title: Unable to load the Rcpp Package in Windows Server 2008
body: <p>I have been trying to load the most recent version of the Rcpp package (GIT version XXXX) on a Windows Server 2008 R2 platform.  When I do so I get the following error: </p>
  
  <pre><code>&gt; library(Rcpp)
  Error : .onLoad failed in load Namespace() for 'Rcpp', details:
    call: new_dummyObject(.dummyInstancePointer)
    error: object 'class__dummyInstance' not found
  In addition: Warning message:
  package 'Rcpp' was built under R version 3.0.3
  Error: package or namespace load failed for 'Rcpp'
  </code></pre>
  
  <p>I have discussed this with one of the package authors on <a href="https://github.com/RcppCore/Rcpp/issues/147" rel="nofollow">GitHub</a> and we have determined that it is most likely a local issue.  (That being said after more careful investigation, the problem in that post is not exactly the same as what I am getting) I am able to load the same package using Windows Server 2003 using R version 3.0.1 and 3.0.3.  I am coping portions of the linked post here for convenience.  The procedure that I followed to generate the package was the following:</p>
  
  <ol>
  <li>Downloaded the most recent master code from Github (Should be commit 5b510ed)</li>
  <li>Uncompressed the zip file in a temporary directory and rename 'Rcpp-master' to 'Rcpp'</li>
  <li>Installed Rtools version 3.1</li>
  <li>Ensured that RTools bin and the related gcc bin directory was at the beginning of my path</li>
  <li>Used the command "R CMD BUILD Rcpp" to generate the Rcpp_0.11.1.2.tar.gz file</li>
  <li>Use the command "R CMD INSTALL --build --compile-both Rcpp_0.11.1.2.tar.gz to generate the Rcpp_0.11.1.2.zip</li>
  <li>Copy the resulting zip archive to the Windows Server 2008 machine</li>
  <li>Used the R native install local package to install the Rcpp package</li>
  </ol>
  
  <p>Based on the package authors suggestion, I looked at the .libPaths() output on both the working and the not working R versions.  In both cases the output was exactly the same:</p>
  
  <pre><code>[1] "\\\\vnxserver/home/MYACCT/My Documents/R/win-library/3.0"
  [2] "C:/Program Files/R/R-3.0.2/library"
  </code></pre>
  
  <p>I am really at a loss for what to try next in the debugging chain and I am hopeful that some of the SO community can point me in the right direction.  (That is why I am kind of reposting here).  Any comments are welcome.  </p>
  
  <p>Though I posted it in the paragraph earlier, it might not be clear that the related discussion on GitHub is at <a href="https://github.com/RcppCore/Rcpp/issues/147" rel="nofollow">https://github.com/RcppCore/Rcpp/issues/147</a></p>
