Greetings,
I am trying to integrate some packages of mine so they can share some of
the same C++ functions (not exposed to the R front-end user). Here is my
basic structure of the package I wish to export functions.
Class defined in header (foo.h) complete with all public and private
members.
Members defined in cpp file (foo.cpp).
This is also where I thought I could use the Rcpp::interfaces(cpp) function
generate the header file automatically (as I am not aware of a nice linking
operation between multiple package .so files). So each method is prefixed
with //[[Rcpp::export]] for the package building.
I liked this approach because I wouldn't have to rewrite all my methods to
the header file manually. However, this doesn't appear to be working. I
am getting errors on the first method (I have tried only exporting one
method and I get the same error).
In file included from ../inst/include/gpuR.h:7:0,
from RcppExports.cpp:4:
../inst/include/gpuR_RcppExports.h:28:20: error: expected unqualified-id
before ‘<’ token
inline template<typename T> dynEigenMat<T>::dynEigenMat(SEXP A_) {
^
RcppExports.cpp:3313:1: error: expected ‘;’ at end of input
}
^
RcppExports.cpp:3313:1: error: expected ‘}’ at end of input
Any insight would be appreciated. Not sure if it is a problem with using
the template methods or if this means I simply have a typo somewhere (I
don't think so given that the code works without using the Rcpp interfaces
attribute.
Regards,
Charles
