Hi,
I'm trying to compile my C++ code in such a way, that I get all .o
files directly to specified folder.
I want to avoid creation of .o files in current dir and then copy them
over to desired one.
Could someone please tell me, why the follwoing makefile does nothing?
make says: Nothing to be done for 'lib'
I do not have any .o files created...
Try this:
######
CPPFLAGS = -I$(INC)
INC = ../Include
OUTL = ../output/Libs
MODULES = $(OUTL)/AmaSocket.o $(OUTL)/DbgLIB.o
lib : $(OUTL)/liasut.a
$(OUTL)/liasut.a : $(MODULES)
$(AR) -r $@ $^
$(OUTL)/DbgLIB.o : $(INC)/DbgLIB.h $(INC)/Dbg.h
$(OUTL)/%.o : %.cpp
$(CXX) -c -o $@ $< $(CPPFLAGS) $(CDEFS)
clean:
rm -f $(MODULES) $(OUTL)/liasut.a
##### END
Assuming this directory structure:
$ ls -lR
drwxr-xr-x 4 toby toby 136 Jul 31 10:29 Include
