[Rcpp-devel] R - couchbase R client using Rcpp

[amine gassem]

Context:

I develop a new rcouchbase package client for couchbase.
I am following the example of rhiredis<https://github.com/eddelbuettel/rhiredis>
 package.
Including libcouchbase headers using : #include <libcouchbase/couchbase.h>works
fine.

Problem:

dyn.load failed to load symbol due to and undefined symbol: lcb_destroy.
I think this is a link problem because I don't tell Rcpp compiler where/how
to find libcouchebase libs.
Ho can I fix this?

What I have tried:

Should I create configure.in and makvers.in like in this RcppGSL
package<http://dirk.eddelbuettel.com/code/rcpp/RcppGSL.pdf>
?
Reading the vignette I did not see how can I adopt it for my needs.
Also from this vignette
<http://dirk.eddelbuettel.com/code/rcpp/Rcpp-package.pdf> it
looks like this changed with Rcpp release 0.11.0. These files are now
optional.
And also, The rhiredis <https://github.com/eddelbuettel/rhiredis> package don't
provide a configure for autoconf, and I think  it works fine.


Thanks again for your help.
