[R] Loading a dynamic library

[Astle, William J]

Hi,

I'm trying to load a .dll library into R 2.1.0 on Windows using the
"dyn.load" function.  The library is compiled with gcc 3.3.3 on cygwin
1.5.16.  

I compile and link:

$ gcc -c myfile.cpp -o myfile.o [HRT]
$ gcc -shared myfile.o -o myfile.dll [HRT]

I then type, in the R console, 

> dynload("myfile.dll")[HRT]

And R hangs. 

Any help appreciated.

Thanks.

Will
