This was fixed in GNU make 3.82 (released July 2010):

$ make-3.81

$ make-3.82
make: *** No rule to make target `a.c', needed by `a.o'.  Stop.

Upgrade.  This was fixed some time in the last five years.

May be related to #29074, but doesn't sound like a duplicate.

Consider the following makefile:


# Remove ALL default rules
.SUFFIXES:
(%): %
%.out: %
%.c: %.w %.ch
%.tex: %.w %.ch
%:: %.v
%:: RCS/%,v
%:: RCS/%
%:: s.%
%:: SCCS/s.%

SOURCES = a.c b.c

OBJS = $(SOURCES:%.c=%.o)

DEPFILES = $(SOURCES:%.c=%.c.d)

EXE = a

.PHONY: all
all: $(EXE)

$(DEPFILES): %.c.d : %.c
        @echo "Determining dependencies for $(<F)"
        @$(CC) -E -MM -MF$@ -MP $<

$(OBJS): %.o: %.c
        @echo "Compiling $(<F)"
        @$(CC) -c $< -o $@

$(EXE): $(OBJS)
        @echo "Linking $(@F)"
        @$(CC) $+ -o $@

# This seems to be the troublemaking line!
-include $(DEPFILES)


If one or both source files do not exist, processing for the -include directive notices this, but generates no error, I suppose because of the -include. By the time it gets to the other targets, however, the already-processed files are "Pruned." The end result is no generated error message, but make exits with a status of 2. (Sorry, I'd love to give the output of a make -d on this, but my Linux machine is on an isolated secured network. For similar reasons I am unable to see if this has been fixed in later versions, though perusing the bug list tells me it has not.)
