Install multiple versions of Rtools
Got it, thanks much! I missed the important detail that $win expands only later. Perfect. Gabor

The $(WIN) within the BINPREF is automatically expanded to the correct architecture. This is definitely possible as we have it working currently in Rcpp, devtools, and RStudio. On Sat, Oct 1, 2016 at 8:29 PM, JJ Allaire <jj.allaire at gmail.com> wrote:
You can do the following: 1) Add the Rtools bin directory (e.g. C:\Rtools33\bin) to the PATH (so it can find make, etc.) 2) Define BINPREF environment variables as seen here: https://github.com/RcppCore/Rcpp/blob/master/R/Attributes.R#L766-L767 Note that creating a valid path to the root Rtools directory is a bit finicky so we have this helper function: https://github.com/R cppCore/Rcpp/blob/master/R/Attributes.R#L780-L790. Here's a C++ version of the same function that we use in RStudio: https://github.com/rs tudio/rstudio/blob/db703b6aff4f4136532e99bb1f2c081fe77f5601/ src/cpp/core/r_util/RToolsInfo.cpp#L39-L46 On Sat, Oct 1, 2016 at 8:06 PM, G?bor Cs?rdi <csardi.gabor at gmail.com> wrote:
Hi All, I would like to have both rtools 3.3 and 3.4 on the same machine, one in c:\rtools33, the other in c:\rtools34. I managed to do it via modifying the RHOME/etc/ARCH/Makeconf files. Is there a better way, by simply setting environment variables? Thanks much! Gabor
