Linux

Download: p9m4-source.zip

You'll need Python 3.8 (or later) and wxPython.
Unpack the source code archive and run prover9-mace4.py.

Below is the archive of the last version made available by William McCune.

Prover9-Mace4 v05

The Prover9-Mace4 GUI uses version LADR-Dec-2007 of Prover9 and Mace4. If you need a more recent verion of Prover9 or Mace4, you'll have to use a command-line version.

This is a Graphical User Interface for Prover9 and Mace4.
It was constructed with Python and the WX widget library.
The target platforms are Windows (2000 or later), Mac OS X (10.3.9 or later), and Linux.
To get started:
- Install the GUI (see the following sections).
- Start the GUI and see "File->Sample Inputs" and "Help".
- See the Prover9/Mace4 Manual and Examples.
The GUI contains Prover9 and Mace4, so there is no need to also install the LADR system.

Windows

Download: Prover9-Mace4-v05-setup.exe (about 5.2 MB)

This will lead you through a standard Windows installation. (You have to be an administrator.)

Known Windows Problems

When both Prover9 and Mace4 are running, the GUI response is slow.
Automatic syntax highlighting is annoying, so it is disabled on startup.
If you try to start the GUI and you see an error message that the dll MSVCP71.DLL is missing, you can download it here: MSVCP71.DLL, and then place it in the directory "C:\Program Files\Prover9-Mace4".

Macintosh

Download: Prover9-Mace4-v05B.zip (about 9.2 MB)

If you put this on your Desktop and open (unzip) it, the Prover9-Mace4 app should appear on your Desktop.

Known Mac Problems

NOTE (March 14, 2008): There is a bug in the December 2007 version (Prover9-Mace4-v05.zip), which caused changes in the parameters (max_seconds, etc.) to not be sent to Prover9 or Mace4. Version v05B contains a fix. This problem does not occur in the Linux or Windows versions.
On an old iBook (G3 with 10.3.9), the text boxes that contain a lot of output (>32K?) don't show scrollbars. All of the text really is there, so it can be 'Save'd. This problem did not occur on the Intel Macs (10.4, 10.5) we used for testing.

Linux

Download: p9m4-v05.tar.gz (about 1.7 MB)

This is not a self-contained package like the Windows and Mac versions.
You'll need Python 2.5 (or later) and Python-wxgtk2.6 (or later).
In Ubuntu, you can install packages python2.5 and python-wxgtk2.6.
Unpack p9m4-v05.tar.gz and run p9m4-v05/prover9-mace4.py.

Known Linux Problems

If startup fails with an error "OverflowError: argument number 7: value -9223372036854775807 is less than 'int' minimum -2147483648", it is caused by a bug in wxPython 64-bit systems. To get around the bug, insert the following line in the file options.py at line 30.
```
sys.maxint = 2147483647  # avoids bug in wx.SpinCtrl on 64-bit systems
```
The included prover binaries (prover9, prooftrans, mace4, interpformat, isofilter, isofilter2) are compiled for i386. If you have different hardware, you can fetch LADR-Dec-2007.tar.gz, compile, and replace those 6 binaries in the directory p9m4-v04/bin.
