From 74ad90692c3f7019aa718b988e47a79d20bea1c9 Mon Sep 17 00:00:00 2001 From: Taylor R Campbell Date: Sat, 5 Oct 2013 18:06:59 +0000 Subject: [PATCH] Separate tools from target in the build. To build a native Scheme, instead of just running `make', you must first run make -f Makefile.boot to get a bootstrap toolchain in boot/, every time you want to use a new compiler or cref or sf or star-parser to compile Scheme. --- src/Makefile.boot.in | 224 +++++++++++++++++++++++++++++++ src/Makefile.in | 310 ++++++++++++++++++++++++++++++------------- src/boot/README | 3 + src/configure.ac | 1 + 4 files changed, 449 insertions(+), 89 deletions(-) create mode 100644 src/Makefile.boot.in create mode 100644 src/boot/README diff --git a/src/Makefile.boot.in b/src/Makefile.boot.in new file mode 100644 index 000000000..c8487beff --- /dev/null +++ b/src/Makefile.boot.in @@ -0,0 +1,224 @@ +# Copyright (C) 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, +# 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, +# 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 +# Massachusetts Institute of Technology +# +# This file is part of MIT/GNU Scheme. +# +# MIT/GNU Scheme is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of the +# License, or (at your option) any later version. +# +# MIT/GNU Scheme is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
