# Generic configuration for Hurd compilation

all:

# This is the directory into which Hurd cross-building tools are placed
hurdinst := /home/hm1/hurdinst

# This is the directory which serves as root for the Hurd.
hurdroot := /home/hm1/hurdroot

# This is the directory containing the top-level Hurd source (and this file).
hurdsource := /home/hm1/gnu/hurd

# This is the directory holding ar and ranlib
bindir := /usr/local/i386-mach/bin

# This is a machine on which to run MiG.  (MiG writes CPU dependent code,
# so MiG has to be run on a machine that's the same as the one that will 
# run the eventual code.)  If you are not doing cross-compilation, then
# you need to set MIGCOM and MIG below to the plain pathnames of those
# two programs respectively.
mighost := ernst

# Set these options to the GCC compiler spec (the correct value
# can be found in /usr/local/lib/lib-gcc).
