[Buildroot] [PATCH 1/2] host-autoconf-archive: install to a non-standard location

[Romain Naour <romain.naour@openwide.fr>]

Hi Thomas, All,

Le 14/05/2015 22:57, Thomas Petazzoni a ?crit :
> The host-autoconf-archive package was added to provide the necessary
> autoconf macros for the libsigrok package, and later also used for the
> thrift package.
> 
> However, it installs its autoconf macro in
> $(HOST_DIR)/usr/share/aclocal, which is part of the include directory
> of autoconf macros used for all autoreconf invocations. Unfortunately,
> using those macros for all packages is causing a number of
> regressions: one on host-ola fixed in commit
> 884af65fd5ddc548f19a26162f905a32ef0b53b3, and one in snmpp. Those
> packages are autoreconf'ed, but if they are autoreconf'ed with the
> autoconf-archive macros installed, they no longer work.
> 
> To solve this problem, this commit implements a simple solution that
> makes using host-autoconf-archive macros an opt-in mechanism. To
> achieve this, the autoconf-archive package is modified to install its
> macros in a special directory, and only the packages that really want
> to use those macros will have to pass a -I flag pointing to this
> directory in their <pkg>_AUTORECONF_OPTS variable.
