Hi folks,<div><br></div><div>I bumped into the Google techtalk video on Friday and have been playing around with Rcpp and RcppArmadillo over the weekend. Looks excellent! Thanks for all the work.</div><div><br></div><div>When using RcppArmadillo with VecLib, things work as expected. If I change the BLAS to Goto using the link libRBlas.dylib then I get</div>
<div><br></div><div><div>> <span style="white-space:pre-wrap"> </span>fx <- cxxfunction( signature(x = "integer", y = "numeric" ) , '</div><div>+ <span style="white-space:pre-wrap"> </span>int dim = as<int>( x ) ;</div>

The error for the ATLAS blas is identical. I am using the CRAN binary which allows one to load any BLAS as a shared library.</div>
<div><br></div><div>The fix so far has been to stick to the VecLib BLAS. However, these days, I use either the ATLAS BLAS or the Goto BLAS on R/Mac OS (there have been a few threads on the VecLib BLAS in Mac OS. multithreading on Nehalem is broken in VecLib. found Goto works the best for me.) </div>
<div><br></div><div>Would supporting Goto or ATLAS on Mac OS be a major step, or a simpler matter of changing a dynamic link some where to load the library? Looks like libLFile is not picking up the correct path (VecLib is in the same location as ATLAS and Goto)? Appreciate your thoughts.</div>
