[Rcpp-devel] sourceCpp issue: code vs. file

[Kevin Ushey]

Hi Rodney,

I have the same problem as you on Mac OSX.

I'm able to successfully compile the file through sourceCpp if I use a file
extension of .cpp rather than .cxx. Could this somehow be the reason why?
Let me know if that works for you.

-Kevin
