Hi there,

I am building a make file to compile many .cpp files in different
directories, and save .o files into one directory. All source file
names are different.

For example:
/prj/cmn/cmn.cpp
/prj/prj1/prj1.cpp
/prj/prj1/main.cpp

Save .o files to
/out/prj1/cmn.o
/out/prj1/prj1.o
/out/prj1/main.o

I trid to do it like this,

SOURCES := /prj/cmn/cmn.cpp /prj/prj1/prj1.cpp /prj/prj1/main.cpp
OBJECTS := $(addprefix $(OBJDIR)/, $(addsuffix .o, $(basename $(notdir
$(SOURCES)))))

all: /out/prj1/prj1

/out/prj1/prj1 : $(OBJECTS)
        $(LINK.cpp) $(DBG_OPTS) -o /out/prj1/prj1 $(OBJECTS)

/out/prj1/%.o : %.cpp
        $(COMPILE.cpp) $(DBG_OPTS) -o $@ $<

But it does not work.
Please help me. Thanks in advance.
