Thank you for your help. So far what I did  on my notebook as follows. My OS is windows7.
 
I downloaded Rcpp windows version, and load library("Rcpp") then.
 
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 sucessfully  without any c++ program before.
4, copy  f1.cpp and all other related cpp and c into /src/
5. Rcmd  build --binary test
 
It showed------
 
making DLL....
gcc -l“C:/PROGRA~2/R/R-210~1.1/include",“C:/PROGRA~2/R/R-210~1.1/bin/Rscript -e' Rcpp:::CxxxFlags<>'` -03 -Wall -std =gnu -999 -c cranbombind.c -o cranbombind.o
 
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
 
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..
 
All I tried are on my own PC at home , I will tryon other  PC in my office.
 
Do you have suggestion?. Thanks,
 
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: 
http://cran.r-project.org/web/packages/Rcpp/vignettes/Rcpp-unitTests.pdf

I tried to build R package which include this C++ program and several other R functions.  These R function here are independent  of c++ code.
