I wanted to try out wxPython 3.0 on my machine running Linux Mint 17.2. Unfortunately, Ubuntu 14.04 LTS, that Mint is based on, only has wxPython 2.8 in its repository.

It turned out to be fairly easy to build my own packages for wxPython 3.0 though. Here’s a short summary on how to do it.

Download the debian sources for a newer version of Ubuntu:


The files I downloaded were:


But they might be updated when you read this, in that case, modify the commands below to match the current version.

Unpack the sources the same way that “apt source” usually does it:

xzcat wxpython3.0_3.0.2.0+dfsg.orig.tar.xz | tar xvf -
cd wxpython3.0-
xzcat ../wxpython3.0_3.0.2.0+dfsg-1build1.debian.tar.xz | tar xvf -

Install some tools to build Debian packages:

sudo apt-get install build-essential devscripts

Install some dependencies needed by wxPython itself:

sudo apt-get install python-all python-all-dev libgtk2.0-dev libwxgtk3.0-dev libwxgtk-media3.0-dev

Build the Debian packages. “-us -uc” tells debuild to skip signing the packages, “-b” tells debuild to only build the binary packages:

debuild -us -uc -b

You should now have a bunch of debian packages in the parent directory. On my computer I got the following:

cd ..
ls python-wx*.deb


All that’s left to do is to install them:

sudo dpkg -i python-wx*.deb

One more thing though. This will change the default version of wxPython on your system to 3.0. So any python application that does just does “import wx” will use version 3.0 instead of 2.8:

>>> import wx

This might break some other which did not expect that. I have not noticed any breakage so far, but if you want to be really safe, you can lower the priority of wxPython 3.0 so that 2.8 will be the default instead:

update-alternatives --install /usr/lib/wx/python/wx.pth wx.pth /usr/lib/wx/python/wx3.0.pth 0

>>> import wx

You can then explicitly select wxPython 3.0 in your application using the wxversion module:

>>> import wxversion
>>> wxversion.select('3')
>>> import wx

Now I just have to remember why I wanted wxPython 3.0 on my machine. It’ll come back to me soon I hope.
