[Rcpp-devel] Package built with Rcpp fails to install

Le 3 f?vr. 2014 ? 20:35, Tal Galili <tal.galili at gmail.com> a ?crit :

Dear all,

Dirk -
I have now re-checked, and the package loads fine on my machine, and it is
completely synced with github.
The only files in my gitignore are:
.Rproj.user
.Rhistory
.RData
src/*.o
src/*.so
src/*.dll
So I suspect that the versions are indeed the same.

Kevin - thanks.

Romain -
I am glad you have an idea for what the problem might be. However, I am not
sure I understand how to proceed in fixing it.


Since the package is very minimalistic, any specific examples on what can be
improved would be of great help.


My message was more or less aimee at kevin who volunteered to help you. I
juqt wanted to give him some context. I'm sure kevin will be able to make
sense of why i said.

Otherwise i'll have a look, but not this week.

Cheers,

Romain



Thanks everyone,
Tal

The problem is likely to be that it was assumed that List derives from
RObject.

It used to, it does not anymore.

Classes from the api now use a policy based design. See andrei
alexandrescu's modern c++ book for the why and the how of policy based
design.

Hi Tal,

I get the same error with the new CRAN Rcpp, 0.11.0. I'll try to take
a look later.

Dear Rcpp people,

I am trying to get a new package to CRAN called {dendextendRcpp}. Here
is
the repos:
https://github.com/talgalili/dendextendRcpp

(note that this package relies on the {dendextend} which has just been
released to CRAN today :) )


The package loads fine for me (on R-devel, with Windows 7), however
Kurt
Hornik (CRAN maintainer) could not get the package to load on Linux.
Following is the error massage that he got. Any input (either here or
on the
git repo) will be most appreciated.

With regards,
Tal

========================

(p.s: I suspect this might be because I use .hpp files in src. Should I
use
something else?)
