Hi,
first of all thank you, Dirk and Romain, so much for this great library! I was
stunned when I saw the examples.
Hence, I started immediately a quite involved project which interfaces another
library to R via C++. Currently I have the problem that I want to expose a
function from a class which returns a pointer to a class. When exposing via the
class_<A>.method("fun", &A::fun);
mechanism, the compiler fails with a message saying that he cannot wrap the
return type of function fun. The returned object itself is a pointer to another
class B. How to solve this? I tried providing the wrap call with no success.
Here is some code which might not work, but explains more detailed:
class B {};
class A {
public:
B* fun();
};
which gives, when compiled:
/Library/Frameworks/R.framework/Versions/2.13/Resources/library/Rcpp/include/Rcpp/internal/wrap.h:428:
error: cannot convert ‘B* const’ to ‘SEXPREC*’ in initialization
Any ideas how to fix this?
Thanks,
PS: Is there some bug tracking tool? I got some weird problem when the function
wrapped expects a char as input. I fixed it somehow, but I am not sure if it is
the right way...
