Hi, Sorry - I should have said that I was using Windows 7 on a 64 bit computer in my earlier post.
I used the installer to install R, I did not do a build from source. I have read the installation instructions. Both R and Rtools are first in my path, but by toolchain do you mean that I need to install the mingw-w64 toolchain? Since the installation instructions indicate that Windows 64-bit is integrated into the R package and build systems, I assumed this wasn't necessary - but that would be an easy fix! Thank you. - Katharine 2012/4/14 Uwe Ligges <lig...@statistik.tu-dortmund.de> > > > On 14.04.2012 00:24, Katharine Miller wrote: > >> Hi, >> >> I have some C++ code that I compiled into a dll for use in 32 bit R and >> would like to recompile for use in 64bit R.
