I have set up my makefile like below, to minimize code duplication
The recipes are a set of blocks that set a variable, and then run the sleeper_agent recipe. They work great when called individually as make xlsx_sleeper for example.
But when I call all_sleepers, only the first one (xlsx_sleeper) gets compiled.
I have tried declaring them as phony (.PHONY: all_sleepers xlsx_sleeper docx_sleeper pptx_sleeper pdf_sleeper png_sleeper), which changes nothing
and adding a .FORCE rule to the sleeper_agent rule, which results in no such file or directory:
.FORCE:
sleeper_agent: .FORCE [...]
Here is my makefile:
all_sleepers: xlsx_sleeper docx_sleeper pptx_sleeper png_sleeper pdf_sleeper
sleeper_agent: $(OBJ)/sleeper_agent.o $(OBJ)/identities.o
windres icons/$(ext)/resource.rc -O coff -o obj/$(ext).res
$(CC) -o $(BIN)/sleeper_$(ext).exe $^ $(OBJ)/$(ext).res $(CFLAGS) $(LIBS)
xlsx_sleeper: ext=xlsx
xlsx_sleeper: sleeper_agent
docx_sleeper: ext=docx
docx_sleeper: sleeper_agent
pptx_sleeper: ext=pptx
pptx_sleeper: sleeper_agent
png_sleeper: ext=png
png_sleeper: sleeper_agent
pdf_sleeper: ext=pdf
pdf_sleeper: sleeper_agent
Your problem is that make does not see any reason why it should rebuild the sleeper_agent target several times. You should probably stick to the make philosophy:
$(BIN)/sleeper_xlsx.exe).all_sleepers, xlsx_sleeper, ...)clean, help...).PHONY: ...)Example using static pattern rules, automatic variables and the patsubst make function:
SLEEPER := xlsx docx pptx png pdf
EXE := $(patsubst %,$(BIN)/sleeper_%.exe,$(SLEEPER))
SHORT := $(patsubst %,%_sleeper,$(SLEEPER))
.PHONY: all_sleepers $(SHORT) clean_sleepers
all_sleepers: $(EXE)
$(SHORT): %_sleeper: $(BIN)/sleeper_%.exe
$(EXE): $(BIN)/sleeper_%.exe: $(OBJ)/sleeper_agent.o $(OBJ)/identities.o
windres icons/$*/resource.rc -O coff -o obj/$*.res
$(CC) -o $@ $^ $(OBJ)/$*.res $(CFLAGS) $(LIBS)
clean_sleepers:
rm -f $(EXE)
And then you should be able to run:
make all_sleepers
to build them all or:
make xlsx_sleeper
to build only one of them. EXE is the list of real executable files and a static pattern rule explains how to build them. In its recipe the $* automatic variable expands as the string matching the % wildcard. SHORT is the list of xxxx_sleeper shortcuts and another static pattern rule explains for each of them to which real executable it corresponds. all_sleepers and the xxxx_sleeper shortcuts (plus the clean_sleepers I added as example) are properly declared as phony because there are no such real files.
