In order to build GNAT, the Ada compiler, you need a working GNAT
compiler (GNAT version 3.14 or later, or GCC version 3.1 or later),
including GNAT tools such as @command{gnatmake} and @command{gnatlink},
since the Ada front end is written in Ada (with some
GNAT-specific extensions), and GNU make.
However, you do not need a full installation of GNAT, just the GNAT
binary @file{gnat1}, a copy of @file{gnatbind}, and a compiler driver
which can deal with Ada input (by invoking the @file{gnat1} binary).
Of course, you still need a working C compiler, with the same compiler
driver.
@command{configure} does not test whether the GNAT installation works
and has a sufficiently recent version; if too old a GNAT version is
installed, the build will fail unless @option{--enable-languages} is
used to disable building the Ada front end.
Additional build tools (such as @command{gnatmake}) or a working GNAT
run-time library installation are usually @emph{not} required. However,
if you want to bootstrap the compiler using a minimal version of GNAT,
you have to issue the following commands before invoking @samp{make
bootstrap} (this assumes that you start with an unmodified and consistent
source distribution):
@example
cd @var{srcdir}/gcc/ada
touch treeprs.ads [es]info.h nmake.ad[bs]
@end example
At the moment, the GNAT library and several tools for GNAT are not built
by @samp{make bootstrap}. For a native build, you have to invoke
@samp{make gnatlib_and_tools} in the @file{@var{objdir}/gcc}
