NMAKE Fatal Error U1004

syntax error : macro name missing

One of the following occurred:

• The name of a macro being defined was itself a macro invocation that expanded to nothing. For example, if the macro named ONE is undefined or has a null value, the following macro definition causes this error:

  $(ONE)=TWO
  

• A macro invocation did not specify a name in the parentheses. The following specification causes this error:

  $()
  

The syntax for using a macro is:

$(name)
