Loading a dynamic library

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,
And R hangs. 

Any help appreciated.

Thanks.

Will

Please use the correct OS's DLLs: Cygwin is another OS hosted on Windows. 
This might work, but it is not as good an idea as using the recommended 
compilers, or indeed any other Windows compiler.

            

      
      
      
    

        
What is `dynload', and what does [HRT] mean?

            

      
      
      
    

        
Are you sure?  It is more likely that your DLL's initialization code 
hangs.
