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.
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.
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]
What is `dynload', and what does [HRT] mean?
And R hangs.
Are you sure? It is more likely that your DLL's initialization code hangs.
