So is there > a missing dependency / check when cross building? Well, standard builds are allowed to fall back to using the regular tools on the box (e.g. /usr/bin/make). Perhaps that shouldn't happen for cross-builds. cc'ing ru@ as he would know better about that than I. Maybe TMPPATH should just be STRICTTMPPATH if TARGET is set? > Now I know that option searching for kernel-toolchain turned up the information > in "man build" which seems to have similar but more info than the header of:- > /usr/src/Makefile > > It might be nice to have a reference "man build" in the header to help others > who try to do the same thing and ensure they don't hit the same brick wall I > did. Something like this perhaps?
