[Rcpp-devel] RcppArmadillo error

[Abhisek]

Hi,

Ive been trying to make RcppArmadillo work using the example file (fastLM).
I copied and pasted the code and saved it as RcppArmadilloEg.cpp (not to use
fastLM but to figure out how to work RcppArmadillo).  Then i tried using the
command R CMD SHLIB RcppArmadilloEg.cpp but an error came up saying that
RcppArmadillo.h not found.

So i tried doing a symbolic link from /usr/local/include to the directory
where RcppArmadillo.h and RcppArmadilloDefines.h is stored.  I also did a
symbolic link analogously for RcppArmadillo.so.  When i ran R CMD SHLIB
again I got the following error:

abhisek at shieks:~/Desktop/Personal/Test$ R CMD SHLIB RcppArmadilloEg.cpp

-I/home/abhisek/R/i486-pc-linux-gnu-library/2.10/Rcpp/lib -fpic  -g -O2 -c

could someone provide some advice?

Many thanks!
