From 9687e7435b76707afcf8b9aef15c98ea5287da75 Mon Sep 17 00:00:00 2001 From: Erico Nunes Date: Tue, 25 Oct 2016 23:21:09 +0200 Subject: [PATCH] perl: update cnf/config.{sub, guess} using autotools hook perl may fail to build on newer host architectures such as aarch64 due to its inability to guess the host architecture to build 'miniperl', which is built during the process. An error message looks like this: Configuring build-time miniperl for unknown ERROR: No $target defined (?!) ERROR: configure --mode=buildmini failed This happens because the config.sub and config.guess files from perl are not modified and may become outdated. These files are normally updated automatically by a Buildroot hook for autotools packages, to avoid problems like these. Although perl uses the config.sub and config.guess files, it is not a strict autotools package, so it is not defined as an "autotools-package" in Buildroot and so it doesn't inherit the hook. This commit makes perl borrow the hook from the autotools infrastructure so that it can build on newer build architectures. This has been tested by building it on an aarch64 host machine.
