Subject: [PATCH] configure: dtc: Probe for libfdt_env.h
81a3da
81a3da
Currently QEMU provides a local clone of the file libfdt_env.h in
81a3da
/include. This file is supposed to come with the libfdt package and is
81a3da
only needed for broken installs of libfdt. Now that we have submodule
81a3da
dtc, just ignore these broken installs and prompt for the dtc submodule
81a3da
install instead. QEMU's local libfdt_env.h is removed accordingly.
81a3da
81a3da
Manifests as a bug when building QEMU with modern libfdt. The new
81a3da
version of libfdt does not compile when QEMUs libfdt_env.h takes
81a3da
precedence over the hosts.
