Let me tell an example.
I found the bayesSurv package in CRAN. It has some .cpp and .h files, and doesn't have a makefile. I did the following steps:
1. compile the package (R CMD INSTALL) 2. write something in /src/List.cpp (only add an empty line) 3. recompile package (INSTALL) it works, OK. 4. write something in /src/List.h 5. recompile it does nothing. List.cpp was not changed and so R says List.o is up to date, right?
Is there any way to tell R that List.o depends on List.h???
I think it is not an R problem, because Makefiles can check it. My question is: I know that List.o is not up to dated, because I changed List.h, and my Makefile recognizes it. But if I tell R to compile List.cpp again using COMPILE, it will say that the file is up to date, and won't compile it. So, the only way to check dependencies, as I can see, is using a Makefile, and compiling .cpp files without any R help. Is it true?
As I said before, COMPILE is not the correct tool. Please don't expect me to keep repeating myself.
BTW, R CMD INSTALL under Windows does build dependencies, and you have not specified your platform here.

I am developing a package with a lot of C++ code, and I have a question about R CMD COMPILE. As I can see, when the package's Makefile calls
R CMD COMPILE foo.cpp
Why does your package have a Makefile? And why is it calling COMPILE and not SHLIB?
My package has a Makefile because I need to compile 16 .cpp files. After it, I call R CMD SHLIB.
R CMD SHLIB would do that for you. Many packages using multiple .cpp files have no Makefile. Please study the many examples on CRAN.
