autoreconf phase

[Itaru Kitayama]

Hi,

Am I correct that in autoreconf phase, if a package has configure file, there's

no autoreconf happens at all, but just prints out as every autoconf based package

is supposed to go through the phase?

By default, yes, autoreconf is not run if configure is present, but if you're patching configure.ac / configure.in then you can set the force_autoreconf flag to True as a static variable of your package.py derived class: https://github.com/spack/spack/blob/d805be02eca72de2fd332392db97eda3b8dbd893/lib/spack/spack/build_systems/autotools.py#L78

from spack import *
...
class MySpackPackage(AutotoolsPackage):
    ...
    force_autoreconf = True
    ....

If you have some non-standard m4 macros, you can add them as a build dependency and autoreconf_search_path_args should pick up on those if you add those packages as a dependency and they install their m4 macros under ${prefix}/share/aclocal https://github.com/spack/spack/blob/d805be02eca72de2fd332392db97eda3b8dbd893/lib/spack/spack/build_systems/autotools.py#L284

from spack import *
...
class MySpackPackage(AutotoolsPackage):
    ...
    depends_on('autoconf-archive', type='build') # for various share/aclocal/ax_*.m4
    depends_on('pkgconf', type='build') # for share/aclocal/pkg.m4

    force_autoreconf = True
    ....

In case you need it, pass in any autoreconf flags other than -ivf (like, say, -Werror while you're playing with things) by setting the list autoreconf_extra_args: https://github.com/spack/spack/blob/d805be02eca72de2fd332392db97eda3b8dbd893/lib/spack/spack/build_systems/autotools.py#L80
