I am trying to add #include <R.h> to a .c file in one of my package, so I can call error() without a complaint about implicit defined function. The src/ has a Makefile, to build some exec/ files that are needed. Without the include, my Makefile target OBJS = $(SRC:.c=.o) $(PKGNAME).so: $(OBJS) rpcx.h $(R_HOME)/bin/R CMD SHLIB $(OBJS) seems to work fine, and I do not need a target for the .o's, the default works. But when I add the include, the location of R.h does not get passed along. How am I suppose to specify $(R_HOME)lib/R/include so that it gets passed along by R CMD SHLIB ? Paul

(you don't need Makefile to just add targets). But your immediate problem is that you want to use R CMD SHLIB $(SRC) and not $(OBJS), otherwise you'll be missing all C*FLAGS (which includes -I that is needed for the headers) since the compilation will be done by your Makefile and not R.
