From a1dfd9b44ffb915fc6673b8f6f512ecf6489d628 Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Mon, 27 May 2013 14:20:57 +1000 Subject: [PATCH] configure: dtc: Probe for libfdt_env.h Currently QEMU provides a local clone of the file libfdt_env.h in /include. This file is supposed to come with the libfdt package and is only needed for broken installs of libfdt. Now that we have submodule dtc, just ignore these broken installs and prompt for the dtc submodule install instead. QEMU's local libfdt_env.h is removed accordingly. Manifests as a bug when building QEMU with modern libfdt. The new version of libfdt does not compile when QEMUs libfdt_env.h takes precedence over the hosts.
