# Makefile for NetBSD

|
|
# This makefile is constructed from a machine description:
|
|
# config machineid
|
|
# Most changes should be made in the machine description
|
|
# /sys/arch/sparc64/conf/``machineid''
|
|
# after which you should do
|
|
# config machineid
|
|
# Machine generic makefile changes should be made in
|
|
# /sys/arch/sparc64/conf/Makefile.sparc64
|
|
# after which config should be rerun for all machines of that type.
|
|
#
|
|
# To specify debugging, add the config line: makeoptions DEBUG="-g"
|
|
# A better way is to specify -g only for a few files.
|
|
#
|
|
# makeoptions DEBUGLIST="uvm* trap if_*"
|
|
|
|
# Default to 32-bit. Set the MACHINE_ARCH accordingly.
|
|
#
|
|
# You must also be using the correct toolchain or the kernel build
|
|
# will fail.
