linking library files under linux

[llee]

I'm trying to create a library and link it into my program. I used gcc to compile a number of c files into object files, and created a .a library file using ar. I then used gcc to create an .so library from these object files.  Can someone give me the command line arguments needed to link either of these libraries with a d program? Can someone tell me what commands are needed to use the definitions provided by these libraries in a d program.
