Update of bug #37237 (project make):
Status: None => Not A Bug
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #1:
GNU make's behavior here is correct. Because the ":" does not appear within a
known macro reference (because the "$" is escaped), it's treated as part of
the rule. This makes the rule appear to be a static pattern rule, which is
missing a "%", and hence the error. In other words, make parses this into
words as follows: "dir/hello.o", ":", "$$(@F", ":", and ".o=.c)".
To make this work right you need to escape the ":" from make, like so:
dir/hello.o: $$(@F\:.o=.c)
This works in CVS make but I'm not sure it will work in earlier versions;
there have been some issues with escaping in target and prerequisite lists.
