# generic_leaf_target
|
|
#
|
|
# Generate a set of basic targets (all, clean, install) for a leaf directory
|
|
# (no subdirectories).
|
|
#
|
|
# $(MAKE_DEPS) : What should we execute beforehand as a
|
|
# dependency of $(MAKE_TARGETS)?
|
|
#
|
|
# $(INSTALL_FILES) -> install
|
|
#
|
|
# Helpful variables are:
|
|
#
|
|
# $(MAKE_TARGETS) : What to execute as direct dependencies of
|
|
# all.
|
|
# 1. Defaults to the basename of the targets
|
|
# produced by the %.c -> % implicit pattern
|
|
# rules, e.g. the MAKE_TARGET in a directory
|
|
# like the following:
|
|
#
|
|
# $$ ls /bar
|
|
# foo.c
|
|
#
|
|
# Would be `foo'. Similarly, the following
|
|
# dir structure:
|
|
#
|
|
# $$ ls /bar
|
|
# foo.c zanzibar.c
|
|
#
|
|
# Would be `foo zanzibar'.
|
|
#
|
|
# 2. If you define MAKE_TARGETS as an empty
|
|
# string, this will override the defaults.
|
|
# I did this to avoid providing too much
|
|
# rope to hang one's self in the event of
|
|
# unwanted behavior.
|
|
#
|
|
# $(HOST_MAKE_TARGETS) : Host tools which use $HOSTCC.
|
|
#
|
|
# $(CLEAN_TARGETS) : What targets should be cleaned (must be
|
|
# real files or directories). This will automatically append
|
|
# adds the .o suffix to all files referenced by
|
|
# $(MAKE_TARGETS)) to CLEAN_TARGETS, if MAKE_TARGETS wasn't
|
|
# defined (see
|
|
# $(MAKE_TARGETS)).
|
|
# $(INSTALL_MODE) : What mode should we using when calling
|
|
# install(1)?
|
|
#
|
|
# Also, if you wish to change the installation directory, from the set default
|
|
# (testcases/bin) you must do something like either one of the following items:
|
|
#
|
|
# Method A:
|
|
#
|
|
# INSTALL_DIR := /path/to/installdir/from/$(DESTDIR)/$(prefix)
|
|
#
|
|
# e.g. if I wanted to install my binaries in testcases/bin, I would do:
|
|
#
|
|
# INSTALL_DIR := testcases/bin
|
|
#
|
|
# in my calling Makefile.
|
|
#
|
|
# Or Method B:
|
|
#
|
|
# INSTALL_DIR := /path/to/installdir/from/$(DESTDIR)
|
|
#
|
|
# e.g. if I wanted to install my binaries in $(libdir) (which may not exist
|
|
# outside of $(prefix) right now, but could in the future), I could do the
|
|
# following:
|
|
#
|
|
# INSTALL_DIR := $(libdir)
|
|
#
|
|
|
