[Rcpp-devel] Compiling RcppArmadillo, SVN version 1919

[Douglas Bates]

I get a compilation error of

g++ -I/usr/share/R/include
-I"/home/bates/R/x86_64-pc-linux-gnu-library/2.11/Rcpp/include"
-I../inst/include -fpic  -g -O3 -pipe -Wall -pedantic -c
RcppArmadillo.cpp -o RcppArmadillo.o

                 from ../inst/include/RcppArmadillo.h:25,
                 from RcppArmadillo.cpp:22:

(This is using r-base in Ubuntu 10.04 x86_64 and the same SVN version of Rcpp.)

It appears to be a name clash.  The include file Rmath.h redefines
ftrunc as Rf_ftrunc.
