Sample Session Two

In this session we use the same source code, but compile it as position-independent

code (PIC) and create a DLL.

Display the Program Code

There are no changes to the source code used in Session One.

Compile the Program and Library

We use the same compiler, nmc, but select a new option, call_shared, which

creates position independent code (PIC).

There are three new command line options available at compile time to nmc and

nmcplus:

non_shared

directs the compiler to generate non-shared (not PIC) code. This is the default

call_shared

directs the compiler to generate shared (PIC) code. If the runnable option is

also specified, this causes the creation of a PIC executable file; otherwise it

causes the creation of a PIC -linkable object file

shared

directs the compiler to generate shared PIC and to invoke the linker to create a

PIC library file (a DLL).
