Question

Is it possible to create objects files in makefile depending on the name of the target?

something like

all : gsm gsm_db

if make gsm
%.o : %.cpp
    $(CC) $(CFLAGS) $< -o $@

if make gsm_db
%.o : %.cpp
    $(CC) $(CFLAGS_DB) $< -o $@

Answer 1

Something like this should work:

ifneq "$(filter gsm_db, $(MAKECMDGOALS))" ""
%.o : %.cpp
    $(CC) $(CFLAGS_DB) $< -o $@
else
%.o : %.cpp
    $(CC) $(CFLAGS) $< -o $@
endif
