You should typically obtain the distributed books and a local copy of the documentation. Start here and we will take you through the whole process of obtaining and installing ACL2. First, create a directory in which to store ACL2 Version 6.3. We will call this directory dir. For example, dir might be /home/jones/acl2/v6-3. NOTE: If you intend to obtain an incremental release (e.g. 2.9.4 as opposed to 2.9), please see the ACL2 News for instructions. Otherwise, continue reading here.A collection of books (ACL2 input files typically including definitions and theorems) has been developed over the years for use with ACL2, called the "community books". It is very useful to obtain these books, which are distributed from the Google Code acl2-books project website; directions are included below. Pre-built Binary Distributions Visit the "Recent changes to this page" link on the ACL2 home page to see if there are other shortcuts available.WARNING: Some of these packages might be for old version of ACL2. We recommend that you use the latest version of ACL2 (Version 6.3). Linux/Mac/Windows Binaries in ACL2sThe ACL2 Sedan (ACL2s) is an Eclipse-based IDE for ACL2 that is distributed with pre-certified books and pre-built binaries. If you use an alternative development environment (such as Emacs), you can still fetch a tarball for your x86-based Linux/Mac/Windows system that contains a pre-built binary of (pure) ACL2, using the following instructions based on information kindly provided by Harsh Raju Chamarthi. Just extract the appropriate tarball (using tar xfz on Linux or Mac and unzip on Windows) under a path with no spaces. Then run the script you will find, run_acl2 on Linux or Mac and run_acl2.exe on Windows, to start an ACL2 session. (Note that The first time you execute that command, the certificate (.cert) files are automatically fixed, according to the full pathname of your books/ directory.) Also see the ACL2 documentation topic on the ACL2 Sedan. WindowsIn the past, a Windows Installer for ACL2 has included a Unix environment, pre-certified standard and workshop books, and a copy of Gnu Emacs. This capability has largely been superseded by the section on Building an Executable Image on Some Particular Systems and the Shortcut using the ACL2 Sedan, above. See also information about ACL2 on Windows. MacPorts for Mac OS XACL2 versions have sometimes been made available under MacPorts. If we learn that an up-to-date version is available, we will add instructions here. Debian GNU LinuxA Debian Gnu Linux package is available, which is likely to work on other Linux systems as well. Thanks to Camm Maguire for maintaining this package, and for pointing out that as Debian packages are simply ar and tar archives, they can be unpacked on any linux system, and who has said: "If someone is running Debian, all they want to do is 'apt-get install acl2', doing likewise for any optional add-on package they wish as well, e.g. emacs, infix, etc." Alternatively, Debian GNU Linux users may wish to download the Debian package for Linux. Or, see following annotated log, provided by Camm Maguire, to see another way to proceed. camm@localhost:~$ cd /tmp camm@localhost:/tmp$ mkdir a camm@localhost:/tmp$ cd a camm@localhost:/tmp/a$ wget ftp://ftp.debian.org/debian/pool/main/a/acl2/acl2*5.0*_{i386,all}*b ;;; or ftp, use browser, etc. I.e. download the .deb files.

ACL2 !> Obtaining the Sources and Community Books Obtain the sources and place them in directory dir as follows.(First, a note for Windows users only: we suggest that you obtain a Unix-like environment or, at least, download a utility such as djtarnt.exe to use with the -x option on gzipped tarfiles. WARNING: At least one user experienced CR/LF issues when using WinZIP, but we have received the suggestion that people untarring with that utility should probably turn off smart cr/lf conversion.) Save acl2.tar.gz on directory dir. (You can run md5sum and compare with acl2-tar-gz-md5sum if you wish to verify the transmission.) Execute the following four Unix commands. (Note: Gnu tar is preferred, as there have been some problems with long file names when using tar provided by SunOS. You may want to use the -i option, "tar xpvfi acl2.tar", if you have problems with other than Gnu tar. You can see if you have Gnu tar by running "tar -v".)cd dir tar xfz acl2.tar.gz rm acl2.tar.gz cd acl2-sources We strongly suggest that you now install the community books, using one of the following methods, while still connected to the new directory. Easy download. Fetch a gzipped tarfile of the community books from the Google Code website, and then extract as follows to create a books/ subdirectory: tar xfz books-6.3.tar.gz OR, obtain a read-only copy using svn as a new subdirectory, books/: svn checkout http://acl2-books.googlecode.com/svn/branches/6.3 books OR, for read-write access, become a member of the acl2-books project by contacting one of the project administrators (see the acl2-books project page). Then: svn checkout https://acl2-books.googlecode.com/svn/branches/6.3 books --username NOTE: The second and third methods provide all of the community books, but the first omits the workshops/ and nonstd/ subdirectories of these books/, which (respectively) are books contributed in support of papers presented at ACL2 workshops, and books for use with ACL2(r). You can fetch these easily as gzipped tarfiles, as follows, using the following links to the Google Code website. ACL2 Workshops books ACL2(r) books Then put the gzipped tarfile(s) in the acl2-sources/books/ directory, connect to that directory, and extract to create workshops/ and nonstd/ subdirectories, respectively: tar xfz workshops-6.3.tar.gz tar xfz nonstd-6.3.tar.gz Creating or Obtaining an Executable Image The next step is to create an executable image. The common approach is to build that image from the sources you have already obtained. However, you may be able to take a short cut by downloading an ACL2 image, in which case you can skip ahead to Summary of Distribution. Otherwise you should click on one of the links just below. Choose the last option if you are using a Common Lisp on which you cannot save an image (e.g., a trial version of Allegro Common Lisp). PLEASE NOTE: The available memory for ACL2 is determined by the underlying Common Lisp executable. If you need more memory, refer to your Common Lisp's instructions for building an executable. Building an Executable Image on a Unix-like System Building an Executable Image on Other than a Unix-like System Running Without Building an Executable Image Short Cut: Pre-Built ACL2 Images The site http://www.cs.utexas.edu/users/moore/acl2/v6-3/distrib/images/Readme.html contains links to ACL2 executables and packages. Each -md5sum file was created using md5sum. We may add additional links from time to time.Now proceed to Using ACL2. Building an Executable Image on a Unix-like System We assume you have obtained ACL2 and placed it in directory dir, as described above. If you downloaded a pre-built ACL2 image, you may skip this section. Connect to dir as above and executecd acl2-sources make LISP=xxx where xxx is the command to run your local Common Lisp. By default, if no LISP=xxx is specified, LISP=ccl is used. On our hosts, ccl is the name of Clozure Common Lisp (CCL), which can be obtained as explained in the Requirements document. This will create executable saved_acl2 in the acl2-sources directory. The time taken to carry out this process depends on the host processor but may be only a few minutes for a fast processor. The size of the resulting binary image is dependent on which Lisp was used, but it may be up to a couple hundred megabytes or so. This make works for the Common Lisps listed in Requirements document on systems we have tested. See the file acl2-sources/GNUmakefile for further details. If this make command does not work for you, please see the instructions below for other than Unix-like systems. You can now skip to Using ACL2. Building an Executable Image on Other than a Unix-like System Next we describe how to create a binary image containing ACL2 without using the `make' utility. If you are using a trial version of Allegro Common Lisp, then you may not be able to save an image. In that case, skip to Running Without Building an Executable Image. See also Building an Executable Image on Some Particular Systems, in case you want to skip directly to the instructions in one of its subtopics. Otherwise, proceed as follows. Your Common Lisp should be one of those listed in Requirements document. Filenames below should default to the dir/acl2-sources directory; please connect to that directory before continuing. Remove file nsaved_acl2 if it exists. Start up Common Lisp in the acl2-sources directory and submit the following sequence of commands. ; Compile (load "init.lisp") (in-package "ACL2") (compile-acl2) The commands above will compile the ACL2 sources and create compiled object files on your acl2-sources subdirectory. Now exit your Common Lisp and invoke a fresh copy of it (mainly to avoid saving an image with the garbage created by the compilation process). Again arrange to connect to the acl2-sources subdirectory. In the fresh Lisp type: ; Initialization, first pass (load "init.lisp") (in-package "ACL2") (load-acl2) (initialize-acl2) This will load the new object files in the Lisp image and bootstrap ACL2 by reading and processing the source files. But the attempt at initialization will end in an error saying that it is impossible to finish because a certain file was compiled during the processing, thus dirtying the image yet again. (If however the attempt ends with an error during compilation of file TMP1.lisp, see the first troubleshooting tip below.) So now exit your Common Lisp and invoke a fresh copy of it (again arranging to connect to your acl2-sources subdirectory). Then, in the fresh Lisp type: ; Initialization, second pass (load "init.lisp") (in-package "ACL2") (save-acl2 (quote (initialize-acl2)) "saved_acl2") You have now saved an image. Exit Lisp now. Subsequent steps will put the image in the right place. Remove osaved_acl2 if it exists. IF saved_acl2 and saved_acl2.dxl both exist THEN: move saved_acl2.dxl to osaved_acl2.dxl move saved_acl2 to osaved_acl2 and edit osaved_acl2, changing saved_acl2.dxl (at end of line) to osaved_acl2.dxl ELSE IF saved_acl2 exists THEN: move saved_acl2 to osaved_acl2 Move nsaved_acl2 to saved_acl2. For some Common Lisps, a file nsaved_acl2.suffix is created for some suffix. Move it to: saved_acl2.suffix Make sure saved_acl2 is executable. For Windows this involves two mini-steps: (a) Remove the "$*" from the saved_acl2 script (because Windows does not understand $*). Consequently, any arguments you pass to ACL2 via the command line will be ignored.(b) Rename saved_acl2 to saved_acl2.bat, for example by executing the following command. rename saved_acl2 saved_acl2.bat Building an Executable Image on Some Particular Systems Subtopics of this section are as follows. Special Case: Building an Executable Image on a Windows System using GCL Instructions from David Rager for building ACL2 on Windows Older instructions from Jared Davis for building ACL2 on Windows using mingw Special Case: Building an Executable Image on a Windows System using GCL You may want to skip this section and instead read Instructions from David Rager for building ACL2 on Windows. Or, you may be able to download a pre-built ACL2 image for Windows instead of reading this section.Otherwise here are steps to follow. FIRST get GCL running on your Windows system using ONE of the following two options. Note that GCL can be unhappy with spaces in filenames, so you should probably save the GCL distribution to a directory whose path is free of spaces. OR, obtain GCL for Windows systems from ftp://ftp.gnu.org/gnu/gcl/ or as explained above. You may wish to pick a .zip file from the cvs/ subdirectory (containing pre-releases) that has "mingw32" in the name. OR ELSE, perhaps you can build GCL on your Windows system from the sources. The mingw tools and the cygnus bash shell have been used to build distributed GCL executables. SECOND, create an appropriate GCL batch file. When we tried running the script gclm/bin/gclm.bat that came with gcl-cvs-20021014-mingw32 from the above ftp site, a separate window popped up, and with an error. Many ACL2 users prefer running in an emacs shell buffer. (We obtained emacs for Windows from ftp://ftp.gnu.org/gnu/windows/emacs/21.2/emacs-21.2-fullbin-i386.tar.gz.) The following modification of gclm.bat seemed to solve the problem (your pathnames may vary). @ % do not delete this line % @ECHO off set cwd=%cd% path C:\gcl\gclm\mingw\bin;%PATH% C:\gcl\gclm\lib\gcl-2.6.2\unixport\saved_gcl.exe -dir C:/gcl/gclm/lib/gcl-2.6.2/unixport/ -libdir C:/gcl/gclm/lib/gcl-2.6.2/ -eval "(setq si::*allow-gzipped-file* t)" %1 %2 %3 %4 %5 %6 %7 %8 %9 THIRD, follow the instructions for other than Unix-like systems above, though the resulting file may be called saved_acl2.exe rather than saved_acl2. FINALLY, create a file acl2.bat as explained in http://www.cs.utexas.edu/users/moore/acl2/v6-3/distrib/images/Readme.html.We hope that the above simply works. If you experience problems, the following hints may help. TROUBLESHOOTING: We tried building ACL2 on Windows XP on top of GCL, our attempt broke at the end of the "Initialization, first pass" step, while compiling TMP1.lisp. That was easily remedied by starting up a fresh GCL session and invoking (compile-file "TMP1.lisp") before proceeding to the next step. Yishai Feldman has provided some nice instructions at http://www.faculty.idc.ac.il/yishai/reasoning/win-install.htm, some of which we have tried to incorporate here. A useful point made there is that when you want to quit ACL2, use :good-bye (or (good-bye) which works even in raw Lisp). Or you can use (user::bye) in raw Lisp. The point is: Avoid control-c control-d, even thought that often works fine in emacs under Unix-like systems. If the above batch file does not work for some reason, an alternate approach may be to set environment variables. You may be able to add to the PATH variable gcl-dir\gcc\bin, where gcl-dir is the directory where GCL is installed. To get to the place to set environment variables, you might be able to go to the control panel, under system, under advanced. Alternately, you might be able to get there by opening My Computer and right-clicking to get to Properties, then selecting the Advanced tab. At one time, when GCL/Windows was release as Maxima, Pete Manolios suggested adding the system variable LD_LIBRARY_PATH with the value "maxima-dir\gcc\i386-mingw32msvc\include"; this may or may not be necessary for your GCL installation (and the path would of course likely be different). Running Without Building an Executable Image The most convenient way to use ACL2 is first to install an executable image as described above for Unix-like systems and other platforms. However, in some cases this is not possible, for example if you are using a trial version of Allegro Common Lisp. In that case you should follow the steps below each time you want to start up ACL2.We assume you have obtained ACL2 and placed it in directory dir, as described above for Unix-like systems or other platforms. (If you downloaded a pre-built ACL2 image, then you may skip this section.) Connect to subdirectory acl2-sources of dir, start up your Common Lisp, and compile by executing the following forms. This sequence of steps need only be performed once. (load "init.lisp") (in-package "ACL2") (compile-acl2) Now each time you want to use ACL2, you need only execute the following forms after starting up Common Lisp in subdirectory acl2-sources of dir. (load "init.lisp") (in-package "ACL2") (load-acl2) (initialize-acl2) Note. The resulting process includes the ACL2 documentation, and hence will probably be considerably larger (perhaps twice the size) than the result of running an executable image created as described above.Now proceed to read more about Using ACL2. Summary of Distribution The ACL2 distribution, acl2.tar.gz, includes the ACL2 source files as well as the following files and directories (and a few others not mentioned here). Note that a books/ directory is not included; see instructions above to fetch the community books. LICENSE ; ACL2 license file GNUmakefile ; For GNU make TAGS ; Handy for looking at source files with emacs doc/ ; ACL2 documentation in various formats emacs/ ; Some helpful emacs utilities installation/ ; Installation instructions (start with installation.html) saved/ ; Empty directory for backing up copies during make Also available are the following. images/: Some gzip'd tar'd executables; see images/Readme.html split/: The result of splitting up acl2.tar.gzBased on the preceding ACL2 release, we estimate that the entire acl2.tar.gz is about 7MB, which extracts to about 30MB, and the gzipped tarfile books-6.3.tar.gz (obtained as described above) is about 12MB, which extracts to about 70MB. Additional space is required to build an image, perhaps 50 to 300 megabytes depending on the platform (including the host Lisp); and more will be required to certify books.
