This guide assumes a basic familiarity with the Ada 95 language, as
described in the International Standard ANSI/ISO/IEC-8652:1995, January
1995.
-It does not require knowledge of the features introduced by Ada 2005
-or Ada 2012.
Reference manuals for Ada 95, Ada 2005, and Ada 2012 are included in
the GNAT documentation package.

+@section System Requirements
+
+
+Even though any machine can run the GNAT toolset and GNAT Studio IDE, in order
+to get the best experience, we recommend using a machine with as many cores
+as possible since all individual compilations can run in parallel.
+A comfortable setup for a compiler server is a machine with 24 physical cores
+or more, with at least 48 GB of memory (2 GB per core).
+
+For a desktop machine, a minimum of 4 cores is recommended (8 preferred),
+with at least 2GB per core (so 8 to 16GB).
+
+In addition, for running and navigating sources in GNAT Studio smoothly, we
+recommend at least 1.5 GB plus 3 GB of RAM per 1 million source line of code.
+In other words, we recommend at least 3 GB for for 500K lines of code and
+7.5 GB for 2 million lines of code.
+
+Note that using local and fast drives will also make a difference in terms of
+build and link time. Network drives such as NFS, SMB, or worse, configuration
+management filesystems (such as ClearCase dynamic views) should be avoided as
+much as possible and will produce very degraded performance (typically 2 to 3
+times slower than on local fast drives). If such slow drives cannot be avoided
+for accessing the source code, then you should at least configure your project
+file so that the result of the compilation is stored on a drive local to the
+machine performing the run. This can be achieved by setting the @code{Object_Dir}
+project file attribute.

You can override this default file naming convention by use of the
special pragma @code{Source_File_Name} (for further information please
-see @ref{35,,Using Other File Names}).
+see @ref{1c,,Using Other File Names}).
Alternatively, if you want to rename your files according to this default
convention, which is probably more convenient if you will be using GNAT
for all your compilations, then the @code{gnatchop} utility
can be used to generate correctly-named source files
-(see @ref{36,,Renaming Files with gnatchop}).
+(see @ref{1d,,Renaming Files with gnatchop}).
You can compile the program using the following command (@code{$} is used
as the command prompt in the examples in this document):
an 'Ada Library Information' file @code{hello.ali},
which contains additional information used to check
that an Ada program is consistent.
-To build an executable file,
-use @code{gnatbind} to bind the program
-and @code{gnatlink} to link it. The
-argument to both @code{gnatbind} and @code{gnatlink} is the name of the
-@code{ALI} file, but the default extension of @code{.ali} can
-be omitted. This means that in the most common case, the argument
-is simply the name of the main program:
-
-@example
-$ gnatbind hello
-$ gnatlink hello
-@end example
-A simpler method of carrying out these steps is to use @code{gnatmake},
-a master program that invokes all the required
-compilation, binding and linking tools in the correct order. In particular,
-@code{gnatmake} automatically recompiles any sources that have been

-the program, as follows:
-
-@example
-$ gcc -c gmain.adb

-
Note that there is no required order of compilation when using GNAT.
In particular it is perfectly fine to compile the main program first.
Also, it is not necessary to compile package specs in the case where
$ gcc -c greetings.ads -gnatc
@end example
-Although the compilation can be done in separate steps as in the
-above example, in practice it is almost always more convenient
-to use the @code{gnatmake} tool. All you need to know in this case

-@section Using the @code{gnatmake} Utility
-
-
-If you work on a program by compiling single components at a time using
-@code{gcc}, you typically keep track of the units you modify. In order to
-build a consistent system, you compile not only these units, but also any
-units that depend on the units you have modified.
-For example, in the preceding case,
-if you edit @code{gmain.adb}, you only need to recompile that file. But if
-you edit @code{greetings.ads}, you must recompile both
-@code{greetings.adb} and @code{gmain.adb}, because both files contain
-units that depend on @code{greetings.ads}.
-
-@code{gnatbind} will warn you if you forget one of these compilation
-steps, so that it is impossible to generate an inconsistent program as a
-result of forgetting to do a compilation. Nevertheless it is tedious and
-error-prone to keep track of dependencies among units.
-One approach to handle the dependency-bookkeeping is to use a
-makefile. However, makefiles present maintenance problems of their own:
-if the dependencies change as you change the program, you must make
-sure that the makefile is kept up-to-date manually, which is also an
-error-prone process.
-
-The @code{gnatmake} utility takes care of these details automatically.
-Invoke it using either one of the following forms:
-
-@example
-$ gnatmake gmain.adb
-$ gnatmake gmain
-@end example
-
-The argument is the name of the file containing the main program;
-you may omit the extension. @code{gnatmake}
-examines the environment, automatically recompiles any files that need
-recompiling, and binds and links the resulting set of object files,
-generating the executable file, @code{gmain}.
-In a large program, it
-can be extremely helpful to use @code{gnatmake}, because working out by hand
-what needs to be recompiled can be difficult.
-
-Note that @code{gnatmake} takes into account all the Ada rules that
-establish dependencies among units. These include dependencies that result
-from inlining subprogram bodies, and from
-generic instantiation. Unlike some other
-Ada make tools, @code{gnatmake} does not rely on the dependencies that were
-found by the compiler on a previous compilation, which may possibly
-be wrong when sources change. @code{gnatmake} determines the exact set of
-dependencies from scratch each time it is run.
