[Rcpp-devel] (OS X / 64 bit woes?) R CMD check failing on skeletonc Rcpp module

[Davor Cubranic]

Bob, which version of OS X and g++ do you have? 

I had no problems running your example on Lion. But with that release
I had to install Rcpp from source, while your transcript indicates a
binary version of the package was installed, so you must be using
either Leopard or Snow Leopard.

The version of g++ is also important. I wonder why we see the
following line in the log:
ld: warning: in /usr/local/lib/libstdc++.dylib, file was built for 
unsupported file format which is not the architecture being linked (i386)

I doubt that's the cause of the crash, because the loading fails for
you for the 64-bit version of the package, not 32-bit, but still,
something is off with your toolchain.

The problem with XCode is that release 4, which you need with Mac
Lion, is only available through the App store. It also does not
include GCC but llvm-gcc, which some people have had problems with.
It's easiest to just go with the GCC that the R team makes available
at http://r.research.att.com/tools/
