Hi, all

I am in the process of writing my first R extesion package.

One of my function uses StrToInternal function(I copy it from other extension package). I noticed the StrToInternal was defined in "Defn.h". I have two questions:
1)should "Defn.h" be under $R_HOME/include. I could not find it in any file under $R_HOME/include.
2)Where is the implementation for the functions defined in the "Defn.h"? Where dynamic library should I link to for the StrToInternal implementation?

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 package is compiled during installation like this
