[R-pkg-devel] DLL requires the use of native symbols

[Duncan Murdoch]

It appears that you have some uses of .Call() where you are passing a 
character variable as the first argument, instead of registering the 
entry point and passing the variable containing the registration 
information.

 From your second link, it looks like Rcpp has some special way to 
handle entry point registration.  I'm not familiar with that, I use the 
basic way described in Writing R Extensions, section 5.4 "Registering 
native routines".
