Hello,
I know how to fix RcppEigen, which I will do once I'm home tomorrow at
best.
The code is using a template that I consider implementation detail in
Rcpp, which apparently I used in RcppEigen as if it was part of the API.
When things like this happen, things like that happen.
If anyone wants to fix it before me, it is essentially just about
removing one template argument from r_vector_start call.

Rcpp 0.10.1 was released yesterday (?). Installing it breaks
RcppEigen and RcppArmadillo (same error message). Reinstalling the
packages fixes RcppArmadillo, but not RcppEigen.
The error I get from compiling RcppEigen (version 0.3.1) is
/hpscc/usr/local/gcc-4.1.2/install/R/R-devel/lib64/R/site-library/Rcpp/include/Rcpp/as.h:55:

ERROR: compilation failed for package ‘RcppEigen’
This translates to the following error when I load the already
installed version of RcppEigen:
library(RcppEigen)
Loading required package: Rcpp
Loading required package: Matrix
Loading required package: lattice
Error in dyn.load(file, DLLpath = DLLpath, ...) :

undefined symbol:

Error: package or namespace load failed for ‘RcppEigen’
I got the same error for RcppArmadillo (0.3.4.4) when doing
library(RcppArmadillo), but this was fixed re-installing the package
(unlike RcppEigen).
This may be something you are aware of. I am mostly using RcppEigen
through a chain of dependencies.
I am on a fairly old system, with GCC 4.2.1 under Redhat Enterprise
Linux version 4. This is for our cluster, so it is not easy for me
to
update.
