Sorry, I think I read your email the wrong way in my first reply.

| Warning message:

That should be harmless.  You did cut off the messages showing that we DO
added RcppEigen to Imports and LinkingTo.

For the other warning, I see these chiefly as failures of the default
package.skeleton() we wrap around: incomplete help pages etc pp, incomplete
sections in help pages.

The resulted page builds / checks for me (after fixing the one .Rd file's
examples section).

I too find it highly annoying that package.skeleton() creates packages with
so many warnings. It would be worth replacing / enhancing, and if I have time
and nothing more pressing to work on I may.

Right.

| abc_1.0.tar.gz provides a number of easily fixed warnings, and then the
| following of which I fail to understand.
| 
| * checking compiled code ... WARNING
| File ‘/Users/easy-e/Desktop/abc.Rcheck/abc/libs/abc.so’:
|   Found ‘___assert_rtn’, possibly from ‘assert’ (C)
|     Objects: ‘RcppExports.o’, ‘rcppeigen_hello_world.o’

Now that would be a real warning bug, and I don't have it with gcc / g++ 4.8.
 
| A similar problem comes up with the following code as the only file in a

| 
| #include <RcppEigen.h>
| // [[Rcpp::depends(RcppEigen)]]
| // [[Rcpp::export]]
| Rcpp::List len(const Eigen::VectorXd& y) {
|   int n = y.size();
|   return Rcpp::List::create(Rcpp::Named("n") = n);
| }

As I showed you, that too builds without issue for me.
 
| An attempt to learn from other packages ( sparseLTSEigen / lme4) was made, but
| I found no such luck. Please let me know what I can do to help.

I appreciate the offer for help.  Right now I don't have a reproducible
problem for you to work on (apart from creating a new / better
package.skeleton() or a post process for it...)

Cheers, Dirk
