R devel - Oct 2014 - How can I use R-function in My C++ project ?

Dear seniors:
   I am a student in Nanjing Agricultural University of China.


   I want to use the  function "optim"  of package stats in my C++
project. I have got the R.dll , R.def and R.lib,


but I can't find the function prototypes of "optim" in R.def. 
  
   How  can  I  do ?  Is the Method I call R function in C++ with R.dll feasible
?  I hope to get your help ! Thanks


for reading my question.


Yours sincerely,


Bo Huang

See section 6.8, "Optimization", in the Writing R Extensions manual.  
I
believe these functions require all of R, not just the Rmath library 
documented in the previous section.  If you want your C++ project to be 
in control, it will need to act as a "front-end", documented in
Chapter 8.
