Building a DLL From a Single Source File
The single source file from which you build the DLL can contain one or more source programs.
You can build a DLL from a single source file in either one step or two: either compile the source
file and have the compiler call the linker, or compile the source file and call the linker yourself.
(For linker instructions, see the eld Manual.)

Compile the source file with these directives:
• SHARED (page 568)
• RUNNABLE (page 562)
• ELD (page 548) with either of these options:
-export_all, which exports all program names in the source file◦
◦ -export program-name, which exports only the specified program name. You must
repeat this option for every program name that you want to export.
The resulting loadfile is a DLL.
The command in Example 163 compiles the source file LIB1 and links the resulting object file,
creating a DLL named MYDLL.
