| 9 | Override the default build_clib behaviour to do the following: | |
| 10 | ||
| 11 | 1. Implement a rudimentary timestamp-based dependency system | |
| 12 | so 'compile()' doesn't run every time. | |
| 13 | 2. Add more keys to the 'build_info' dictionary: | |
| 14 | * obj_deps - specify dependencies for each object compiled. | |
| 15 | this should be a dictionary mapping a key | |
| 16 | with the source filename to a list of | |
| 17 | dependencies. Use an empty string for global | |
| 18 | dependencies. | |
| 19 | * cflags - specify a list of additional flags to pass to | |
| 20 | the compiler. | |
