Hi,
I have a problem with target-pecific variables. A Makefile to demonstrate
it
<file>
a = 1
bug: a +=
again-work: a +=
again-work: a += 2
work bug again-work:
@echo "$@: a = $(a)"
</file>
I expect
$ make bug
bug: a = 1
But I see only
$ make bug
bug: a =
The other targets give me no surprise
$ make work
work: a = 1
$ make again-work
again-work: a = 1 2
I'm using make-3.80 with eval-conditional and eval-crash patches on a
Linux RedHat-7.3 machine.
Sincerely,
Makim Nikulin
