It search at first in the local dir where "test1.c" is stored for the "ieee802154.h" header. Which means it's a local header. A fallback behaviour of gcc will search this header in your given include path which are given by -I and -stdinc gcc arguments. What I can told you now that we don't deliver any headers into userspace side with the kernel-headers. So this header comes from the lowpan-tools package. Maybe tyoe a `find -name "ieee802154.h" $LOWPAN_TOOLS_DIR` in your shell, to find it or whereever your include paths belongs to which are given over "-I" of gcc call. - Alex -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
