Discussion

from the news pages about how to do organise the calls from C to D.

From NG:digitalmars.D/7361

Define a function called _init(): 

void _init(void)
{
   /* your code */
}

It will be called when the .so is loaded, just like DllMain. There's a _fini() function for unload time. "man dlopen" for details. It works even if you are not doing dynamic loading with dlopen()!

According to the compiler page, DMD can't handle shared libraries. Are you using GDC?

Conclusion

To run D as a dynamic library under Linux it is necessary to use GDC.
