[Rcpp-devel] Cannot find header file R.h in Rcpp c++ package

[Mingyu Tang]

Hi Dirk,

Thanks for your reply.
I am new hand on this and got a little confused.
So instead of using 'g++' , I should use 'R CMD SHLIB' to compile my c++ code, right?

Could you complete the command in the command line? For example, let's say, my c++ file is 'example.cpp'. Shall I input  'R CMD SHLIB example.cpp' ? which flag shall I use to indicate where the Rcpp package is?

Thank you very much.

Mingyu
