NAME

       dh-autoreconf - debhelper add-on to run autoreconf during build

DESCRIPTION

       The dh-autoreconf package provides a sequence addon for debhelper 7 and is enabled by
       default since compatibility level 10. For earlier compatibility levels it can be enabled
       in the following way:

           #!/usr/bin/make -f
           %:
               dh $@ --with autoreconf

       This will call dh_autoreconf prior to dh_auto_configure and will call dh_autoreconf_clean
       before dh_clean.

       For more information on how to control the autoreconf process or how to other possible
       options, read the dh_autoreconf(1) and dh_autoreconf_clean(1) manual pages.

CDBS INTEGRATION

       This package also provides /usr/share/cdbs/1/rules/autoreconf.mk for packages using CDBS.
       The variable "DEB_DH_AUTORECONF_ARGS" can be used to pass extra arguments to
       dh_autoreconf, and the variable "DEB_DH_AUTORECONF_CLEAN_ARGS" to pass arguments to
       dh_autoreconf_clean. See their manual pages for information on available arguments.

TIPS AND EXAMPLES

   PATCHING LTMAIN.SH FOR AS-NEEDED LINKER FLAGS
       You can add support for -Wl,--as-needed to ltmain.sh (at least for those ltmain.sh scripts
       changed during autoreconf) by passing the argument --as-needed to dh_autoreconf, as
       demonstrated in the following example:

           override_dh_autoreconf:
               dh_autoreconf --as-needed

       and for CDBS, by adding it to the correct variable such as:

           DEB_DH_AUTORECONF_ARGS = --as-needed

       For more information about this feature, see dh_autoreconf(1)

   RUNNING MULTIPLE COMMANDS WITH DH_AUTORECONF
       Please note that you may run dh_autoreconf only once. If you need to run multiple
       commands, you can put the commands into a script or your debian/rules file and then pass
       the name of your script to dh_autoreconf. For example, if your script is called
       debian/autogen.sh, you can put the following into your debian/rules if you use dh:

           override_dh_autoreconf:
               dh_autoreconf debian/autogen.sh

       Or, if you use CDBS:

           DEB_DH_AUTORECONF_ARGS += debian/autogen.sh

CAVEATS

       dh_autoreconf is mostly a superset of the dh_update_autotools_config debhelper command
       included in debhelper since version 9.20160115. When using the dh sequencer,
       dh_update_autotools_config is run before dh_autoreconf and updates the config.guess and
       config.sub files. This is required in cases where autoreconf does not update config.guess
       and config.sub itself.

       From time to time, there might be a short breakage for those using automatic ltmain.sh
       patching, when the patch no longer applies to the ltmain.sh.

       You can only run dh_autoreconf once. Future versions may be able to be run multiple times,
       but this requires slightly more planning.
