[Rcpp-devel] Problems getting RInside to work on OS X

[Simon Zehnder]

Thanks Dirk! 

The answers from Romain and you show exactly how to make things work again. I wasn’t aware of the possibility to override the Makeconf via a new Makevars. I work with environment modules to be able to load different compilers and to test my package compilation with them. I can now produce the ~/.R/Makevars file during module load. That makes everything more comfortable than adding a CFLAGS to the R CMD INSTALL command.
