143 -h, --help Display this help and exit.
145 --prefix=<path> Specify the install location.
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.
151 This option also affects the binaries: built-in default for
152 SBCL_HOME is: prefix/lib/sbcl/
154 Default prefix is: /usr/local
156 --dynamic-space-size=<size> Default dynamic-space size for target.
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.
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.
166 --with-<feature> Build with specified feature.
167 --without-<feature> Build wihout the specfied feature.
169 --fancy Build with several optional features:
173 Plus threading on platforms which support it.
175 --arch=<string> Specify the architecture to build for.
177 Mainly for doing x86 builds on x86-64.
179 --xc-host=<string> Specify the Common Lisp compilation host.
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.
