title: windows installation of R package
body: <p>I'm running ubuntu, 64bit. I have this minimal test package
  that i made to learn how to do these things (I'm following this <a href="http://www.google.be/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;ved=0CDUQFjAA&amp;url=http://cran.r-project.org/doc/contrib/Leisch-CreatingPackages.pdf&amp;ei=IOvrUOe3G4rL0AWSjoGADA&amp;usg=AFQjCNHmlajNmMov0zsiVa4dw9iyhupiDQ&amp;sig2=CUYtDZA7v60R5PL9JmikOQ&amp;bvm=bv.1357316858,d.d2k&amp;cad=rja" rel="nofollow">tutorial</a>, except i also have some c code in the package). When i run </p>
  
  <pre><code>R CMD check MySmallPackage
  </code></pre>
  
  <p>on it, it works fine (see below). Then, 
  I run </p>
  
  <pre><code>R CMD build MySmallPackage
  </code></pre>
  
  <p>and it works too (see below). So now, i send 
  the resulting .tar.gz to a friend running win7 64 bit 
  (and 64 bit R), and he gets this error message:</p>
  
  <pre><code>*** arch - i386
  ERROR: compilation failed for package 'MySmallPackage'
  * removing 'C:/Users/ES/Documents/R/win-library/2.15/MySmallPackage'
  Warning in install.packages :

  Warning in install.packages :
    installation of package ‘C:/Users/ES/Downloads/MySmallPackage_0.1.1(1).tar.gz’ had non-zero exit status
  </code></pre>
  
  <p>It's very puzzling. Can anybody point me to what might be causing this problem (i have not used windows in many years but the package installs fine on linux). The error message is a bit cryptic to me.</p>
