Hello... I was wondering if anyone could give me some insight (==help). I am
writing a makefile that has a SINGLE command that generates multiple output
files. The difficulty I am running into is that the command is executed for
each dependency, where the command actually takes care of all of them in one
run.
Specifically (simplified greatly):
all: MyStuff.a
GENERATED_CXX=MyStuff.cpp MyStuff_skel.cpp
$(GENERATED_CXX) : MyStuff.idl
$(IDLGEN) $(IDLGENFLAGS) $<
MyStuff.a : $(patsubst %.cpp,%.o,$(GENERATED_CXX))
# archive them here
with the usual %.o:%.cpp rule elsewhere. What ends up happening is that
$(IDLGEN) is run twice (once for MyStuff.cpp, once for MyStuff_skel.cpp),
where I only want it done once.
Thanks
Derick
