[Rcpp-devel] More Rccp and RccpArmadillo Errors on Mavericks

[Scott Monroe]

This is sort of piggy-backing on the thread with Michael and Romain.

I can't get RccpArmadillo working properly and am looking for suggestions.

I have installed:
R 3.0.2
Xcode 5.0.1 and command line tools
gfortran libs (i.e., gfortran-4.9-bin.tar)
Rcpp package from source (i.e., Rcpp_0.10.6.tgz)
RcppArmadillo package from source (i.e., RcppArmadillo_0.3.920.1.tgz)

below, "rowSums.cpp" contains a function Romain Francis wrote, and can be
seen in the middle of this post:
http://www.mail-archive.com/rcpp-devel@lists.r-forge.r-project.org/msg05742.html

In the R session, I have:

> evalCpp("1+1")
[1] 2

> sourceCpp("rowSums.cpp")
Error in
