Build wxPython On Raspberry PiContentsBuild wxPython On Raspberry PiOptional:Build and Install:Notes:?Instructions by?James KeyThese are the build and install instructions.This does not seem to work with GTK3 at the moment. So we will stick with GTK2.READ THEM ALL FIRST!Especially the note at the end.The first part of this is optional. I have tested this on both Python?3.4 (the default Pi install for Jessie) Python 3.5(Stretch) and on Python 3.6.4. To use Python 3.6 you?need to install it first, which mean building it.If you wish, update the version numbers to the latest release. I know that this version?works, and it's the most recent as of the writing of these directions.These instructions are based on the Github gist:: used Python 3.5 (installed)First we need to setup the build dependencies. $ sudo apt-get update $ sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-devThen download and build Python. $ wget $ tar xf Python-3.6.4.tar.xz $ cd Python-3.6.4 $ ./configure –-enable-optimizations $ make $ sudo make altinstallBuild and Install:Okay so you want or need wxPython 4.0.x on your Raspberry Pi or you like?to watch lots of messages scroll by on long builds. Either way this is?how to do it.First things first MAKE A VIRTUAL ENVIORNMENT for the build and install.?Okay this isn't strictly needed but if you don't know about venv or?virtual environments, they do keep the environment cleaner for each?project. The only issue is that you need to run the pip install for each?virtual environment you want to use it in. It's your choice.These instructions will use Python 3.4 but they are identical for 3.6,?just substitute the version number you want. For example: $ python3.4 ...would be $ python3.6 ...Not too scary, right?These instructions are based on the Github Phoenix README: now to make the virtual environment. I made mine right off the?/home/pi directory but you can put it anywhere. Some like to put all?there virtual environments (virtenv) in specific locations.Lets make one (wx is the name of the virtenv we are creating, change it?to suit): $ cd ~ $ Python 3.5 -m venv wx $ source ~/wx/bin/activateThe last line activates the environment. Your prompt should change to?show that you are in an active virtenv. To deactivate type deactivate.?If you log out, close the terminal, or restart the Pi, or open a new?terminal, you need to run the activate command again. If not you won't?be in the virtual environment.If your lazy like most programmers. Check out? some fussing the virtenv will load automagically when you enter a directory.First thing you need is wxPython. Go to: first link will give you a choice of releases, as before I tested?4.0.0b2 and it works, but you might get here later and a newer release is?available. PLEASE use the tarball from these links, I too wanted the?latest, greatest version. Don't. If you download it from github you need?to do a massive amount of work.?Let the marvelous people who developed this package do that, then thank them.Down at the bottom of the choices you'll see?“wxPython-4.0.1.tar.gz …?Source”.See what version you actually download – in this case 4.0.4 and change commands accordingly.wxPython-4.0.4.tar.gzDownload wxPython-4.0. 4.tar.gzUse your browser if you can. The the link currently is the very human unfriendly: that's not exactly a professional comment but sometime you just have to call it what it is. $ cd ~ $ mv ~/Downloads/wxPython-4.0. 4.tar.gz . $ tar xf wxPython-4.0. 4.tar.gzOkay here we go. Let's make sure we have the dependencies. $ sudo apt-get update $ sudo apt-get install dpkg-dev build-essential libjpeg-dev libtiff-dev libsdl1.2-dev libgstreamer-plugins-base0.10-dev libnotify-dev freeglut3 freeglut3-dev libwebkitgtk-devIf you are using Python 3.6 you are all set to continue but if you are using the?pre-installed Python 3: (check which Python version you have) $ sudo apt-get install python3. 5-devNext step, make sure you are in the environment you want to install?wxPython into. $ cd wxPython-4.0. 4 $ pip3 install -r requirements.txtOkay the next part is the big one. This will take a while, anywhere from?a few hours, to 18+ hours on a Pi zero. (~4hrs RPi3B+) $ python3 build.py build bdist_wheel --jobs=1 --gtk2Now to install it in Python as a package: (look in ~/wxPython-4.0.1/dist for cpX) $ cd ~/wxPython-4.0.1/dist $ pip3 install wxPython-4.0.1-cp35-cp35m-linux_armv7l.whlNow let’s test it: $ cd ~/wxPython-4.0.1/demo $ python3 demo.pyNotes:The build.py script has many options, but I will warn you unless you?know what your doing, don't play with them. I had built the package for?ver 3.4 then decided to try 3.6. So I ran the cleanall option to clean?out the last builds binaries. It did and it cleaned all the SIP and?Doxygen bits out too. That defeated the whole point of me getting the?pypi tarball. To clean up, delete the directory and extract it again.Beware you may need an SD card larger than 16MBs**Other things to note**?There were a few times that my pi seemed to?freeze. Leave it alone for awhile. Give it 15-20 minutes. If it doesn't?recover unplug it, enable the virtenv and restart by using your last?command. Usually the 'pip install'. Above all don't panic. ................
