# This makefile is simple by design. The FreeBSD make automatically reads
|
|
|
|
# the /usr/share/mk/sys.mk unless the -m argument is specified on the
|
|
|
|
# command line. By keeping this makefile simple, it doesn't matter too
|
|
|
|
# much how different the installed mk files are from those in the source
|
|
|
|
# tree. This makefile executes a child make process, forcing it to use
|
|
|
|
# the mk files from the source tree which are supposed to DTRT.

# If at first you're a little nervous about having a `make world' update
|
|
|
|
# your system, a `make buildworld' will build everything in the /usr/obj
|
|
|
|
# tree without touching your installed system. To be of any further use
|
|
|
|
# though, a `make installworld' is required.

# The `make world' process always follows the installed object format.
|
|
|
|
# This is set by creating /etc/objformat containing either OBJFORMAT=aout
|
|
|
|
# or OBJFORMAT=elf. If this file does not exist, the object format defaults
|
|
|
|
# to aout. This is expected to be changed to elf just prior to the release
|
|
|
|
# or 3.0. If OBJFORMAT is set as an environment variable or in /etc/make.conf,
|
|
|
|
# this overrides /etc/objformat.

# Unless -DNOAOUT is specified, a `make world' with OBJFORMAT=elf will
|
|
|
|
# update the legacy support for aout. This includes all libraries, ld.so,
|
|
|
|
# lkms and boot objects. This part of build should be regarded as
|
|
|
|
# deprecated and you should _not_ expect to be able to do this past the

# release of 3.1. You have exactly one major release to move entirely

|
