Salut Robin,

Welcome, at long last, to rcpp-devel.

| Dear rcpp-devel list, 
| 
| I am encountering 2 different problems with Rcpp modules (which by the way are sooo impressively great !) during the install phase of testmod, 
| 
| ---------1st problem
| while trying to check package testmod (to use module) I got : 
| 
| File 'testmod/R/zzz.R':
|   .onLoad calls:
|     require("methods", character = TRUE, quietly = TRUE)

You need to declare a dependency on the package "methods", just like the
error says.

| Package startup functions should not change the search path.
| See section 'Good practice' in ?.onAttach.
| 
| .onLoad: warning in require("methods", character = TRUE, quietly =
|   TRUE): correspondance partielle d'argument de 'character' par rapport 'character.only'
| 
| (Windows R v2.15.2, last Rtools, ...)
| I'm not really used to all these package stuff and clearly do not understand what's happening. Any solution ?
| 
| Actually I have the same error on another package I just tryied to submitt to CRAN but I guess that this won't be accepted ... 
| 
| 
| -----------2nd problem 
| 
| My package was actually rejected on CRAN because it does not compile on Uwe Ligges's windows system, logs are attached and start like that 
| 
| * installing *source* package 'ConConPiWiFun' ...

Your linling instructions are wrong.

So it looks like you have some fundamental issues here with package
construction.  What I would do is the following:

  a) Either start from scratch (say via rcpp.package.skeleto() with the
     module=TRUE argument) to get a basic package using modules; try to then
     expand that by including your code

  b) Take an existing package from CRAN and examine it; for example my
     RcppCNPy is pretty recent, used modules and is small.

Good luck,  Dirk

|  I do not understand the logs but I know 2 things : 
|           a- It compiles and works properly on my windows system (and on mac and linux actually).  
|           b- I had exactly the same error message 2 days ago while trying to run checks on testmod package and it get sorted when I updated my version of RTools. Is it possible that Uwe Ligges has an outdated version of Rtools ? or do you have any idea of where this can come from ?
