3 # "When we build software, it's a good idea to have a reliable method
4 # for getting an executable from it. We want any two reconstructions
5 # starting from the same source to end up in the same result. That's
6 # just a basic intellectual premise."
7 # -- Christian Queinnec, in _Lisp In Small Pieces_, p. 313
9 # This software is part of the SBCL system. See the README file for
10 # more information.
12 # This software is derived from the CMU CL system, which was
13 # written at Carnegie Mellon University and released into the
14 # public domain. The software is in the public domain and is
15 # provided with absolutely no warranty. See the COPYING and CREDITS
16 # files for more information.
18 # The value of SBCL_XC_HOST should be a command to invoke the
19 # cross-compilation Lisp system in such a way that it reads commands
20 # from standard input, and terminates when it reaches end of file on
21 # standard input. Some suitable values are:
22 # "sbcl" to use an existing SBCL binary as a cross-compilation host
23 # "sbcl --sysinit /dev/null --userinit /dev/null"
24 # to use an existing SBCL binary as a cross-compilation host
25 # even though you have stuff in your initialization files
26 # which makes it behave in such a non-standard way that
27 # it keeps the build from working
28 # "sbcl --disable-debugger"
29 # to use an existing SBCL binary as a cross-compilation host
30 # and tell it to handle errors as best it can by itself
31 # (probably by dying with an error code) instead of waiting
32 # endlessly for a programmer to help it out with input
33 # on *DEBUG-IO*
34 # "lisp -batch" to use an existing CMU CL binary as a cross-compilation host
35 # "lisp -noinit -batch"
36 # to use an existing CMU CL binary as a cross-compilation host
37 # when you have weird things in your .cmucl-init file
38 # "openmcl --batch"
39 # to use an OpenMCL binary as a cross-compilation host
41 # FIXME: Make a more sophisticated command line parser, probably
42 # accepting "sh make.sh --xc-host foolisp" instead of the
43 # the present "sh make.sh foolisp".
44 # FIXME: Tweak this script, and the rest of the system, to support
45 # a second bootstrapping pass in which the cross-compilation host is
46 # known to be SBCL itself, so that the cross-compiler can do some
47 # optimizations (especially specializable arrays) that it doesn't
48 # know how to implement how in a portable way. (Or maybe that wouldn't
49 # require a second pass, just testing at build-the-cross-compiler time
50 # whether the cross-compilation host returns suitable values from
51 # UPGRADED-ARRAY-ELEMENT-TYPE?)
52 # FIXME: --noprogrammer was deprecated in sbcl-0.7.5, replaced by
53 # --disable-debugger. We still use the old form here because the
54 # change was not preannounced, and it would be rude to make our new
55 # version of SBCL unbootstrappable by immediately prior versions.
56 # But in a year or so the --noprogrammer here can change to
57 # --disable-debugger (and the deprecated --noprogrammer support can
58 # go away completely).

63 # If you're cross-compiling, you should probably just walk through the
64 # make-config.sh script by hand doing the right thing on both the host
65 # and target machines.
66 sh make-config.sh || exit 1
68 # The make-host-*.sh scripts are run on the cross-compilation host,
69 # and the make-target-*.sh scripts are run on the target machine. In
70 # ordinary compilation, we just do these phases consecutively on the
71 # same machine, but if you wanted to cross-compile from one machine
72 # which supports Common Lisp to another which does not (yet:-) support
73 # Common Lisp, you could do something like this:
74 # Create copies of the source tree on both the host and the target.
75 # Read the make-config.sh script carefully and emulate it by hand
76 # on both machines (e.g. creating "target"-named symlinks to
77 # identify the target architecture).
78 # On the host system:
79 # SBCL_XC_HOST=<whatever> sh make-host-1.sh
80 # Copy src/runtime/sbcl.h from the host system to the target system.
81 # On the target system:
82 # sh make-target-1.sh
83 # Copy src/runtime/sbcl.nm and output/stuff-groveled-from-headers.lisp
84 # from the target system to the host system.
85 # On the host system:
86 # SBCL_XC_HOST=<whatever> sh make-host-2.sh
87 # Copy output/cold-sbcl.core from the host system to the target system.
88 # On the target system:
89 # sh make-host-2.sh
90 # Or, if you can set up the files somewhere shared (with NFS, AFS, or
91 # whatever) between the host machine and the target machine, the basic
92 # procedure above should still work, but you can skip the "copy" steps.
