This is an appendix to Understanding Unix/Linux Programming written for people interested in Ada programming on POSIX systems.

Understanding Unix/Linux Programming

A Guide to Theory and Practice

You may want to download the Ada version of the examples from the book.

For each chapter there is source code for the examples, and a make file with the preferred compiler flags for each example.

These appendices to Understanding Unix/Linux Programming assume that you are using the GNU Ada compiler (GNAT). If you run Debian or Ubuntu you are advised to install these packages:

ada-mode

ada-reference-manual

build-essential

emacs

gnat

gnat-doc

libflorist-dev

manpages-dev

libncurses5-dev

The packages can be installed using this command:

% sudo aptitude install ada-mode ada-reference-manual build-essential emacs gnat gnat-doc libflorist-dev manpages-dev libncurses5-dev

Please make sure that you have this alias set up before you start:

% alias gnatmake='gnatmake -gnat05 -gnatE -gnato -gnatv -gnati1 -gnatf -fstack-check -m -O3'

You can check if it is set correctly like this:

% alias gnatmake gnatmake='gnatmake -gnat05 -gnatE -gnato -gnatv -gnati1 -gnatf -fstack-check -m -O3' %

When you have added this to your shell profile, gnatmake will automatically have the appropriate settings for compiling the examples included with this text.

Ada Distilled is a useful (and free) introduction to Ada for people already familiar with programming in other languages. You can also download the examples from Ada Distilled .

Another option for studying Ada is John Barnes' Programming in Ada 2005 .
