- This is a beta release of a completely rewritten binutils distribution.
- (Rewritten since binutils 1.x, that is.)
-
- The linker (ld) has been moved into a separate directory, which should be
- ../ld. Linker-specific notes are in ../ld/README.
-
- As of version 2.5, the assembler (as) is also included in this package, in
- ../gas. Assembler-specific notes can be found in ../gas/README.
-
- These programs have been tested on various architectures.
- 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, ../ld/NEWS, and ../gas/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-2.5 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-2.5.tar.gz file, you'll get a directory
- called something like `binutils-2.5', which contains:
-
- COPYING bfd/ configure* libiberty/
- COPYING.LIB binutils/ configure.in move-if-change*
- CYGNUS build-all.mk etc/ opcodes/
- ChangeLog config/ gprof/ test-build.mk
- Makefile.in config.guess* inc
-
- To build binutils, you can just do:
-
- cd binutils-2.5
- ./configure [ --enable-targets='target1,target2...' ]
- make
- make install # copies the programs files into /usr/local/bin
- # by default.
-
- This will configure and build all the libraries as well as binutils
- and the linker.
-
- The --enable-targets option adds support for more binary file
- formats besides the default. By default, support for only the
- selected target file format is compiled in. To add support for more
- formats, 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 (this was
- the default in previous releases):
-
- ./configure --enable-targets=all
-
- The binutils can be used in a cross-development environment.
- The file etc/configure.texi contains more information.
-
- Porting
- =======
- Binutils-2.5 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
- raeburn@cygnus.com or ian@cygnus.com.
