		README for BINUTILS

These are the GNU binutils.  These are utilities of use when dealing
with binary files, either object files or executables.  These tools
consist of the linker (ld), the assembler (gas), and the profiler
(gprof) each of which have their own sub-directory named after them.
There is also a collection of other binary tools, including the
disassembler (objdump) in this directory.  These tools make use of a
pair of libraries (bfd and opcodes) and a common set of header files
(include).

There are README and NEWS files in most of the program sub-directories
which give more information about those specific programs.


Unpacking and Installation -- quick overview
============================================

When you unpack the binutils archive file, you will get a directory
called something like `binutils-XXX', where XXX is the number of the
release.  (Probably 2.13 or higher).  This directory contains
various files and sub-directories.  Most of the files in the top
directory are for information and for configuration.  The actual
source code is in sub-directories.

To build binutils, you can just do:

	cd binutils-XXX
	./configure [options]
	make
	make install # copies the programs files into /usr/local/bin
		     # by default.

This will configure and build all the libraries as well as the
assembler, the binutils, and the linker.

If you have GNU make, we recommend building in a different directory:

	mkdir objdir
	cd objdir
	../binutils-XXX/configure [options]
	make
	make install

This relies on the VPATH feature of GNU make.

By default, the binutils will be configured to support the system on
which they are built.  When doing cross development, use the --target
configure option to specify a different target, eg:

	./configure --target=foo-elf        

The --enable-targets option adds support for more binary file formats
besides the default.  List them as the argument to --enable-targets,
separated by commas.  For example:

	./configure --enable-targets=sun3,rs6000-aix,decstation

The name 'all' compiles in support for all valid BFD targets:

	./configure --enable-targets=all

On 32-bit hosts though, this support will be restricted to 32-bit
target unless the --enable-64-bit-bfd option is also used:

	./configure --enable-64-bit-bfd --enable-targets=all
	
You can also specify the --enable-shared option when you run
configure.  This will build the BFD and opcodes libraries as shared
libraries.  You can use arguments with the --enable-shared option to
indicate that only certain libraries should be built shared; for
example, --enable-shared=bfd.  The only potential shared libraries in
a binutils release are bfd and opcodes.

The binutils will be linked against the shared libraries.  The build
step will attempt to place the correct library in the run-time search
path for the binaries.  However, in some cases, after you install the
binaries, you may have to set an environment variable, normally
LD_LIBRARY_PATH, so that the system can find the installed libbfd
shared library.

To build under openVMS/AXP, see the file makefile.vms in the top level
directory.


Native Language Support
=======================

By default Native Language Support will be enabled for binutils.  On
some systems however this support is not present and can lead to error
messages such as "undefined reference to `libintl_gettext'" when
building there tools.  If that happens the NLS support can be disabled
by adding the --disable-nls switch to the configure line like this:

	../binutils-XXX/configure --disable-nls


If you don't have ar
====================

If your system does not already have an 'ar' program, the normal
binutils build process will not work.  In this case, run configure as
usual.  Before running make, run this script:

#!/bin/sh
MAKE_PROG="${MAKE-make}"
MAKE="${MAKE_PROG} AR=true LINK=true"
export MAKE
${MAKE} $* all-libiberty
${MAKE} $* all-intl
${MAKE} $* all-bfd
cd binutils
MAKE="${MAKE_PROG}"
export MAKE
${MAKE} $* ar_DEPENDENCIES= ar_LDADD='../bfd/*.o ../libiberty/*.o `if test -f ../intl/gettext.o; then echo '../intl/*.o'; fi`' ar

This script will build an ar program in binutils/ar.  Move binutils/ar
into a directory on your PATH.  After doing this, you can run make as
usual to build the complete binutils distribution.  You do not need
the ranlib program in order to build the distribution.

Porting
=======

Binutils-2.13 supports many different architectures, but there
are many more not supported, including some that were supported
by earlier versions.  We are hoping for volunteers to improve this
situation.

The major effort in porting binutils to a new host and/or target
architecture involves the BFD library.  There is some documentation
in ../bfd/doc.  The file ../gdb/doc/gdbint.texinfo (distributed
with gdb-5.x) may also be of help.

Reporting bugs
==============

Send bug reports and patches to:

   bug-binutils@gnu.org.

Always mention the version number you are running; this is printed by
running any of the binutils with the --version option.  We appreciate
reports about bugs, but we do not promise to fix them.

VMS
===

This section was written by Klaus K"ampf <kkaempf@rmi.de>.  It
describes how to build and install the binutils on openVMS (Alpha and
Vax).  (The BFD library only supports reading Vax object files.)

Compiling the release:

To compile the gnu binary utilities and the gnu assembler, you'll
need DEC C or GNU C for openVMS/Alpha. You'll need *both* compilers
on openVMS/Vax.

Compiling with either DEC C or GNU C works on openVMS/Alpha only. Some
of the opcodes and binutils files trap a bug in the DEC C optimizer,
so these files must be compiled with /noopt.

Compiling on openVMS/Vax is a bit complicated, as the bfd library traps
a bug in GNU C and the gnu assembler a bug in (my version of) DEC C.

I never tried compiling with VAX C.


You further need GNU Make Version 3.76 or later. This is available
at ftp.progis.de or any GNU archive site. The makefiles assume that
gmake starts gnu make as a foreign command.

If you're compiling with DEC C or VAX C, you must run

  $ @setup

before starting gnu-make. This isn't needed with GNU C.

On the Alpha you can choose the compiler by editing the toplevel
makefile.vms. Either select CC=cc (for DEC C) or CC=gcc (for GNU C)


Installing the release

Provided that your directory setup conforms to the GNU on openVMS
standard, you already have a concealed device named 'GNU_ROOT'.
In this case, a simple

 $ gmake install

suffices to copy all programs and libraries to the proper directories.

Define the programs as foreign commands by adding these lines to your
login.com:

  $ gas :== $GNU_ROOT:[bin]as.exe
  $ size :== $GNU_ROOT:[bin]size.exe
  $ nm :== $GNU_ROOT:[bin]nm.exe
  $ objdump :== $GNU_ROOT:[bin]objdump.exe
  $ strings :== $GNU_ROOT:[bin]strings.exe

If you have a different directory setup, copy the binary utilities
([.binutils]size.exe, [.binutils]nm.exe, [.binutils]objdump.exe,
and [.binutils]strings.exe) and the gnu assembler and preprocessor
([.gas]as.exe and [.gas]gasp.exe]) to a directory of your choice
and define all programs as foreign commands.


If you're satisfied with the compilation, you may want to remove
unneeded objects and libraries:

  $ gmake clean
