[R-pkg-devel] configure.win for multiple architectures

# 
I am trying to compile a package (using Rcpp) where the libraries needed
for linking (assigned with PKG_LIBS) are in different locations depending
upon the architecture (32 or 64 bit).

In the R-admin documents 6.3.1 Windows (
http://www.hep.by/gnu/r-patched/r-admin/R-admin_36.html) it is stated that
if 'configure.win' does something appropriate for both architectures use
option `--force-biarch`'.

Are there any packages that demonstrate this?

Thanks,
Charles

Maybe you can borrow this short piece from Rblpapi which picks a win32 or a
win64 library path:


  ## Distinguish between 32 and 64 bit windows
  ifeq "$(WIN)" "64"
      FLV = x64
  else
      FLV = i386
  endif

  ## Standard compiler / linker flags including windows flavor
  CXX_STD = CXX11
  PKG_CPPFLAGS = -I../inst/include -I.
  PKG_LIBS = -lblpapi3_${WIN} -L${FLV}


There is more in Makevars.win as this file also downloads a vendor library
(which it puts into that very directory). This is per an agreement with CRAN
as it keeps the (not-FOSS) library outside the package, but permits simple
building.  Our package itself is FOSS, but it depends on this vendor library.

Thanks Dirk,

This appears to work for my purposes.
