Hello Everyone, I am trying to generate a C static library(libdeepstate.a) in an Rcpp(inst/include/lib) package using Makevars similar to RInside(generating RInside.so and RInside.a) My static library libdeepstate.a has four compiled c programs [image: image.png]
I saved those files DeepState.c, Log.c,Option.c,Stream.c in inst/include folder and using src/Makevars to compile those *.c files and link the respective object files with the static library as follows: src/Makevars: USERLIBST=libdeepstate.a USERDIR=../inst/lib PKG_CPPFLAGS =-I. -I../inst/include/ PKG_LIBS = all: $(SHLIB) userLibrary SOURCES= ../inst/include/DeepState.c ../inst/include/Log.c ../inst/include/Option.c ../inst/include/Stream.c OBJECTS= $(SOURCES:.c=.o) userLibrary: $(USERLIBST) -@if test ! -e $(USERDIR)$(R_ARCH); then mkdir -p $(USERDIR)$(R_ARCH); fi cp $(USERLIBST) $(USERDIR)$(R_ARCH) rm $(USERLIBST) *$(USERLIBST): $(OBJECTS)$(AR) qc $(USERLIBST) $^* @if test -n "$(RANLIB)"; then $(RANLIB) $(USERLIBST); fi When I install the package I get something like this : *gcc -I"/home/akhila/lib/R/include" -DNDEBUG -I. -I../inst/include/ -I/usr/local/include -fpic -g -O2 -c ../inst/include/DeepState.c -o ../inst/include/DeepState.ogcc -I"/home/akhila/lib/R/include" -DNDEBUG -I. -I../inst/include/ -I/usr/local/include -fpic -g -O2 -c ../inst/include/Log.c -o ../inst/include/Log.ogcc -I"/home/akhila/lib/R/include" -DNDEBUG -I. -I../inst/include/ -I/usr/local/include -fpic -g -O2 -c ../inst/include/Option.c -o ../inst/include/Option.ogcc -I"/home/akhila/lib/R/include" -DNDEBUG -I. -I../inst/include/ -I/usr/local/include -fpic -g -O2 -c ../inst/include/Stream.c -o ../inst/include/Stream.ogcc -shared -L/home/akhila/lib/R/lib -L/usr/local/lib -o testproject.so ../inst/include/DeepState.o ../inst/include/Log.o ../inst/include/Option.o ../inst/include/Stream.o -L/home/akhila/lib/R/lib -lRar qc libdeepstate.a ../inst/include/DeepState.o ../inst/include/Log.o ../inst/include/Option.o ../inst/include/Stream.ocp libdeepstate.a ../inst/lib* *rm libdeepstate.a* The code can be found in GitHub:https://github.com/akhikolla/RcppDeepState/ This Travis build has the complete details of the warnings: https://travis-ci.org/github/akhikolla/RcppDeepState/builds/702470420 But when I check the package I get the following warnings: using devtools::check() *W checking pragmas in C/C++ headers and code ...

It is good practice to register native routines and to disable symbol search.* *Found no calls to: ‘R_registerRoutines’, ‘R_useDynamicSymbols’ - why is this necessary as I am trying to compile some external C files(inst/include/DeepState.c) which are not in src folder* *Compiled code should not call entry points which might terminate R nor write to stdout/stderr instead of to the console, nor use Fortran I/O nor system RNGs. - what does this mean?* how can I solve this issue and get rid of the warning in the R CMD check? Can someone please suggest a way to resolve this? Regards, Akhila Chowdary Kolla
