Hello im referring to this chapter https://www.gnu.org/software/make/manual/make.html#Secondary-Expansion
and im referring to this example here: The following example will help illustrate these behaviors: .SECONDEXPANSION: foo: foo.1 bar.1 $$< $$^ $$+ # line #1 foo: foo.2 bar.2 $$< $$^ $$+ # line #2 foo: foo.3 bar.3 $$< $$^ $$+ # line #3 In the first prerequisite list, all three variables ($$<, $$^, and $$+) expand to the empty string. In the second, they will have values foo.1, foo.1 bar.1, and foo.1 bar.1 respectively. In the third they will have values foo.1, foo.1 bar.1 foo.2 bar.2, and foo.1 bar.1 foo.2 bar.2 foo.1 foo.1 bar.1 foo.1 bar.1 respectively. please could you tell me how* foo.1 bar.1 foo.2 bar.2 foo.1 foo.1 bar.1 foo.1 bar.1* is derived?
