i also have ada mode for emacs and emacs.

How can i compile ada-sources?

Is there a test suite in ada to test the installation of the compiler?

Thanks

Robert

Typically, you use gnatmake. For instance, if you've created a main 
procedure named Hello, in hello.adb, you'd do

gnatmake -gnato -fstack-check hello

This compiles hello.adb and any units it depends on that need compiling, 
then binds and links the executable.

Last I checked the emacs mode for Ada uses an obsolete form of project 
files. There are attempts to remedy this but I have not yet seen the 
results.

As beginner I suggest you try GPS instead (you can still use Emacs for 
editing). For 32 bit Linux you get GPS 3.1.3 from Libre [1] for 64bit 
SuSE Linux there is also GPS 4.0.0 version from the GNU Ada Project [2] 
available.

Best you use "gnat make" (as one word or two words - both works almost 
the same). Jeffrey posted some details. You might also want to read [3].

As it is a make (and not just "gnat compile") it will to all the work 
needed. Later, when you got used to the system you can start using 
project files to fine tune you compilation needs.

> Is there a test suite in ada to test the installation of the compiler?

Yes, it is called the ACATS test - The test should be included in one of 
the source rpm of the gcc tool chain. The GNU Ada project publishes the 
result for the GCC releases [3].

The latest version of ada-mode for Emacs is at 

http://stephe-leake.org/emacs/ada-mode/emacs-ada-mode.html

The manual has been updated, and includes a tutorial of how to compile
simple Ada projects.

Please join the mailing list there as well.

They were never "obsolete"; just "different" :).

Please check

_If_ you like a mouse/menu intensive GUI IDE, then GPS is a reasonable
choice. Eclipse is another reasonable choice. Emacs can do mouse/menu
stuff, but it's not as good at it as GPS, especially on Windows (it is
getting better).

If you prefer a keyboard/command-line oriented IDE, that does LaTeX
and VHDL as well as Ada, then Emacs is an excellent choice.

The latest Emacs ada-mode is intended to be very easy to use for
beginners; I welcome feedback on that issue.

The manual includes a tutorial showing how to compile and run a simple
hello-world program, and demonstrates the handling of compiler error
messages.

Hmm. If you are recommending an IDE, you should say how that IDE
invokes gnatmake.

I don't remember how GPS does it; there is either a button to click or
a menu entry to select.

In Emacs, the keystroke is C-c C-c, corresponding to the Ada menu
entry "Build".

S-F4 to compile current file
F4 to build target(s) of current project

I thought that it is well known that I use Vim and Vim support for Ada is
getting better as well. However, I would not suggest Vim to a complete
beginner as GPS works out of the box without trouble and can generate
project files.
