| 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 | # |

| 43 | # Always make sure 'all' is the default rule |
