I do not consider myself a novice software developer. And yet I still have not exceeded the list of things I can learn "the hard way".

Last month I had chance to learn about the dangers of resolving merge conflicts as well as how important is it to do a …

In this article I will continue to extend the runtime running in the kernel module. We have not touched the kernel module part itself yet, just laying the infrastructure.
The next step is to implement the Image attribute. This requires some work as this attribute is implemented differently for each basic type it can be used on.

In this article I will focus on implementing the secondary stack of the runtime.
Secondary stack is required if we desire functions to return objects of unconstrained types. This in turn required for the 'Image attribute, which is used extensively in the Interfaces.C package.

In the following series of blog posts I will document my attempts to write Linux modules using the Ada language.
In part 1, I will demonstrate how to write in Ada and build a simple "hello world" Linux kernel module.
Additionally, I will introduce a basic customized Ada runtime to support our "hello world" module. This runtime will be extended in subsequent articles in the series.

Ada bindings for X11 were written Intermentics company and sponsored by Ada Joint Program Office (AJPO).

While intemetics has long been gone (looks like the it's domain is owned by L3 now), and AJPO was closed in 1998, the bindings are still around.

The "latest" version can be downloaded from …

One of the first things a new Ada programmer will learn is the ability to define constrained type. Which means that one can restrict the values that can be assigned to a variable of this specific type.

For example:

subtype Positive is Integer range 1 .. Integer'Last;

Being a subtype …
