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 |
||||
|
||||

||||
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. |

# Configure fragment invoked in the post-target section for subdirs |
||||
# wanting multilib support. |
||||
# |
||||
# It is advisable to support a few --enable/--disable options to let the |
||||
# user select which libraries s/he really wants. |
||||
# |
||||
# Subdirectories wishing to use multilib should put the following lines |
||||
# in the "post-target" section of configure.in. |
||||
# |
||||
# if [ "${srcdir}" = "." ] ; then |
||||
# if [ "${with_target_subdir}" != "." ] ; then |
||||
# . ${with_multisrctop}../../config-ml.in |
||||
# else |
||||
# . ${with_multisrctop}../config-ml.in |
||||
# fi |
||||
# else |
||||
# . ${srcdir}/../config-ml.in |
||||
# fi |
||||
# |
||||
# See librx/configure.in in the libg++ distribution for an example of how |
||||
# to handle autoconf'd libraries. |
||||
# |
||||
# Things are complicated because 6 separate cases must be handled: |
||||
# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6. |
||||
# |
||||
# srcdir=. is special. It must handle make programs that don't handle VPATH. |
||||
# To implement this, a symlink tree is built for each library and for each |
||||
# multilib subdir. |
||||
# |
||||
# The build tree is layed out as |
||||
# |
||||
# ./ |
||||
# libg++ |
||||
# newlib |
||||
# m68020/ |
||||
# libg++ |
||||
# newlib |
||||
# m68881/ |
||||
# libg++ |
||||
# newlib |
||||
# |
||||
# The nice feature about this arrangement is that inter-library references |
||||
# in the build tree work without having to care where you are. Note that |
||||
# inter-library references also work in the source tree because symlink trees |
||||
# are built when srcdir=. |
||||
# |
||||
# Unfortunately, trying to access the libraries in the build tree requires |
||||
# the user to manually choose which library to use as GCC won't be able to |
||||
# find the right one. This is viewed as the lesser of two evils. |
||||
# |
||||
# Configure variables: |
||||
# ${with_target_subdir} = "." for native, or ${target_alias} for cross. |
||||
# Set by top level Makefile. |
||||
# ${with_multisrctop} = how many levels of multilibs there are in the source |
||||
# tree. It exists to handle the case of configuring in the source tree: |
||||
# ${srcdir} is not constant. |
||||
# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881). |
||||
# |
||||
# Makefile variables: |
||||
# MULTISRCTOP = number of multilib levels in source tree (+1 if cross) |
||||
# (FIXME: note that this is different than ${with_multisrctop}. Check out.). |
||||
# MULTIBUILDTOP = number of multilib levels in build tree |
||||
# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...) |
||||
# (only defined in each library's main Makefile). |
||||
# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000) |
||||
# (only defined in each multilib subdir). |
||||
|
||||
# FIXME: Multilib is currently disabled by default for everything other than |
||||
# newlib. It is up to each target to turn on multilib support for the other |
||||
# libraries as desired. |
||||
|
||||
# We have to handle being invoked by both Cygnus configure and Autoconf. |
||||
# |
||||
# Cygnus configure incoming variables: |
||||
# srcdir, subdir, host, arguments |
||||
# |
||||
# Autoconf incoming variables: |
||||
# srcdir, host, ac_configure_args |
||||
# |
||||
# We *could* figure srcdir and host out, but we'd have to do work that |
||||
# our caller has already done to figure them out and requiring these two |
||||
# seems reasonable. |
||||
# Note that `host' in this case is GCC's `target'. Target libraries are |

# configured for a particular host. |
