From patchwork Sun Jan 20 23:52:21 2013 Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Subject: [RFC,v1,12/14] autoconf: fix out-of-tree build From: Thomas Petazzoni X-Patchwork-Id: 214005 Message-Id: <1358725943-31485-13-git-send-email-thomas.petazzoni@free-electrons.com> To: buildroot@uclibc.org Date: Mon, 21 Jan 2013 00:52:21 +0100 Even though one might think that autoconf should have been the best example of a clean and nice example of a correct out of tree build implementation, this is not the case. The autoconf build process makes modification to the source tree, for some obscure updating process of manual pages. For now, we workaround this problem by re-adding write permissions on the man/ subdirectory of autoconf sources, but on the long term, a proper, upstreamable solution would be better.
