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!

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.

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

[Geoff Levand]

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

[Geoff Levand]

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
pylibfdt/libfdt_wrap.c: In function 'SWIG_Python_NewShadowInstance':
pylibfdt/libfdt_wrap.c:2483:65: error: declaration of 'swig_this' shadows a global declaration [-Werror=shadow]

pylibfdt/libfdt_wrap.c:2224:18: error: shadowed declaration is here [-Werror=shadow]
 static PyObject *swig_this = NULL;

 - One for dtc, which looks like this:

	 LD fdtoverlay
/usr/bin/ld: build/temp.linux-x86_64-2.7/usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/build/dtc-1.4.7/libfdt/fdt.o: Relocations in generic ELF (EM: 8)

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

Patches should be Git formatted, have a description and a Signed-off-by.

Do we know why it was working before, and why it fails since the dtc update ?

Since all those problems are due to pylibfdt, which is new since 1.4.5,
and that we don't use in Buildroot, I applied a simpler fix: pass
NO_PYTHON=1 so that we don't build the Python support, even if the
necessary dependencies are found.

See:

OK, great.  Thanks for looking into it.
