I am learning make and ran across a few commands that I do not understand. Can anyone help me understand these commands please?
I have the following few lines from a larger make file.
blank :=
blank +=
type_switcher = $(or\
$(if $(subst TEMP_WEIGHT,,$(firstword $(subst _,$(blank),$(1)))),,$(blank)),\
$(if $(subst TEMP_SPEED,,$(firstword $(subst _,$(blank),$(1)))),,-temp_speed),\
$(if $(subst TEMP_MASSN,,$(firstword $(subst _,$(blank),$(1)))),,-temp_mass -temp_massn),\
$(error No known type defined in command $(2)))
What is $(1) in this code?
Is there a way to print out all the variables fully expanded but without actually running make?
