| 8 # The purpose of this file is to pull in non-recursive targets when performing | |
| 9 # a partial tree (not top-level) build. This will allow people to continue to | |
| 10 # build individual directories while some of the targets may not be normally | |
| 11 # defined in that make file. | |
| 12 # | |
| 13 # Non-recursive targets are attached to existing make targets. The | |
| 14 # NONRECURSIVE_TARGETS variable lists the make targets that modified. For | |
| 15 # each target in this list, the NONRECURSIVE_TARGET_<target> variable will | |
| 16 # contain a list of partial variable names. We will then look in variables | |
| 17 # named NONRECURSIVE_TARGETS_<target>_<fragment>_* for information describing | |
| 18 # how to evaluate non-recursive make targets. | |
| 19 # | |
| 20 # Targets are defined by the following variables: | |
| 21 # | |
| 22 # FILE - The make file to evaluate. This is equivalent to | |
| 23 # |make -f <FILE>| | |
| 24 # DIRECTORY - The directory whose Makefile to evaluate. This is | |
| 25 # equivalent to |make -C <DIRECTORY>|. | |
| 26 # TARGETS - Targets to evaluate in that make file. | |
| 27 # | |
| 28 # Only 1 of FILE or DIRECTORY may be defined. | |
| 29 # | |
| 30 # For example: | |
| 31 # | |
| 32 # NONRECURSIVE_TARGETS = export libs | |
| 33 # NONRECURSIVE_TARGETS_export = headers | |
| 34 # NONRECURSIVE_TARGETS_export_headers_FILE = /path/to/exports.mk | |
| 35 # NONRECURSIVE_TARGETS_export_headers_TARGETS = $(DIST)/include/foo.h $(DIST)/include/bar.h | |
| 36 # NONRECURSIVE_TARGETS_libs = cppsrcs | |
| 37 # NONRECURSIVE_TARGETS_libs_cppsrcs_DIRECTORY = $(DEPTH)/foo | |
| 38 # NONRECURSIVE_TARGETS_libs_cppsrcs_TARGETS = /path/to/foo.o /path/to/bar.o | |
| 39 # | |
| 40 # Will get turned into the following: | |
| 41 # | |
| 42 # exports:: | |
| 43 # $(MAKE) -C $(DEPTH) -f /path/to/exports.mk $(DIST)/include/foo.h $(DIST)/include/bar.h | |
| 44 # | |
| 45 # libs:: | |
| 46 # $(MAKE) -C $(DEPTH)/foo /path/to/foo.o /path/to/bar.o | |
