Subject: [Rd] building a package - shared library loading problem
Message-ID: <op.tywv03zs5hzuc0@quantile.local>

Dear All,
I am trying to write my first R package and I bump into loading shared  
library problem( working on Mac OS X 10.4.10 as well as Linux Ubuntu).
I want to makes use of (incorporate) a shared library matchinglib.so in  
the package. Library was created via R CMD -SHLIB.
Following 'Writing R Extensions' I place matchinglib.so in the 'libs'  
directory and use NAMESPACE file with an entry:
useDynLib(matchinglib)

Now, executing 'R CMD check mypackage' I face the following error on OS X:
-----------------------------------------------------
* checking whether the package can be loaded ... ERROR
Error in library.dynam(lib, package, package.lib) :
         shared library 'matchinglib' not found
Error: package/namespace load failed for 'cheetah'
Execution halted

It looks like this package has a loading problem: see the messages for
details.
----------------------------------------------------
The same problem occurs under Linux.

Shall I specify a direct path to libs or modify NAMESPACE?
