Subject: [Rd] How can I use the function in "Defn.h"?
Message-ID: <435305A7.3030200@bioteam.net>

Hi, all

I am in the process of writing my first R extesion package. My extension 
does not do statistics analysis. It serilizes the call, sends the call 
to remote computer. The remote compuer will evaluate the call and 
returns the result back to client machine. The idea is inspired by the 
taskPR package, which is much more complex than what I want to 
accomplish. I use some code from taskPR.
One of the function uses StrToInternal function(I copy it from taskPR 
package). I noticed the StrToInternal was defined in "Defn.h".

When I load my extension and library, I got this error
-------------------------------
 > library("btRRTest")
Error in dyn.load(x, as.logical(local), as.logical(now)) :
         unable to load shared library 
'/common/apps/lib/R/library/btRRTest/libs/btRRTest.so':
   /common/apps/lib/R/library/btRRTest/libs/btRRTest.so: undefined 
symbol: StrToInternal
Error in library("btRRTest") : .First.lib failed for 'btRRTest'
--------------------------------

My understand is that the "StrToInternal" should be compiled in a shared 
library such as R.so. How can I use this function in my code to avoid 
the "undefined symbol" error?

Thanks
