[R] Rinternals.h and iostream don't play nice together'

[Faheem Mitha]

Hi,

Consider the following file.

*******************************
foo.cc
*******************************
#include <R.h>
#include <Rinternals.h>
#include <iostream>
*******************************

R CMD SHLIB foo.cc

gives scads of errors. I've use C++ extensively with R before (using C 
linkage) but not with Rinternals.h. I'm puzzled. The errors make no sense 
to me. Am I doing something wrong? Is it impossible to use iostream here 
for some reason?

I'm using Debian Sarge with R 2.0.1 and gcc 3.3.5. Please cc me; I'm not 
subscribed. Thanks in advance.

                                                               Faheem.

R CMD SHLIB foo.cc
g++ -I/usr/lib/R/include     -fPIC  -g -O2 -c foo.cc -o foo.o
