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

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

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).

    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.

−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.

    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.

    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

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).

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
