[Rcpp-devel] Error in Building a Package Using Rcpp

[Wonsang You]

Dear Dirk,

Thank you so much for your kind help. I would like to reply to your
questions.

Q1) Did you install Rtools as well?
Of course, I installed Rtools 2.12.

Q2) Have you ever compiled an R package from source on Windows?
Yes. Before compiling the package "mypackage"  in the Windows Command
Prompt, I opened the package from Eclipse as a project, and I ran its R
function in R console as follows.

> Rcpp_hello_world()

But, nothing happened. Thus, I tried to build a package from the skeleton.

Q3) the command you executed
Please, refer to the above answer.

Q4) the errors you got
In the Windows Command Prompt, I had the following error message.

> R CMD build mypackage
checking for file 'mypackage/DESCRIPTION' ... OK
preparing 'mypackage':
checking DESCRIPTION meta-information ... OK
cleaning src
ERROR
copying to build directory failed

Also, a popup window opened with the error message "the operation of
'make.exe' was stopped."
Then, it suggested to refer the following files, but I could not find them
in the specified folder.

\AppData\Local\Temp\WER9159.tmp.WERInternalMetadata.xml
\AppData\Local\Temp\WER9D1D.tmp.appcompat.txt
\AppData\Local\Temp\WERA078.tmp.mdmp

I attached some codes of the package.

-- rcpp_hello_world.R

rcpp_hello_world <- function(){
     .Call("rcpp_hello_world", PACKAGE="mypackage")
}

-- rcpp_hello_world.cpp

#include "rcpp_hello_world.h"

SEXP rcpp_hello_world(){
     using namespace Rcpp;
     CharacterVector x = CharacterVector::create( "foo", "bar" )  ;
     NumericVector y   = NumericVector::create( 0.0, 1.0 ) ;
     List z            = List::create( x, y ) ;
     return z ;
}
