 139 \`make.sh' drives the SBCL build.
 140
 141 Usage: $0 [OPTION]...
 142
 143   Important: make.sh does not currently control the entirety of the
 144   build: configuration file customize-target-features.lisp and certain
 145   environment variables play a role as well. see file INSTALL for
 146   details.
 147
 148 Options:
 149   -h, --help           Display this help and exit.
 150
 151   --prefix=<path>      Specify the install location.
 152
 153       Script install.sh installs SBCL under the specified prefix
 154       path: runtime as prefix/bin/sbcl, additional files under
 155       prefix/lib/sbcl, and documentation under prefix/share.
 156
 157       This option also affects the binaries: built-in default for
 158       SBCL_HOME is: prefix/lib/sbcl/
 159
 160       Default prefix is: /usr/local
 161
 162   --dynamic-space-size=<size> Default dynamic-space size for target.
 163
 164       This specifies the default dynamic-space size for the SBCL
 165       being built. If you need to control the dynamic-space size
 166       of the host SBCL, use the --xc-host option.
 167
 168       If not provided, the default is platform-specific. <size> is
 169       taken to be megabytes unless explicitly suffixed with Gb in
 170       order to specify the size in gigabytes.
 171
 172   --with-<feature>     Build with specified feature.
 173   --without-<feature>  Build wihout the specfied feature.
 174
 175   --fancy              Build with several optional features:
 176
 177                            $FANCY_FEATURES
 178
 179                        Plus threading on platforms which support it.
 180
 181   --arch=<string>      Specify the architecture to build for.
 182
 183       Mainly for doing x86 builds on x86-64.
 184
 185   --xc-host=<string>   Specify the Common Lisp compilation host.
 186
 187       The string provided should be a command to invoke the
 188       cross-compilation Lisp system in such a way, that it reads
 189       commands from standard input, and terminates when it reaches end
 190       of file on standard input.
 191
 192       Examples:
 193
 194        "sbcl --disable-debugger --no-sysinit --no-userinit"
 195                   Use an existing SBCL binary as a cross-compilation
 196                   host even though you have stuff in your
 197                   initialization files which makes it behave in such a
 198                   non-standard way that it keeps the build from
 199                   working. Also disable the debugger instead of
 200                   waiting endlessly for a programmer to help it out
 201                   with input on *DEBUG-IO*. (This is the default.)
 202
 203        "sbcl"
 204                   Use an existing SBCL binary as a cross-compilation
 205                   host, including your initialization files and
 206                   building with the debugger enabled. Not recommended
 207                   for casual users.
 208
 209        "lisp -noinit -batch"
 210                   Use an existing CMU CL binary as a cross-compilation
 211                   host when you have weird things in your .cmucl-init
 212                   file.
