Hi,
Yes, the problem is with spaces in path names. This has
been fixed and
will appear as Rcpp 0.7.8 in a few days.
If you are in a rush, you can build it from svn, or quote
the path that
is returned from CxxFlags.
Feel free to get back to us with more questions, although
I'd encourage
you to use the dedicated Rcpp-devel mailing list :
https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel

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 sucessfully 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
-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
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

I think the first question should be how to build
a R function to call a bunch of C ,C++ which include one
main program, and a makefile. My goal to build a R package
will be next step.
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.
I read Rcpp , I am not sure ifÂ
RcppResultSet can solve my problem or other function. Once I
make sure it work I need ask UNIX adminstrator to install
it.
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 think it shouldn't be very complex, as I
know to build a R function easy with one C function.
Thanks you for yout attention!

Now, can you let us know
   a) what part of the
answer was unclear to you, and
   b) what made you think
you needed to repost _the identical question_ here
| Thank you in advance!
You're welcome.
