 In order to build CMU CL, you will need:

-a. A working CMU CL binary.  There is no way around this requirement!

+1. A working CMU CL binary.  There is no way around this requirement!

    This binary can either be for the platform you want to target, in

    that case you can either recompile or cross-compile, or for another

    supported platform, in that case you must cross-compile, obviously.

-a. A supported C compiler for the C runtime code.

    Most of the time, this means GNU gcc, though for some ports it

    means the vendor-supplied C compiler.  The compiler must be

    Note for FreeBSD 10 and above: The build requires gcc (Clang will

    not work) and the lib32 compatiblity package.

-a. GNU make

+1. GNU make

    This has to be available either as gmake or make in your PATH, or

    the MAKE environment variable has to be set to point to the correct

    binary.

-a. The CMU CL source code

    Here you can either use one of the release source tarballs, or

    check out the source code directly from the public CMUCL git

 1. Create a base directory and change to it

+```

     mkdir cmucl ; cd cmucl

-2.) Fetch the sources and put them into the base directory

+2. Fetch the sources and put them into the base directory

     or, if you want to use the git sources directly:

+```

     git clone https://gitlab.common-lisp.net/cmucl/cmucl.git

+```

     Whatever you do, the sources must be in a directory named src

     inside the base directory.  Since the build tools keep all

    Use this to build from a version of CMUCL that is very close to the

    sources you are trying to build now:

+```

    bin/build.sh -C "" -o "<name-of-old-lisp> <options-to-lisp>"

+```

    This will build CMUCL 3 times, each time with the result of the

    previous build.  The last time, the additional libraries like CLX,

    For these, you can use this:

+```

    bin/build.sh -C "" -o "<old-lisp>" -B boot1.lisp -B boot2.lisp

+```

    The bootstrap files listed with the -B option (as many as needed)

    are loaded in order, so be sure to get them right.

 read the bootfiles for additional instructions, if any.

 * bin/create-target.sh target-directory [lisp-variant [motif-variant]]

-This script creates a new target directory, which is a shadow of the

-source directory, that will contain all the files that are created by

-the build process.  Thus, each target's files are completely separate

-from the src directory, which could, in fact, be read-only.  Hence you

-can simultaneously build CMUCL for different targets from the same

-source directory.

-remaining arguments are optional.  If they are not given, the script

-tries to determine the lisp variant and motif variant from the system

-the script is running on.

-

-The lisp-variant (i.e. the suffix of the src/lisp/Config.* to use as

-the target's Config file), and optionally the motif-variant (again the

-suffix of the src/motif/server/Config.* file to use as the Config file

-for the target's CMUCL/Motif server code).  If the lisp-variant is

-given but the motif-variant is not, the motif-variant is determined

-from the lisp-variant.

-

-The script will generate the target directory tree, link the relevant

-Config files, and generate place-holder files for various files, in

-order to ensure proper operation of the other build-scripts.  It also

-creates a sample setenv.lisp file in the target directory, which is

-used by the build and load processes to set up the correct list of

-*features* for your target lisp core.

-

-IMPORTANT: You will normally NOT have to modify the sample setenv.lisp

-file, if you are building from a binary that has the desired features.

-In fact, the sample has all code commented out, If you want to add or

-remove features, you need to include code that puts at least a minimal

-set of features onto the list (use PUSHNEW and/or REMOVE).  You can

-use the current set of *features* of your lisp as a first guide.  The

-sample setenv.lisp includes a set of features that should work for the

-intended configuration.  Note also that some adding or removing some

-features may require a cross-compile instead of a normal compile.

 Step-by-Step Example of recompiling CMUCL for OpenBSD

 -----------------------------------------------------

 Set up everything as described in the setup section above. Then

 execute:

-

+```

 # Create a new target directory structure/config for OpenBSD:

 bin/create-target.sh openbsd OpenBSD_gencgc OpenBSD

 # core will announce.  Please always put the build-date and some

 # other information in there, to make it possible to differentiate

 # those builds from official builds, which only contain the release.

+```

 Now you should have a new lisp.core, which you can start with

-

+```

 ./openbsd/lisp/lisp -core ./openbsd/lisp/lisp.core -noinit -nositeinit

+```

 Compiling sources that contain disruptive changes

 -------------------------------------------------

 -c, -r, and -l options for cross-build-world.sh.  The -c option cleans

 out the targe and cross directories; -r does step 4; and -l does step

 5.
