Hello all,
I'm using Rstudio 0.97.306, R 2.15-2, and Rcpp 0.10.2 with Windows 7 Professional x64. I recently switched to using the build tool in Rstudio, however, my generated file RcppExports.cpp and RcppExports.R are checked into version control, so they are read-only. The build fails with *************** ==> Rcpp::compileAttributes() Error in eval(expr, envir, enclos) : file io error: 'C:/Foundation/Common/RiskFinancialLibrary/Prototypes/FiservPrototypes/s rc/RcppExports.cpp' Calls: source ... withVisible -> eval -> eval -> <Anonymous> -> .Call Execution halted *************** I have them checked in as I need to modify RcppExports.cpp manually, after running compileAttributes(), to avoid compiling in Visual Studio (see below for explanation, if you are interested): #ifndef _MSC_VER #include <Rcpp.h> using namespace Rcpp; ... #endif I tried removing the generated key at the top of RcppExports.cpp since this is mentioned in the Rcpp Attributes Vignette. However, I still have the error. Perhaps I've misinterpreted section 3.5.2 "Generated Code"? In order to avoid generating traffic on the list let me comment on why I'm wrapping RcppExports.cpp with _MSC_VER. My employer produces all applications and libraries in Visual Studio. I wrap my ANSI C++ classes with .NET managed C++ classes and build a .NET assembly. This allows me to use Rcpp to test my C++ implementations of models against a clean implementation in R and fulfill company requirements that I use Visual Studio unit tests for quality assurance. I can then deliver the assembly build to developers for use in their own projects. I may turn the previous paragraph into a presentation for the Atlanta R User's Group.
