Summary | 0000866: No precedence between include lines and macro definitions | ||||||
Description |
The Standard does not prescribe an order of evaluation between include lines and macro definitions. Furthermore, various implementations chose distinct interpretations forinclude =foo.mk Given the low actual usefulness of such a construct, it does not seem important to try to choose between interpretations (which would automatically render the other half of the implementations theoretically not conforming.) Rather, we could suggest workarounds to let applications avoid the pitfall. |
||||||
Desired Action |
Add a new paragraph to RATIONALE after P2928, L96368: The standard does not prescribe the precedence between include lines and macro definitions. As such, the effect of include =foo.mk is unspecified. To define a variable named include, either the whitespace before the <equal-sign> should be removed, or another macro should be used, as in INCLUDE_NAME = include $(INCLUDE_NAME) =foo.mk On the other hand, if the intent is to include a file which starts with an <equal-sign>, the makefile should be written as INCLUDE_FILE = =foo.mk include $(INCLUDE_FILE) |
