Hi Yuen,

The problem is that you did not specify a main() function in your
program.cpp.

But, from your naming, it appears that you are attempting to make a shared
object library.  You should check the syntax for how to make a shared object
library on your platform.  You might need another switch, such as -shared
(the exact syntax can vary by platform).

HTH,
