[Rcpp-devel] Attribute does not compile with 'compileAttributes' but with 'sourceCpp'

[JJ Allaire]

Simon,

The other use was also using gcc-4.8.1 so it's got something to do with
that (I don't have a local install of gcc-4.8.1 so can't repo offhand). If
you are running compileAttributes inside RStudio it will run in a separate
process. If not then I don't know of any significant difference between
calling sourceCpp and compileAttributes.
