README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers,
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.

                Notes on enabling maintainer mode

Note that if you configure with --enable-maintainer-mode, you will need
special versions of automake, autoconf, libtool and gettext. You will
find the sources for these in the respective upstream directories:

  https://ftp.gnu.org/gnu/autoconf
  https://ftp.gnu.org/gnu/automake
  https://ftp.gnu.org/gnu/libtool
  https://ftp.gnu.org/gnu/gettext

The required versions of the tools for this tree are:

  autoconf 2.69
  automake 1.15.1
  libtool 2.2.6
  gettext 0.16.1

Note - "make distclean" does not work with maintainer mode enabled.
The Makefiles in the some of the po/ subdirectories depend upon the
Makefiles in their parent directories, and distclean will delete the
Makefiles in the parent directories before running the Makefiles in
the child directories.  There is no easy way around this (short of
changing the automake macros) as these dependencies need to exist in
order to correctly build the NLS files.

When running the testsuites a minimum version of dejagnu is also needed.
Dejagnu can be found here:

  https://ftp.gnu.org/gnu/dejagnu/

The minimum version required is:

  dejagnu 1.5.3
