Oups I put my answer to your comments in the body of the mail and therefore it is almost invisible.
So I tried to apply your suggestion and I still have the same error Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared object '/home/metienne/R/x86_64-pc-linux-gnu-library/3.1/testCMaes/libs/testCMaes.so': libcmaes.so.0: cannot open shared object file: No such file or directory Error: loading failed I'm absolutely not confortable with this, so I wonder if libcmaes.so.0 should be copied in the testCMaes package installation directory or should testCMaes.so access to it in the standard directory ? Regarding your comment on SystemRequirement, yes I am aware of the drawback of using external code. The libcmaes is distributed under LGPLv3 license, so I guess I should be allowed to internalise the library but ... one step at a time. Anyway, thanks again for your advice. At least the global framework is cleaner. Marie -- http://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org
