If you're on the new Makefile system, you will want to update your Makefile.rules. The patch below provides some important fixes for parallel builds and dependencies. It also adds some new features like the -local targets. For example, you can now build "all-local" to build the local directory without recursing into subdirectories. See the comments below for details of the change.

I've been trying to learn about dynamically loading subroutines in R. Ultimately I would like to use this approach to implement some simulations. For the moment though, I've run into a problem compiling c++ code and loading it into R. The 'C/C++' and 'R'code below works fine when compiled and linked with gcc, but gives an error when the library is compiled and linked with
