I'll do that.
I may use JJ's stuff as a starting point as well, but I'll look at the
RInside stuff and drop Peter a line as appropriate.
It may also be worthwhile to talk to the cmake project, and see if
they'd be interested in including whatever we to put together, so that
cmake would by de

That actually looks rather perfect.
Thanks!

I use cmake for all my makefile generation. I realize there are other
good tools out there; cmake meets my needs rather well, and I'm happy
with it.
Most libraries I use in my development (cgal, python, perl, swig,
vtk/itk, etc) are supported by FindXXX.cmake files that make dependency

Since cholmod has specific functions for all the allocation/free tasks
involved in the different data structs, if you're really ambitious, you
could probably create a templated mgr c++ class, where the template args
are the specific memory management functions for the wrapped struct.
Then you
I would create a class that contains a pointer to the c struct.
This obviously leaves the problem of freeing the memory, i.e does the c++
object own the pointer.
Maybe a strategy using some reference counting smart pointer.
In RcppEigen we have not resolved this, we simply exposed a free met

This is more a C++ question than an Rcpp question although, of course, the
application will be through Rcpp.
I want to use C functions defined in the CHOLMOD package using Rcpp. The
arguments to these functions and the returned values are usually pointers
to C structs. There are several such stru
I dont know. This looks like a deeply hidden problem.
Maybe you can enable some rcpp debugging by adding
#define RCPP_DEBUG_LEVEL 1
Before you include Rcpp.h, this will give you verbose output, maybe this will
help locating the issue.

Hi Romain,
Thanks very much. I tried your method. And now the old error has gone,
which is really good for me. But a new error is :
Error in betahat(ker, x, X, y, t, h, m) :
(list) object cannot be coerced to type 'double'
Calls: system.time ... apply -> FUN -> betahat -> .External -> cpp_excepti

Thanks, Dirk, Romain, for your insights.
The problem was the following line in my .bashrc
export PKG_CPPFLAGS='-I/TL/opt/R-2.13.2/library/Rcpp/include'
which included Rcpp 0.9.0 in the compilation, creating the
undefined symbol (since Rcpp 0.10.1 has a different signature for
r_vector_start).
