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
