  26 # need an alternate solution for the init file overrides. --no-foos
  27 # have now been available long enough that this should not stop anyone

 133 \`make.sh' drives the SBCL build.
 134
 135 Usage: $0 [OPTION]...
 136
 137   Important: make.sh does not currently control the entirety of the
 138   build: configuration file customize-target-features.lisp and certain
 139   environment variables play a role as well. see file INSTALL for
 140   details.
 141
 142 Options:
 143   -h, --help           Display this help and exit.
 144
 145   --prefix=<path>      Specify the install location.
 146
 147       Script install.sh installs SBCL under the specified prefix
 148       path: runtime as prefix/bin/sbcl, additional files under
 149       prefix/lib/sbcl, and documentation under prefix/share.
 150
 151       This option also affects the binaries: built-in default for
 152       SBCL_HOME is: prefix/lib/sbcl/
 153
 154       Default prefix is: /usr/local
 155
 156   --dynamic-space-size=<size> Default dynamic-space size for target.
 157
 158       This specifies the default dynamic-space size for the SBCL
 159       being built. If you need to control the dynamic-space size
 160       of the host SBCL, use the --xc-host option.
 161
 162       If not provided, the default is platform-specific. <size> is
 163       taken to be megabytes unless explicitly suffixed with Gb in
 164       order to specify the size in gigabytes.
 165
 166   --with-<feature>     Build with specified feature.
 167   --without-<feature>  Build wihout the specfied feature.
 168
 169   --fancy              Build with several optional features:
 170
 171                            $FANCY_FEATURES
 172
 173                        Plus threading on platforms which support it.
 174
 175   --arch=<string>      Specify the architecture to build for.
 176
 177       Mainly for doing x86 builds on x86-64.
 178
 179   --xc-host=<string>   Specify the Common Lisp compilation host.
 180
 181       The string provided should be a command to invoke the
 182       cross-compilation Lisp system in such a way, that it reads
 183       commands from standard input, and terminates when it reaches end
 184       of file on standard input.
 185
 186       Examples:
 187
 188        "sbcl --disable-debugger --no-sysinit --no-userinit"
 189                   Use an existing SBCL binary as a cross-compilation
 190                   host even though you have stuff in your
 191                   initialization files which makes it behave in such a
 192                   non-standard way that it keeps the build from
 193                   working. Also disable the debugger instead of
 194                   waiting endlessly for a programmer to help it out
 195                   with input on *DEBUG-IO*. (This is the default.)
 196
 197        "sbcl"
 198                   Use an existing SBCL binary as a cross-compilation
 199                   host, including your initialization files and
 200                   building with the debugger enabled. Not recommended
 201                   for casual users.
 202
 203        "lisp -noinit -batch"
 204                   Use an existing CMU CL binary as a cross-compilation
 205                   host when you have weird things in your .cmucl-init
 206                   file.
