Hi All
I try to compile a device tree from sources that are lying in the barebox tree.
The device tree uses #includes and #defines that should be processed by the
CPP. When I run the dtc.targetinstall step, I get the following error:
--------------------
target: imx6-foo.dtb
--------------------
CPP ptxdist_project/platform-foo/state/imx6-foo.dts.tmp
/bar/ptxdist_project/platform-foo/build-target/barebox/arch/arm/dts/imx6-foo.dts:14:26:
fatal error: arm/imx6q.dtsi: No such file or directory
#include <arm/imx6q.dtsi>
^
compilation terminated.
The path arm/imx6q.dtsi is under a different include directory:
/bar/ptxdist_project/platform-foo/build-target/barebox/dts/src
I added the include path both like so:
PTXCONF_DTC_OFTREE_DTS_PATH=${BAREBOX_DIR}/arch/arm/dts:${BAREBOX_DIR}/dts/src
And so:
DTC_EXTRA_ARGS=-i ${BAREBOX_DIR}/dts/src
But the former only seems to be used to search for the .dts file and the latter
is only passed to dtc, not the preprocessor that runs before it. I looked at
the cpp command invocation that causes the problem:
cpp \
-Wp,-MD,${tmp_deps} \
-Wp,-MT,${tmp_dts} \
-nostdinc \
${no_linemarker} \
-I$(dirname "${dts}") \
-I${dts_kernel_dir}/arch/${dts_kernel_arch}/boot/dts \
-I${dts_kernel_dir}/arch/${dts_kernel_arch}/boot/dts/include \
-I${dts_kernel_dir}/drivers/of/testcase-data \
-I${dts_kernel_dir}/include \
-undef -D__DTS__ -x assembler-with-cpp \
-o ${tmp_dts} \
${dts} &&
Which only seems really work for device trees that are stored in the kernel
source tree (or need no include directories). So is it currently not possible
to use custom include directories for the device tree or do I go about it the
wrong way?
I am using ptxdist-2015.02.0, but the current master looks like it works the
same way.
Regards
Florian
