[Rcpp-devel] Compile errors when including Rcpp 0.11

Hi Jonathon,

| We've been using Rcpp in a project for some time now, and have found
| it invaluable. However, we've just updated to 0.11 and when we try and

[ Releases have standard triple-version names, so it is 0.11.0 right now. ]

| compile our project including the Rcpp header files, we get errors
| (seems to work fine under clang++ on OSX). We're building using the
| Rtools tools.
| 
| it errors on line 22 of PreserveStorage.h :
| 
| static_cast<CLASS&>(*this).update(data) ;
| 
| with the error:
| 
| 'class Rcpp::InternalFunction_Impl<Rcpp::PreserveStorage>' has no
| member named 'update'

That sounds suspiciously like something Kevin fixed shortly after the
release.  

Could you try the version in the GitHub repo at 

   https://github.com/RcppCore/Rcpp

and see if that works?

Thanks,  Dirk

Hi Dirk,

Thanks for your speedy response.

That sounds suspiciously like something Kevin fixed shortly after 
the release.

Could you try the version in the GitHub repo at

https://github.com/RcppCore/Rcpp

and see if that works?

It didn't work, I get the same error.

I installed from github using:

install_github("RcppCore/Rcpp")

this updated my Rcpp to version 0.11.0.2

but the problem persists.

Any further suggestions?

with thanks

Not really.  A minimal reproducible example would help.  

The corpus of now 180 packages at CRAN work across OS X, Windows and Linux;
as do 19 BioC packages in the next release plus an unknowable number of
private packages.

But there can always be fresh bugs in unseen code. But to fix something, it
helps tremendously to be able to reproduce it.  

Can you assist with a small example?

Dirk
