That exposes the data3 class, but does not solve the pointer problem.
Add a default contructor.
This would have been detected at compile time.
Please read the vignette that describes the feature. here is the link:

I updated to the new Rcpp 0.8.9 then added a new function to

It compiles fine the Module is found and loads the class

the class I
get the error:
R> new(Module("GPU_BAYES",'gpuBayes')$data3)
Error in get(".pointer", envir = env) : object '.pointer'
not found
Any Ideas what might be wrong here? That's a rather vague
error. The
traceback gives

3: get(".pointer", envir = env)
2: function (object)
standardGeneric("show")(<S4 object of class "Rcpp_data3">)

Thanks,

In the Rcpp-modules vignette, that has been considerably updated
in the last version of Rcpp (part of the 8661 new lines of
code), we suggest to have this in your .onLoad:
# grab the namespace
NAMESPACE <- environment()
.onLoad <- function(libname, pkgname){
# load the module and store it in our namespace
yada <- Module( "GPU_BAYES" )
populate( yada, NAMESPACE )
}
and the "data3" class is directly exposed in the namespace of
your package, so that you can do:
new( data3 )
Does that work ?
Otherwise, maybe you can try adding mustStart = TRUE to the call
to Module.
