wxMaxima is written is C++ and uses wxWidgets. The sources are in git repository hosted at github.


Use github issues page to submit bug reports or feature requests.


Current wxMaxima source code is available in git repositories at sourceforge and github. Clone the repository with

git clone
One has to note, though, that on some linux systems the F1, Tab and Delete keys only work with wxWidgets if ibus-gtk3 is installed; Build instructions can be found on the bottom of the github page containing the source of wxMaxima.

Nightly Builds

Install a Nightly Build of wxMaxima


The result of the latest nightly build attempt on windows can be queried at Wolfgang Dautermann's site. His site also offers to download the current build of wxMaxima as a zip archive whose content can replace the wxMaxima folder of any existing maxima installation. In the case that the wxmaxima directory of the local install comes with the wrong dlls the needed dlls for the nightly build can be downloaded here:

If building the current code did result in an error the files that couldn't be built are left out of the archive; The .exe file that resulted from this build can be downloaded separately, too: Typically the rest of the files in a wxMaxima installation doesn't change frequently so an update of wxmaxima.exe might be all that is needed in order to get the newest version.


A nightly build of wxMaxima can be downloaded from Launchpad. This page also contains information on how to make debian-based system automatically keep updating to the latest build. For a one-time install downloading the .deb file and double-clicking on it should suffice on most systems. Alternatively the file can be installed from the console, on debian-based systems by typing sudo dpkg -i filename.deb; The build logs can be accessed using this page.


The result from trying to compile the latest version from the repository can be viewed at A new compile is triggered at every commit to the wxMaxima repository.

Updating maxima to the last version, as well

On Linux updating maxima to the current git head should be straightforward. David Scherfgen posted the following procedure that allows to update the current maxima installation to the git head on windows, too, without having to install any traditional build tools.

  1. Install the latest "stable" Maxima build for Windows from We will use the wxMaxima version that comes with this build and just replace Maxima itself.
  2. If you don't have one, install a Git client for Windows from or
  3. Clone the Maxima Git repository into some directory. In this guide, I will assume that this is C:\Maxima-Git. The repository's URL is git://
  4. If you don't have it already, install Steel Bank Common Lisp (SBCL) for Windows from Since I'm on a 64-bit Windows, I chose the 64-bit version, and it worked fine.
  5. Now we will build Maxima using SBCL only. For that, precisely follow the instructions found in the INSTALL.lisp file in C:\Maxima-Git:
    1. Open a command prompt and CD to C:\Maxima-Git.
    2. Start SBCL by entering: sbcl
    3. Now we configure Maxima by entering (load "configure.lisp"), then (configure), and finally (quit)
    4. Navigate to the C:\Maxima-Git\src directory by typing: cd src
    5. Start SBCL again: sbcl
    6. Now we compile Maxima by entering (load "maxima-build.lisp"), then (maxima-compile), and finally (quit)
    7. Start SBCL again: sbcl
    8. Now we load the compiled Maxima program by entering (load "maxima-build.lisp") again, then (maxima-load)
    9. Finally, we dump an image by entering (maxima-dump)
  6. After these steps, you should have a compiled version of the latest Maxima. Verify that everything worked by running the maxima.bat file that you should find in C:\Maxima-Git\src. The Maxima command prompt should show up.
  7. Now we will make wxMaxima use our self-compiled Maxima version:
    1. Open an Explorer window and go to the bin subdirectory of your latest "stable" Maxima version. For me, this is C:\Program Files (x86)\Maxima-sbcl-\bin.
    2. Rename the maxima.bat file to maxima.bat.bak.
    3. Rename the sbcl.exe file to sbcl.exe.bak. You need to do this because the supplied version of SBCL seems to be outdated, and that would result in troubles. By renaming the file, the SBCL version you earlier installed on your machine will be used instead.
    4. Copy C:\Maxima-Git\src\maxima.bat to the current directory.
  8. Verify that everything worked by starting wxMaxima and entering build_info(); - pay attention to the timestamp field, which should reflect the date and time when you compiled Maxima earlier.
  9. That's it! From time to time, you should pull new commits from the repository and rebuild Maxima by following step 5 again. Copying the files again (step 7) should not be necessary.
  10. If you want to undo the changes, delete the maxima.bat file and rename maxima.bat.bak back to maxima.bat and sbcl.exe.bak back to sbcl.exe.
