To fix this issue:

   -

   I cloned dtc from its
repositoryand
extracted the tarball to
   qemu/dtc/.
   -

   Compiled dtc from source first using make
   -

   Restarted configuring qemu.

The problem was qemu tries to search for dtc binaries in qemu/dtc. Even if
you have installed dtc using sudo apt-get install device-tree-compiler, you
will get the above error(mentioned in the question), so you probably need
to have the binaries in qemu/dtc.

Why not just do the git submodule command that the error message

into the qemu tree like this.

(1) You need the development libraries and headers, which for
Ubuntu are in "libfdt-dev", not "device-tree-compiler".
(2) If the system libfdt isn't sufficiently new/correctly built
we won't use it (in particular it has to provide /usr/include/libfdt_env.h)

So, the easiest way out, I believe was to clone it from its repositories.
Please let me
know the drawbacks of doing this.

I had installed libfdt-dev using apt-get but even that did not work, it
returned the same error.

Why not just do the git submodule command that the error message

from configure suggests? You don't need to manually stick the tarball
into the qemu tree like this.


When I did just that, it said i=

This looks like you didn't get qemu by cloning it from git (maybe you got
a tarball?). That's fine but it's not what you said you did...

Anyway, what you've done will work, it's just not something we expect
people to have to do.

If you take a snapshot then the git submodule commands won't work.
Generally we expect people will mostly either (a) take a release tarball,
which has the submodule sources included or (b) clone from git,
in which case the advice in the error message will work.

Anyway, you've got to a working compile now, but that's why you
ran into the problems you did, I think.
