[Rcpp-devel] failed to compile code on the server with simple operations on matrices with type fmat {RcppArmadillo}

[Yue Li]

Dear List,

I’m having an issue with compiling Rcpp code using ‘fmat’ matrix type on the server (Linux distro:
CentOS release 5.11 (Final)) and wondering if someone has a quick fix.

Basically, the following code works fine on my Macbook (R 3.2) but not on the server (Run/sessionInfo pasted).

Any help would be greatly appreciated!

Many thanks,
Yue


Code (test_fmat.cpp):
// -*- mode: C++; c-indent-level: 4; c-basic-offset: 4; indent-tabs-mode: nil; -*-

// we only include RcppArmadillo.h which pulls Rcpp.h in for us
#include <RcppArmadillo.h>

// [[Rcpp::depends(RcppArmadillo, BH, bigmemory)]]


using namespace Rcpp;
using namespace arma;

// [[Rcpp::export]]
fmat fmatMultiply(fmat x, fmat y)
{
        fmat ans = x * y;
            
        return ans;
}



In R:
> sourceCpp('test_fmat.cpp')
