# "When we build software, it's a good idea to have a reliable method

# starting from the same source to end up in the same result. That's
# just a basic intellectual premise."

# $DEVNULL, but that doesn't work on Win32 because SBCL doesn't handle
# device names properly. We still need $DEVNULL to be NUL on Win32
# because it's used elsewhere (such as canonicalize-whitespace), so we
# need an alternate solution for the init file overrides. --no-foos
# have now been available long enough that this should not stop anyone

\`make.sh' drives the SBCL build.
Usage: $0 [OPTION]...
Important: make.sh does not currently control the entirety of the
build: configuration file customize-target-features.lisp and certain
environment variables play a role as well. see file INSTALL for
details.
Options:
-h, --help Display this help and exit.
--prefix=<path> Specify the install location.
Script install.sh installs SBCL under the specified prefix
path: runtime as prefix/bin/sbcl, additional files under
prefix/lib/sbcl, and documentation under prefix/share.
This option also affects the binaries: built-in default for
SBCL_HOME is: prefix/lib/sbcl/
Default prefix is: /usr/local
--dynamic-space-size=<size> Default dynamic-space size for target.
This specifies the default dynamic-space size for the SBCL
being built. If you need to control the dynamic-space size
of the host SBCL, use the --xc-host option.
If not provided, the default is platform-specific. <size> is
taken to be megabytes unless explicitly suffixed with Gb in
order to specify the size in gigabytes.
--xc-host=<string> Specify the Common Lisp compilation host.
The string provided should be a command to invoke the
cross-compilation Lisp system in such a way, that it reads
commands from standard input, and terminates when it reaches end
of file on standard input.
Examples:
"sbcl --disable-debugger --no-sysinit --no-userinit"
Use an existing SBCL binary as a cross-compilation
host even though you have stuff in your
initialization files which makes it behave in such a
non-standard way that it keeps the build from
working. Also disable the debugger instead of
waiting endlessly for a programmer to help it out
with input on *DEBUG-IO*. (This is the default.)
"sbcl"
Use an existing SBCL binary as a cross-compilation
host, including your initialization files and
building with the debugger enabled. Not recommended
for casual users.
"lisp -noinit -batch"
Use an existing CMU CL binary as a cross-compilation
host when you have weird things in your .cmucl-init
file.

# and the make-target-*.sh scripts are run on the target machine. In
# ordinary compilation, we just do these phases consecutively on the
# same machine, but if you wanted to cross-compile from one machine
# which supports Common Lisp to another which does not (yet:-) support
# Common Lisp, you could do something like this:
# Create copies of the source tree on both the host and the target.
# Read the make-config.sh script carefully and emulate it by hand
# on both machines (e.g. creating "target"-named symlinks to
# identify the target architecture).
# On the host system:
# SBCL_XC_HOST=<whatever> sh make-host-1.sh
# Copy src/runtime/genesis/*.h from the host system to the target
# system.
# On the target system:
# sh make-target-1.sh
# Copy src/runtime/sbcl.nm and output/stuff-groveled-from-headers.lisp
# from the target system to the host system.
# On the host system:
# SBCL_XC_HOST=<whatever> sh make-host-2.sh
# Copy output/cold-sbcl.core from the host system to the target system.
# On the target system:
# sh make-target-2.sh
# sh make-target-contrib.sh
# Or, if you can set up the files somewhere shared (with NFS, AFS, or
# whatever) between the host machine and the target machine, the basic
# procedure above should still work, but you can skip the "copy" steps.
