[Rcpp-devel] Problem loading a binary package which links dynamically with Rcpp

[Fabien Ors]

Hi Dirk,

Thank you for your answer. My package is called RGeoS (case sensitive).
Maybe could you try it downloading it from our website ?
http://rgeos.free.fr/forum/viewtopic.php?f=2&t=48

I can reproduce the problem on Ubuntu 12 and Fedora 17 when I install 
Rcpp and RGeoS without root rights (in a directory of mine like 
/home/fors/R-Packs for instance)

What should contain ld.so.conf and how to keep it sync, please ?
Thanks in advance.

Best regards,
