Thank you for your help. So far what I did on my notebook as follows. My OS
is windows7.
Â
I downloaded Rcpp windows version, and load library("Rcpp") then.
Â
1, Change main funnction to f1.cpp, remove makefile.
2 ,run Rcpp.package.skeleton(name="test",list=c("rec1.R","rect2.R"))
3, edit  /man, /R, copied my exist file whch I have done sucessfullyÂ
without any c++ program before.
4, copy f1.cpp and all other related cpp and c into /src/
5. Rcmd build --binary test
Â
It showed------
Â
making DLL....
gcc
-lâC:/PROGRA~2/R/R-210~1.1/include",âC:/PROGRA~2/R/R-210~1.1/bin/Rscript
-e' Rcpp:::CxxxFlags<>'` -03 -Wall -std =gnu -999 -c cranbombind.c -o
cranbombind.o
Â
gcc.exe: **\Documents/R/win-library/2.10/Rcpp/lib: No such file or directory...
I checked the path, it did have C:\Users\alex
**\Documents\R\win-library\2.10\Rcpp\lib
Â
I don't know how I can fix the problem. do you think it could be problem there
is a space between my first name and last name..
Â
All I tried are on my own PC at home , I will tryon other  PC in my office.
Â
Do you have suggestion?. Thanks,
Â
Alex

You should jump straight to making a package. You are making you life
difficult with this "main program & makefile" model.
Install Rcpp and try to use the Rcpp.package.skeleton, this will create
a simple package that uses some C++ classes from Rcpp, as well as an R
function that calls them.

We don't know what your problem is. We can answer a question, but we
cannot guess the question for you.
Rcpp works, please refer to our unit tests, for example look at this
vignette:
