Hi,

I am using osx 10.4.11 with R version 2.7.1. I am trying to create a
share lib from a little C code and I am getting some errors, which I
cannot make anything out of. The code written is fine, since I am able
to compile it on a linux elsewhere. Any help would be appreciated.

Here's the error --

My guess would be some 3rd party compilers that don't work properly.
Make sure you're using Xcode 2.4 or higher (2.5 is the current version
for Tiger) and that you don't have any broken compilers (e.g. from
HPC) in /usr/local. If in doubt rename (or delete) /usr/local and try
again.

Cheers,
Simon
