Hi,
I am trying to compile C++ with R and I am coming up against - what I
believe - is a linker configuration issue.
For example, using has_develop() gives the following message...
has_devel()
I assume you're using the function from devtools.
It tests whether you have your development environment set up correctly
for use with devtools, and this result shows you don't. You might try
using the base R tools (e.g. R CMD SHLIB from the command line) to see
if this is a devtools problem or more basic.
If it's a devtools problem, you should contact the maintainer of that
package.
If it's not just a devtools problem and you still need help, you need to
describe what you did in more detail. What is your PATH? What about
other environment variables? What version of R are you using? What
version of Rtools?

I am running Windows 7 (32-bit), Rtools has been installed and is in my
path (i.e. I can run gcc/g++). The object file (.o) gets created but then
the linking goes awry.
Another thing here is that I do not know where the directory RCompile is as
it appears to be trying to link some 64-bit stuff (i.e. extralibs64).
Any help/thoughts would be fantastic,
Sam
