It _does_ work, again assuming you have a "new enough" version of make.
You still haven't provided any information on what version you're
using.  You need GNU make 3.80 or better to use this feature.

As I said, though, I suspect that what you are trying to do doesn't make
sense; in this case $(eval ...) won't help you.  But since you didn't
tell us what you want to do, it's the best we can offer.

If you want more help you'll need to put more effort into asking for it,
and provide us with some details.


FYI, this example proves that the $(eval ...) method works:

  $ cat Makefile
  FOO = foo
  one: two ; @echo $(FOO)
  two: ; $(eval FOO = bar)

  $ make
  bar

  l> Is there an alternate way of doing this assignment within a rule?

No.
