| michael@0 | 8 | # The purpose of this file is to pull in non-recursive targets when performing |
| michael@0 | 9 | # a partial tree (not top-level) build. This will allow people to continue to |
| michael@0 | 10 | # build individual directories while some of the targets may not be normally |
| michael@0 | 11 | # defined in that make file. |
| michael@0 | 12 | # |
| michael@0 | 13 | # Non-recursive targets are attached to existing make targets. The |
| michael@0 | 14 | # NONRECURSIVE_TARGETS variable lists the make targets that modified. For |
| michael@0 | 15 | # each target in this list, the NONRECURSIVE_TARGET_<target> variable will |
| michael@0 | 16 | # contain a list of partial variable names. We will then look in variables |
| michael@0 | 17 | # named NONRECURSIVE_TARGETS_<target>_<fragment>_* for information describing |
| michael@0 | 18 | # how to evaluate non-recursive make targets. |
| michael@0 | 19 | # |
| michael@0 | 20 | # Targets are defined by the following variables: |
| michael@0 | 21 | # |
| michael@0 | 22 | # FILE - The make file to evaluate. This is equivalent to |
| michael@0 | 23 | # |make -f <FILE>| |
| michael@0 | 24 | # DIRECTORY - The directory whose Makefile to evaluate. This is |
| michael@0 | 25 | # equivalent to |make -C <DIRECTORY>|. |
| michael@0 | 26 | # TARGETS - Targets to evaluate in that make file. |
| michael@0 | 27 | # |
| michael@0 | 28 | # Only 1 of FILE or DIRECTORY may be defined. |
| michael@0 | 29 | # |
| michael@0 | 30 | # For example: |
| michael@0 | 31 | # |
| michael@0 | 32 | # NONRECURSIVE_TARGETS = export libs |
| michael@0 | 33 | # NONRECURSIVE_TARGETS_export = headers |
| michael@0 | 34 | # NONRECURSIVE_TARGETS_export_headers_FILE = /path/to/exports.mk |
| michael@0 | 35 | # NONRECURSIVE_TARGETS_export_headers_TARGETS = $(DIST)/include/foo.h $(DIST)/include/bar.h |
| michael@0 | 36 | # NONRECURSIVE_TARGETS_libs = cppsrcs |
| michael@0 | 37 | # NONRECURSIVE_TARGETS_libs_cppsrcs_DIRECTORY = $(DEPTH)/foo |
| michael@0 | 38 | # NONRECURSIVE_TARGETS_libs_cppsrcs_TARGETS = /path/to/foo.o /path/to/bar.o |
| michael@0 | 39 | # |
| michael@0 | 40 | # Will get turned into the following: |
| michael@0 | 41 | # |
| michael@0 | 42 | # exports:: |
| michael@0 | 43 | # $(MAKE) -C $(DEPTH) -f /path/to/exports.mk $(DIST)/include/foo.h $(DIST)/include/bar.h |
| michael@0 | 44 | # |
| michael@0 | 45 | # libs:: |
