  colleague has a kernel-compile infrastructure which builds the kernel just fine, but croaks trying to compile .dts files, complaining that there is no "./scripts/dtc/dtc" file.

  ok, so that sounds like whatever it is that compiles dtc.c (and friends) into dtc is being omitted. i just want to test whatever make target would normally compile that, but i'm having trouble figuring which make processing does that.

  is there a top-level target that wanders into scripts/dtc, and compiles that?

for a ARM target you could try to (PowerPC or MIPS should work too) export ARCH=arm make mxs_defconfig # random arm defconfig make dtbs this should build the devicetree compiler and the devicetree sources, but AFAIK newer kernel versions uses the dtc from the Host system. So it's possible that the dtc is omitted. Regards

p.s. i'm testing this on x86, which typically doesn't use dtb files, and there are no .dts files, so i'm looking for the target that would normally compile into "dtc", even though there's nothing that really needs it, if that makes a difference.

i thought "make scripts_dtc" would do it, but that didn't seem to make any difference. thoughts?
