only scan the given directories for changes. If no special command is given to dh_autoreconf, it will also forward the directory list to autoreconf which causes it to be run only on those sub directories. =back =head1 OPTIONS =over 4 =item B<-X>I<item> B<--exclude=>I<item> Exclude files that contain "item" anywhere in their filename from being checked for changes. This means that those files won't be deleted by C<dh_autoreconf_clean> even if there are changes. You may use this option multiple times to build up a list of things to exclude. Starting with version 3, the directories of common version control systems such as cvs, git, hg, svn, and bzr are excluded automatically. =item B<--mode=>I<mode> Change the way in which modifications to files are detected. The default mode is I<md5> for using MD5 checksums, but there is also I<timesize> for using the time of the last modification and the file size. =item B<--as-needed> Enable support for -Wl,--as-needed in all ltmain.sh files identical to the one of the libtool package. This only works in the MD5 mode (the default one). The changes are reverted in dh_autoreconf_clean. You should not prevent LIBTOOLIZE from running with this, as it only works correctly with libtoolize running. =item B<-D>I<dir> B<--sourcedirectory>=I<dir> Run everything in the source directory. Supported only in debhelper compat level 10 for backwards compatibility. =item I<program> B<--> I<params> Run the program given by I<program> with the arguments given by I<params> instead of autoreconf -f -i. If you need to run multiple commands, put them in a script and pass the script instead (or add a target to debian/rules). =back =head1 ENVIRONMENT For each tool executed by L<autoreconf(1)>, one can export a variable with the uppercase name of the tool to the specific program which shall be run, including B<true> to prevent the tool in question from being run. The following example shows the beginning of a debian/rules for a package where automake 1.11 shall be run instead of the default automake version and libtoolize shall not be run: #!/usr/bin/make -f export AUTOMAKE = automake-1.11 export LIBTOOLIZE = true =cut # Check if a configure line matches a certain regular expression sub grep_configure { my $expr = shift; foreach my $configure (("configure.ac", "configure.in")) { return eval { doit("grep", "-q", $expr, $configure) } if (-e $configure); } return 0; } my $opt_sourcedir; init(options => { "mode=s" => \$dh{MODE}, "D=s" => \$opt_sourcedir, "sourcedirectory=s" => \$opt_sourcedir, "as-needed" => \$dh{AS_NEEDED}}); my $exception; my @directories; my $find_options='! -ipath "./debian/*" -a '; my @exclude_default = ("'*/.git/*'", "'*/.hg/*'", "'*/.bzr/*'", "'*/.svn/*'", "'*/CVS/*'"); $find_options .= ("! \\( -path " . join(" -o -path ", @exclude_default) .
