What is the $@ symbol for in a makefile?

  1. Aug 28, 2011 #1
    Hi.

    Can anyone please tell me what purpose $@ serves in the dependency line below? I've tried looking online, and in the make and ifort documentation, but can't find anything. :confused:

    Code (Text):

    $(EXECUTABLE) : $(OBJECTS)
                    ifort $(LOADFLAGS) -o $@ $(OBJECTS) $(LIBRARIES)
     
    where:

    OBJECTS = list of object files
    LOADFLAGS = -O3 -align dcommons
    LIBRARIES = -L$(LIBRARY) -lfft -lnetcdf

    Many thanks. :smile:
