|
# Notes:
|
|
# * no obj dir support
|
|
# * kernel headers are supposed to exist, i.e. they're not
|
|
# expected to be built.
|
|
#
|
|
# System configuration variables:
|
|
#
|
|
# SYS_INCLUDE "symlinks": symlinks to include directories are created.
|
|
# This may not work 100% properly for all headers.
|
|
#
|
|
# "copies": directories are made, if necessary, and headers
|
|
# are installed into them.
|
|
#
|
|
# Variables:
|
|
#
|
|
# INCSDIR Directory to install includes into (and/or make, and/or
|
|
# symlink, depending on what's going on).
|
|
#
|
|
# KDIR Kernel directory to symlink to, if SYS_INCLUDE is symlinks.
|
|
# If unspecified, no action will be taken when making include
|
|
# for the directory if SYS_INCLUDE is symlinks.
|
|
#
|
|
# INCS Headers to install, if SYS_INCLUDE is copies.
|
|
#
|
|
# SUBDIR Subdirectories to enter
|
|
#
|
|
# SYMLINKS Symlinks to make (unconditionally), a la bsd.links.mk.
|
|
# Note that the original bits will be 'rm -rf'd rather than
|
|
# just 'rm -f'd, to make the right thing happen with include
|
|
# directories.
