On Win32, the default cross-compilation host is SBCL with a --sysinit NUL --userinit NUL. Unfortunately, SBCL itself doesn't recognize NUL as a valid filename as it's actually a DOS device name and there's a separate API to check for them. The least losing workaround is to use a real file with known-harmless content for userinit and sysinit, and the simplest choice is version.lisp-expr. This changes makes it possible to build on Win32 without specifying a host lisp.

# The value of SBCL_XC_HOST 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. Some suitable values are:
|
|
# "sbcl" to use an existing SBCL binary as a cross-compilation host
|
|
# "sbcl --sysinit /dev/null --userinit /dev/null"
|
|
# to 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
|
|
# "sbcl --disable-debugger"
|
|
# to use an existing SBCL binary as a cross-compilation host
|
|
# and tell it to handle errors as best it can by itself
|
|
# (probably by dying with an error code) instead of waiting
|
|
# endlessly for a programmer to help it out with input
|
|
# on *DEBUG-IO*
|
|
# "lisp -batch" to use an existing CMU CL binary as a cross-compilation host
|
|
# "lisp -noinit -batch"
|
|
# to use an existing CMU CL binary as a cross-compilation host
|
|
# when you have weird things in your .cmucl-init file
|
|
# "openmcl --batch"
|
|
# to use an OpenMCL binary as a cross-compilation host
|
|
# "clisp"
|
|
# to use a CLISP binary as a cross-compilation host
|
|
#
|
|
# FIXME: Make a more sophisticated command line parser, probably
|
|
# accepting "sh make.sh --xc-host foolisp" instead of the
|
|
# the present "sh make.sh foolisp".
|
|
# FIXME: Tweak this script, and the rest of the system, to support
|
|
# a second bootstrapping pass in which the cross-compilation host is
|
|
# known to be SBCL itself, so that the cross-compiler can do some
|
|
# optimizations (especially specializable arrays) that it doesn't
|
|
# know how to implement how in a portable way. (Or maybe that wouldn't
|
|
# require a second pass, just testing at build-the-cross-compiler time
|
|
# whether the cross-compilation host returns suitable values from
|
|
# UPGRADED-ARRAY-ELEMENT-TYPE?)
