We thank David Rager for providing the following instructions, which we include verbatim and expect apply to future versions. Note: We recommend using CCL for Windows builds, in part so that interrupts (Control-C) will work. If you are using Windows, please note that there have been stalls using CCL 1.5 on Windows, though not with CCL 1.4. We have been told by a CCL implementor that this bug has been fixed, and people running CCL 1.5 under Windows at a revision less than 13900 should update.
I was able to get ACL2 3.6.1 to install and build the regression suite on Windows 7 with the following steps. I did not have to install cygwin.
Install MinGW. At the time of this writing, the following direct link works
If that direct link doesn't work, click on "Automated MinGW Installer" on the more general MinWG project files page.
Install MSys. At the time of this writing, the following direct link
If that direct link doesn't work, click on "MSYS Base System" on the more general MinWG project files page.
Realize that using "\" to indicate paths in windows confuses some linux programs and that you might need to use "/" sometimes.
After expanding the ACL2 sources, cd to that directory and type
something similar to the following (modify it to set LISP to your LISP
The "make.exe" that will be used is intentionally the MSys version, not the MinGW version.
rename saved_acl2 saved_acl2.bat
You can now make the regression suite by typing
make regression ACL2=c:/acl2-3.6.1/acl2-sources/saved_acl2.bat
[Note added later: you may need to add `
ACL2_CENTAUR=skip, for example if you have
issues with Perl.]
1I have intentionally ommitted instructions on how to setup a LISP on windows. However, I include one link that should suffice: Obtaining CCL
