undefined reference to RcppArmadillo

I am new to Rcpp. I am seeking help with the following problem. It seems that the RcppArmadillo does not work. Could someone give me some suggestions? Many Thanks!

g++ -m64 -I"D:/R/R-32~1.5/include" -DNDEBUG -I"D:/R/R-3.2.5/library/Rcpp/include" -I"D:/R/R-3.2.5/library/RcppArmadillo/include" -I"D:/R/R-3.2.5/library/RcppProgress/include" -I"D:/R/Rcode/Replicating/src" -I"D:/R/Rcode/Replicating/inst/include" -I"d:/RCompile/r-compiling/local/local323/include" -O2 -Wall -mtune=core2 -c test.cpp -o test.o

That looks like a faily common and obvious error of having forgotten to update src/Makevars, and here src/Makevars.win, to contain

PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)

so that the required LAPACK and BLAS functionality is there.

For what it is worth, this also gets added automagically for you if you choose to start from RcppArmadillo.package.skeleton() as is generally recommended.
