[Rcpp-devel] Compile problem on Win x64 resolved with -std=c++0x

[Smith, Dale]

Hi all,

I had the "long long unsigned int" problem today on Win x64. I passed
--no-multiarch to R CMD build after making a package using
Rcpp.package.skeleton. The error message in part was

***
C:/R/R-2.15.1/library/Rcpp/include/Rcpp/internal/wrap.h:433:11: error:
invalid conversion from 'long long unsigned int' to 'SEXP'
[-fpermissive]
make: *** [stdVector.o] Error 1
***

I resolved the problem using

PKG_CXXFLAGS = "-std=c++0x"

in my Makevars files.

gcc 4.6.3 (from Rtools215) apparently doesn't support "c++11". Based on
the list traffic I've seen, I suspect c++0x is not supported by CRAN,
but I haven't looked into it, so YMMV.
