OK, I looked into this problem because I, too, suspected it was MY
problem, not GNU make's. But unfortunately (or fortunately!) I was able
to duplicate it reliably:
Make a makefile like this in /var/tmp/tree1:
vpath % /var/tmp/tree2
%.class : %.java
@echo Star: $*
@echo Caret: $^
@echo At: $@
Then put (empty file; contents don't matter) Foo.java in
/var/tmp/tree1. Run make Foo.class. You should see (as you'd expect):
Star: Foo
Caret: Foo.java
At: Foo.class
Now move /var/tmp/tree1/Foo.java to /var/tmp/tree2/Foo.java (i.e. move
the source file into the vpath). Run make Foo.class. You see:
Star: Foo
Caret: /var/tmp/tree2/Foo.java
At: Foo.class
Oopsie; "Star" should be /var/tmp/tree2/Foo.java just like "Caret", yes?
The workaround seems to be to use $(filter) or $(filter-out) on $^
depending on what you want to do with $*.
GNU make 3.78.1 on Solaris 2.7.
