[Buildroot] How to force AUTORECONF for everything

[Buildroot] How to force AUTORECONF for everything

[Sidney Manning]

I've made a change to libtool which requires that I set PACKAGE_AUTORECONF =
YES to many of the library packages.  Rather than changing each package, I'd
like to force this globally.  Is there a way to do that?

Thanks

No, there is no global setting that forces that behaviour.

You'll have to hack the autotools infra. See in package/pkg-autotools.mk at 143:

  139 ifndef $(2)_AUTORECONF
  140  ifdef $(3)_AUTORECONF
  141   $(2)_AUTORECONF = $$($(3)_AUTORECONF)
  142  else
  143   $(2)_AUTORECONF ?= NO
  144  endif
  145 endif

You may want to change that "NO" to a "YES"

But beware, here be dragins...

In theory, there should be no dragons.

In practice, lots and lots of package to not autoreconf properly, so
you're going to face a *lot* of build failures by forcing autoreconf on
all packages.
