No.  The example works.

Please run "make --version".  The online manual documents the currently
released version of GNU make.  The eval function was added in GNU make
3.80, which was released in 2002.  If your version of GNU make is older
than that, then $(eval ...) will not work for you.

If your version is 3.80 or newer, please cut/paste (exactly) your
makefile so we can see it.
