| 27 # Makefile for linking with mapfiles. | |
| 28 # | |
| 29 # NOTE: Not using a mapfile will expose all your extern functions and | |
| 30 # extern data symbols as part of your interface, so unless your | |
| 31 # extern names are safe from being mistaken as names from other | |
| 32 # libraries, you better use a mapfile, or use a unique naming | |
| 33 # convention on all your extern symbols. | |
| 34 # | |
| 35 # The mapfile will establish versioning by defining the exported interface. | |
| 36 # | |
| 37 # The mapfile can also force certain .o files or elf sections into the | |
| 38 # the different segments of the resulting library/program image. | |
| 39 # | |
| 40 # The macro FILES_m can contain any number of mapfiles. | |
| 41 # | |
| 42 | |
| 43 # Always make sure 'all' is the default rule | |
| 44 mapfile_default_rule: all | |
