| 21 | # RULES for creating the source code dependencies. |
|---|
| 22 | # |
|---|
| 23 | # These are typically used to implement the rules depend and clean_depend |
|---|
| 24 | # in other make rule files. |
|---|
| 25 | # |
|---|
| 26 | # 'generic_depend' creates the dependencies and appends them to a separate |
|---|
| 27 | # file in the same directory as the source code, called .depend. |
|---|
| 28 | # Depend uses some customized logic to determine the name of the source |
|---|
| 29 | # code file associated with each object file in OBJS. This means that we |
|---|
| 30 | # can mix source code extensions in the same library (e.g. use C and C++ |
|---|
| 31 | # source interchangeably). See compile_rules.mk for supported file name |
|---|
| 32 | # extensions for C and C++ development. |
|---|
| 33 | # |
|---|
| 34 | # 'generic_clean_depend' removes the dependencies file .depend. |
