This is a beta release of a completely rewritten binutils distribution.
|
|
The linker (ld) has been moved into a separate directory,
|
|
which should be ../ld. Linker-specific notes are in ../ld/README.
|
|
|
|
These programs have been tested on various architectures.
|
|
Most recently tested are sun3 and sun4s running sunos4,
|
|
as well as Sony News running newsos3.
|
|
However, since this is a beta release taken directly from an
|
|
evolving source tree, there might be some problems. In particular,
|
|
the programs have not been ported to as many machines as the
|
|
old binutils. There are also features of the old versions
|
|
that are missing on the new programs. We would appreciate
|
|
patches to make things run on other machines; especially welcome
|
|
are fixes for what used to work on the old programs!
|
|
(See ./TODO, as well a ../bfd/TODO and ../ld/TODO.)
|
|
|
|
Recent changes are in ./NEWS.

Unpacking and Installation -- quick overview
|
|
==========================
|
|
|
|
In this release, the binary utilities, the linker, the generic GNU include
|
|
files, the BFD ("binary file description") library, gprof, and getopt all
|
|
have directories of their own underneath the binutils-2.1 directory.
|
|
The idea is that a variety of GNU tools can
|
|
share a common copy of these things. Configuration scripts and
|
|
makefiles exist to cruise up and down this directory tree and
|
|
automatically build all the pieces in the right order.
|
|
|
|
When you unpack the binutils-2.1.tar.Z file, you'll get a directory called
|
|
something like `binutils-2.1', which contains:
|
|
|
|
DOC.configure README config/ configure* ld/
|
|
Makefile bfd/ config.status* configure.in libiberty/
|
|
Makefile.in binutils/ config.sub include/ texinfo/
|
|
|
|
To build binutils, you can just do:
|
|
|
|
cd binutils-2.1
|
|
./configure [ --with-minimal-bfd=yes ]
|
|
make
|
|
make install # copies the programs files into /usr/local/bin by default.
|
|
|
|
The --with-minimal-bfd-yes flag is a temporary kludge. Using it makes
|
|
the executables smaller, at the price of only being able to handle
|
|
the default binary file format. A more flexible mechanism is planned.
|
|
|
|
This will configure and build all the libraries as well as binutils
|
|
and the linker.
|
|
|
|
The binutils can be used in a cross-development environment.
|
|
The file DOC.configure contains more information.
|
|
|
|
Porting
|
|
=======
|
|
Binutils-2.1 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-4.x) may also be of help.
|
|
|
|
If your system uses some variant of old-style a.out-format,
|
|
you can start with a copy of bfd/newsos3.c, and edit it to fit.
|
|
(You may also need to tweak bfd/aout-target.h.)
|
|
Alternatively, you could use the host-aout.c target. This is a
|
|
special kludge that only works for native (non-cross) configurations.
|
|
|
|
Reporting bugs
|
|
==============
|
|
If you can't track down a bug and send suggestions/patches
|
|
for fixes, you should probably *not* be using this release.
|
|
We have little time to spend tracking down whatever random bugs you
|
|
may run into (except for configurations that Cygnus supports for
|
|
its customers). The general place to send bug reports or patches
|
|
is to bug-gnu-utils@ai.mit.edu; you can also send them directly to
|
|
bothner@cygnus.com or sac@cygnus.com.
