[Rcpp-devel] 64-bit libRcpp.a on 32-bit MacOS

[Davor Cubranic]

Try R CMD INSTALL --help:

      --configure-args=ARGS
                        set arguments for the configure scripts (if any)
      --configure-vars=VARS
                        set variables for the configure scripts (if any)

But why install just this library as 64-bit if the rest of your R installation is 32-bit only?

It's easy to get a multi-architecture (universal) R install: see http://cran.r-project.org/bin/macosx/ for pre-built binaries and http://cran.r-project.org/bin/macosx/RMacOSX-FAQ.html for how to build it from source.
