8.12.4.2 A Simple Example - hello.dll

This section describes a simple walk-through of the process used to build, load, and run a function that is defined in a dynamic library.

First compile this simple "Hello World" source:

    hello.c:

    #include <stdio.h>
    __declspec(dllexport) int start();
    int start()
    {
       printf("Hello World\n");
       return 0;
    }

Then build a dynamic library called hello.dll:

cl6x -mv6400+ hello.c -z --import=printf --dynamic=lib -o hello.dlldl6x.6x -e start

Now, load the dynamic loader using a loader that supports ELF executable object files. Then start the dynamic loader running. When using the reference implementation of the dynamic loader (RIDL), you will see the RIDL prompt come up and then you need to issue the following commands:

RIDL> base_image dl6x.6xRIDL> load hello.dllRIDL> execute

You should see the "Hello World" message displayed and then control will return to the RIDL prompt. To terminate the dynamic loader you can enter the exit command from the RIDL prompt.
