From 2d29a23f0c62bebe57ae31c22f7e96d8506aa400 Mon Sep 17 00:00:00 2001 From: Thomas Schwinge Date: Tue, 13 Nov 2007 18:14:55 +0100 Subject: Don't *include* the shell scripts, but *link* to them. This is for a reason: I manage them in a RCS and from time to time publish updates.

-
-# Thanks to
-# * Thadeu Lima de Souza Cascardo for updating the instructions about getting
-#   the source code of GCC using the Subversion repositories.
-
-# Prerequisites:
-#
-# A build environment for the system you're running the script on is required,
-# i.e. a C compiler with the basic libraries and `make'.  You might also need
-# `flex' and `bison'.
-
-# Usage:
-#
-# Place `cross-gnu' and `cross-gnu-env' somewhere in `$PATH', e.g. in `~/bin/'.
-
-# Get the source code of the
-
-# * GNU Binutils, , `src/binutils'
-#
-#   $ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/src \
-#       co -r binutils-2_17-branch binutils
-#   $ mv src binutils-2_17-branch

-#   Or fetch a tarball from .
-
-# * GNU Compiler Collection, , `src/gcc'
-#
-#   $ svn co svn://gcc.gnu.org/svn/gcc/branches/BRANCH gcc
-#   $ mv gcc BRANCH
-#
-#   BRANCH is one of `gcc-3_3-branch', `gcc-3_4-branch', `gcc-4_0-branch',
-#   `gcc-4_1-branch' or the tag of a released version like `gcc_3_4_3_release'.
-#   Or fetch a tarball from .
-
-# * GNU C Library, , `src/glibc'
-#
-#   $ cvs -d:pserver:anoncvs@sources.redhat.com:/cvs/glibc \
-#       co -r glibc-2_3-branch glibc
-#   $ mv libc glibc-2_3-branch
-#
-#   Change `glibc-2_3-branch' to `glibc-2_5-branch' to get the glibc 2.5 branch
-#   or omit `-r glibc-2_3-branch' if you want to get the trunk, i.e. the glibc
-#   2.6 branch, but note that building both of them currently won't work
-#   without heavy patching.
-#
-#   Or fetch a tarball from .
-#
-#   If you want to use GCC 4.1 or newer, you'll also need to apply the
-#   following patch, for both glibc-2_3-branch and glibc-2_5-branch:
-#   .
-#
-#   If you use a GNU Make version newer than 3.80, you also need to apply the
-#   following patch to glibc-2_3-branch:

-
-# Unpack the tarballs if you downloaded any.
-
-# Create a directory where the cross build shall take place and `cd' to that
-# directory.  Create a subdirectory `src' and create symbolic links for every
-# of the above packages: from `src/PACKAGE' to where you stored or unpacked it.
-# If you don't intend to build several cross compilers or use the source trees
-# otherwise, you can also directly store the source trees in `src/'.  The
-# source trees can be shared between multiple cross build trees since the
-# package's build systems are supposed not to modify the files in the source
-# trees.  Not all packages adhere to that, but they fail to do so only for
-# pre-processed documentation, etc., as far as I can tell.
-
-# Run
-# $ ROOT=. cross-gnu
-# ... to create the cross build environment in the current directory from the
-# sources in `src/'.
-
-# Later, run
-# $ ROOT=WHERE_THE_ROOT_OF_THE_CROSS_BUILD_TREE_IS; . cross-gnu-env
-# ... to set up `$PATH' (and some other environment variables; have a look at
-# cross-gnu-env), so that you can easily use e.g. the cross compiler running
-# `$TARGET-gcc'.
-
-# Notes:
-
-# You can re-run `cross-gnu' to rebuild the parts of the sources that have
-# changed since the last run.  This might save a lot of time and is especially
-# useful if you aren't working with unpacked tarballs, but on CVS's branches or
-# want to quickly get a new tool chain with patches you applied to the source
-# trees.
-# I would, however, _not_ recommend to use this technique when doing major
-# changes to the source trees, like switching from gcc-3.3 to gcc-3.4.

-# There are several parts marked with `TODO' in this file; feel free to have a
-# look at these issues and send the outcome back to me.
