Ubuntu Manpage: dh_autoreconf - Call autoreconf -f -i and keep track of the changed files.

NAME

       dh_autoreconf - Call autoreconf -f -i and keep track of the changed files.

SYNOPSIS

       dh_autoreconf [debhelper options] [-Xitem] [--mode=mode] [program -- params]

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 dh-autoreconf(7).

FILES

       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.

OPTIONS

-Xitem --exclude=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 "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.

--mode=mode
Change the way in which modifications to files are detected. The default mode is md5 for using MD5
checksums, but there is also timesize for using the time of the last modification and the file size.

--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.

-Ddir --sourcedirectory=dir
Run everything in the source directory. Supported only in debhelper compat level 10 for backwards
compatibility.

program -- params
Run the program given by program with the arguments given by 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).

ENVIRONMENT

       For each tool executed by autoreconf(1), one can export a variable with the uppercase name of the tool to
       the specific program which shall be run, including 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
