I've posted the relevant bits of my makefile. When I run make all
on this makefile, there's a compilation error when compiling debugosd.o
. However, because make found a previously built debugosd.o
, it just continues on to build dialup.otz
.
Without deleting all the .o's, how can I force debugosd.o
to become out-of-date - and so force make
to stop as soon as it hits the compilation error in debugosd.o
?
The rule to build .o files is:
%.o: %.c
$(TITLE)
$(CC) $(COMPILE) $(C_OPTIONS) -c $<
And the makefile snippet is:
all: shared0.flw shared1.flw shared2.flw shared3.flw
debugosd.o: debugosd.c debugosd.h
xdialler_interface_new.o: xdialler_interface.h
dialup.ooo: xdialler_interface_new.o debugosd.o xDialler.a
$(TITLE)
$(MAKE_OOO)
dialup.otz: dialup.ooo
$(BIN)opress $<
shared1.dir: dialup.otz
$(TITLE)
$(BIN)dirbuild $(SHAREDDIR1_OPTIONS)
shared1.flw: shared1.dir
$(TITLE)
$(BIN)flwbuild $(SHAREDFLW_OPTIONS1)
Actually, I figured out what the problem was. I was forcing the rebuild of shared1.flw
using a phony target. I think this was then forcing make
to continue regardless of errors.
