[R] inline error message

[_]

Hi all,
I installed the library inline to my default R-enviroment 
(c:\Programme\R.. )
downloaded and installed RTools from 
http://www.murdoch-sutherland.com/Rtools/
to c:\Rtools.
Path variable is set right (with respect to order) but I get still the 
error message
from my R
Error in compileCode(f, code, language, verbose) :
  Compilation ERROR, function(s)/method(s) not created!

Where is my failure ?

Thank you !
