Dear list,
Getting back to Rcpp after a several month hiatus, during which I
upgraded to R_2.15.1. Loading modules no longer works.
A simple example, from the docs (Rcpp-modules p6):
In a clean R session:
>require(Rcpp)
>require(inline)
>inc <- '
using namespace Rcpp;
double norm( double x, double y ) {
return sqrt( x*x + y*y );
}
RCPP_MODULE(mod) {
function( "norm", &norm );
}
'
>fx <- cxxfunction(signature(), plugin="Rcpp", include=inc)
Error in dyn.load(libLFile) :
unable to load shared object '/tmp/RtmpbGnBB9/file2eb333e010d3.so':
/tmp/RtmpbGnBB9/file2eb333e010d3.so: undefined symbol:
_ZN4Rcpp8internal14r_vector_startILi14EdEEPT0_P7SEXPREC
What have I forgotten about?
> sessionInfo()
R version 2.15.1 (2012-06-22)
Platform: x86_64-unknown-linux-gnu (64-bit) ...
other attached packages:
[1] inline_0.3.10 Rcpp_0.10.1
Note that the example code still works under R 2.13.2, Rcpp_0.9.10
and inline_0.3.8.
Thanks for the help
