Filename Macros
The latest version of this topic can be found at Filename Macros.
Filename macros are predefined as filenames specified in the dependency (not full filename specifications on disk). These macros do not need to be enclosed in parentheses when invoked; specify only a $ as shown.
| Macro | Meaning |
|---|---|
| $@ | Current target's full name (path, base name, extension), as currently specified. |
| $$@ | Current target's full name (path, base name, extension), as currently specified. Valid only as a dependent in a dependency. |
| $* | Current target's path and base name minus file extension. |
| $** | All dependents of the current target. |
| $? | All dependents with a later timestamp than the current target. |
| $< | Dependent file with a later timestamp than the current target. Valid only in commands in inference rules. |
To specify part of a predefined filename macro, append a macro modifier and enclose the modified macro in parentheses.
| Modifier | Resulting filename part |
|---|---|
| D | Drive plus directory |
| B | Base name |
| F | Base name plus extension |
| R | Drive plus directory plus base name |
