[Rcpp-devel] sourceCpp and #include .hpp ?

[Kevin Ushey]

Hi Tal,

If you run sourceCpp(..., verbose=TRUE), you'll see that the source code is
copied into a temporary directory, and then the working directory is reset
to that directory. So the header file is no longer discovered there. (not
to mention, you would have to tell sourceCpp where to find those function
definitions that have been included as well... building a package does that
behind the scenes for you)

I think you should stay with recompiling the package, rather than switching
to sourceCpp, when debugging a package.
