Installing Prover9, Mace4, and Friends

Unix-like Systems

Here is a quick example for Unix-like systems, including Linux and Macintosh OS X. Visit the Prover9 Web page and download the current version of LADR. The filename should be something like Prover9-LADR-2026-3I.tar.gz; make sure that file is in your current directory. Run the following commands.
% tar xzf Prover9-LADR-2026-3I.tar.gz
% cd Prover9-LADR-2026-3I
% make all

Prover9, Mace4, Prooftrans, and several other programs should now be in the directory Prover9-LADR-2026-3I/bin. You can either include that directory in your search path or copy those programs to some directory that is already in your search path.

Microsoft Windows

Install Windows Subsystem for Linux (WSL), then follow the Unix instructions above.
