ACL2 Version 6.4 Installation Guide

NOTE: From time to time we may provide so-called incremental releases of ACL2. Please follow the recent changes to this page link on the ACL2 home page for more information.

Easy Install for Unix-like Systems

Here, "Unix-like Systems" includes Unix, GNU-Linux, and MacOS X.

NOTE: A quicker and even easier install may be possible, by instead obtaining a pre-built binary distribution if one is available for your platform. Otherwise:

  1. Fetch acl2.tar.gz into a new directory, say acl2/v6-4/.
  2. Execute the following to create directory acl2-sources/:
    tar xfz acl2.tar.gz
  3. We strongly suggest that you fetch the ACL2 community books, for example as a tarball from the acl2-books project website, into your new acl2-sources/ directory; then execute the following in acl2-sources/ to create a books/ subdirectory:
    tar xfz books-6.4.tar.gz
  4. Obtain a Common Lisp implementation if you don't already have one.
  5. Build by connecting to your acl2-sources/ directory and typing the following, which may take a few minutes to complete. Note: You will need Gnu make. We have seen rare problems with Version 3.81 of that utility, so if you encounter errors, please consider our instructions for downloading and installing GNU make version 3.80.
    make LISP=<path_to_your_lisp_executable>
  6. This will create a script in your acl2-sources directory for running ACL2, named saved_acl2.
  7. OPTIONAL: Download gzipped tarfiles for workshops books and/or nonstd books from the Google Code website into the books/ directory (but first create books/ if you skipped that step). Further instructions are here.
  8. Certify books (but first create books/ if you skipped that step), for example with
    make regression
    or something fancier such as:
    (time nice make -j 8 ACL2=/u/smith/bin/acl2 regression) >& make-regression.log
    The resulting log file, make-regression.log, should contain no occurrences of the string ``CERTIFICATION FAILED''; a normal exit (status 0) should guarantee this. If you want additional explanation and further options, see the documentation for BOOKS-CERTIFICATION.
You now have an ACL2 executable called saved_acl2 (from step 5) and access to certified community books (from step 7). Enjoy!
