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

Hi Dominick,

I did install files from brew but instead used the gcc from http://hpc.sourceforge.net

Is there something special I can look for in my Makeconf file? What is so different about ‘compileAttributes’ in contrast to ‘sourceCpp’ or a usual package compilation via R CMD INSTALL? Does compileAttributes uses some additional flags and/or libraries?

I had one other user report this specific error on Mavericks and it seemed to be related to the use of different compilers (and thus different heaps) within the same compilation (there is exposure to this with the changes made by Apple to the toolchain in Mavericks).
