From mboxrd@z Thu Jan 1 00:00:00 1970 From: Baruch Siach Date: Fri, 14 Apr 2017 08:27:37 +0300 Subject: [Buildroot] [PATCH] trinity: fix ipv6 headers detection Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net The trinity configure script looks into a host header to check for libc/kernel headers conflict resolution. This is not compatible with cross compilation. Add a patch that does direct compilation test instead. This issue was not caught by the autobuilder yet.
