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