Hi! I'm using GNU Make 3.80. In my Makefile, I use automatic variable $@ to refer to the current target, as shown below.

       |     @echo current target is ... address@hidden
       ifeq ($@,sms)
            @echo yep, they are equal
            @echo no, they are not equal

It seems that $@  expands to sms , as shown in the output below.

Output is:

       |current target is ... [sms]
       no, they are not equal

My question: since $@ (apparently) expands to sms , shouldn't the "true" branch of the ifeq conditional be executed (with the consequence that the output should read yep, they are equal)? [I am at a loss as to why the output is no, they are not equal.]

Thank you for any advice you can provide.
