It seems I'm doing something very wrong, but I fail to see what.
In my attempts to hack netbooting I need to build netboot from the
sources (surprise). Netboot is not built by default:
# $FreeBSD: src/sys/boot/alpha/Makefile,v 1.5 1999/09/09 01:28:26 mjacob Exp
$
SUBDIR= libalpha
SUBDIR+= boot1 loader cdboot
.include <bsd.subdir.mk>
The problem is that a make in the netboot subdirectory produces .o files
in that directory, whereas (e.g.) cdboot puts it's .o files in /usr/obj
The subsequent 'ld' has problems linking things in because it looks in
the wrong place (see below).
From looking at the respective makefiles I fail to understand why this
happens. It's probably a .include or so hiding deep below. But where??
Appreciate any help here,
Wilko
