I was going to submit exactly the same patch...
However during my tests, I noticed that except for the 1.4.4 version, all
the next ones are failing.
It produces a LOT of warnings and fails with

error: redefinition of ?fdt16_to_cpu'

And many other ones...

I didn't found a way to fix that right now...

Regards,
David.

This is failing all over the place in the autobuilders:

  http://autobuild.buildroot.net/?reason=%dtc-1.4.7

Could you look into those issues and provide a patch to address them ?

Thanks!

[Buildroot] [PATCH v1 1/2] dtc: bump version to 1.4.7

[Geoff Levand]

Hi Simon,

Any ideas about what's wrong?

Some builds show this error:

  LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)

Which seems to be triggered from this:

  https://github.com/python/cpython/blob/e42b705188271da108de42b55d9344642170aa2b/Include/pyport.h#L701

I'll continue to look into it.

-Geoff

[Buildroot] [PATCH v1 1/2] dtc: bump version to 1.4.7

Hi Simon,

After looking at it a bit more, it seems setup.py is using the host
toolchain (/usr/bin/gcc), and not the cross toolchain when linking.

Any idea how to fix this?

[Buildroot] [PATCH v1] dtc: Add set-ldshared.patch

Fixes pylibfdt cross compile errors.

Hi Thomas,

This gets the dtc package to build with python support, but
it seems the real problem is that python distutils doesn't
set LDSHARED correctly, which should default to CC.

Are you sure your patch is fixing the host-dtc build issues ?

I am seeing two different build issues:

 - One for host-dtc, which looks like this:

	 INSTALL-PYLIB

 - One for dtc, which looks like this:

Your patch probably fixes the "dtc" issue, but I'm not sure it fixes the host-dtc issue.

Since all those problems are due to pylibfdt, which is new since 1.4.5,

NO_PYTHON=1 so that we don't build the Python support, even if the
