Cannot compile under Windows and RStudio

[renkun-ken]

#include <Rcpp11>
using namespace Rcpp11;

// [[export]]
IntegerVector foo(){
  IntegerVector test {1, 2, 3} ;
  return test ;
}

In RStudio

library(Rcpp11)
library(attributes)
sourceCpp('test.cpp')

which ends up in error:

Error in inDL(x, as.logical(local), as.logical(now), ...) : 
  unable to load shared object 'C:/Users/Kun/AppData/Local/Temp/Rtmpon1XDW/file99011b92905.dll':
  LoadLibrary failure:  The specified module could not be found.
In addition: Warning message:
running command 'C:/PROGRA~1/R/R-31~1.0/bin/x64/R CMD SHLIB "file99011b92905.cpp"' had status 1 

But the default RCpp template can compile with Rcpp without problem.

#include <Rcpp.h>
using namespace Rcpp;

// Below is a simple example of exporting a C++ function to R. You can
// source this function into an R session using the Rcpp::sourceCpp
// function (or via the Source button on the editor toolbar)

// For more on using Rcpp click the Help button on the editor toolbar

// [[Rcpp::export]]
int timesTwo(int x) {
   return x * 2;
}

What might be the problem here?

Does attributes::sourceCpp( "test.cpp", verbose = TRUE ) give you more information ?

[romainfrancois]

Thanks. This helps. I'll try to reproduce it on my local windows machine today.

[romainfrancois]

I believe this was fixed by this commit in Rcpp11. https://github.com/Rcpp11/Rcpp11/commit/e66445f53409dac13c9af0cf73a481b1742fc716

Please update Rcpp11 and try again.

The problem no longer exists! Thanks!
