Title
Body
I have a Makefile with a set of booleans which must be used to control the flags for an external application. The problem is that the flag must be passed as a comma-separated string. Something like this (non-working pseudo code): WITH_LIST = "" WITHOUT_LIST = "" ifeq ($(BOOL_A),y) # Append A to list "WITH_LIST" else # Append A to list "WITHOUT_LIST" endif ifeq ($(BOOL_B),y) # Append B to list "WITH_LIST" else # Append B to list "WITHOUT_LIST" endif ifeq ($(BOOL_C),y) # Append C to list "WITH_LIST" else # Append C to list "WITHOUT_LIST" endif Now assuming BOOL_A == y, BOOL_B == n and BOOL_C == y, I need to run the following command: ./app --with=A,C --with-out=B How can I generate these string using Gnu Make?
