Question

I asked a question a couple of days ago regarding installing numpy on the same system. Thankfully, I managed to solve that one myself but unfortunately I am now stuck trying to install matplotlib.

I first of all tried the current distributed version but had no luck with that so I thought i would download the git repository and try that. I have got this far:

• changed the make.osx file so that it will work in Python 3:
  • import urllib -> import urllib.request
  • urllib.urlretrieve() -> urllib.request.urlretrieve()

Even after that I still had a problem with it not finding the freetype2 headers. I googled around and discovered that I could solve this by editing a line in setupext.py:

• 'darwin' : [], -> 'darwin' : ['/usr/local'],

However, I still get an error message when using the make.osx file. Here is how I am calling the file from Terminal:

• sudo make -f make.osx PREFIX=/usr/local PYVERSION=3.2 fetch deps mpl_build mpl_install

I realise that matplotlib isn’t officially supported on Python 3 yet but I thought that maybe someone somewhere as at least managed to get it to compile/install?

Any help would be much appreciated,

Adam.

I have included the error I get below:

Okay…I think have managed to get matplotlib to install now…

1. First of all you need to install numpy. I have instructions to do this on another post: install numpy

2. Now open Terminal and clone the git repository for matplotlib (assumes you have git installed):

   • git clone git://github.com/matplotlib/matplotlib.git (this might take a while)

3. Once the clone is complete open your user folder in Finder

4. In your user folder open the matplotlib directory

5. There is a file called `make.osx’ open this with TextEdit (or similar)

6. Change the following lines:

   • MACOSX_DEPLOYMENT_TARGET=10.6
   • OSX_SDK_VER=10.6

   To:

   • MACOSX_DEPLOYMENT_TARGET=10.7
   • OSX_SDK_VER=10.7

7. Change the following lines:

   • ${PYTHON} -c 'import urllib; urllib.urlretrieve("${ZLIBURL}", "${ZLIBFILE}")' &&\
${PYTHON} -c 'import urllib; urllib.urlretrieve("${PNGURL}", "${PNGFILE}")' &&\
${PYTHON} -c 'import urllib; urllib.urlretrieve("${FREETYPEURL}", "${FREETYPEFILE}")'

   To:

   • ${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${ZLIBURL}", "${ZLIBFILE}")' &&\
${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${PNGURL}", "${PNGFILE}")' &&\
${PYTHON} -c 'import urllib.request; urllib.request.urlretrieve("${FREETYPEURL}", "${FREETYPEFILE}")'

8. Save the changes

9. Open the file called setupext.py in idle

10. Find the line 'darwin' : [], and change it to 'darwin' : ['/usr/local'],

11. Save the file

12. Open Terminal again and type the following:

    • sudo make -f make.osx PREFIX=/usr/local PYVERSION=3.2 fetch deps mpl_build mpl_install

13. After some time matplotlib should be installed in the following directory:

    • /usr/local/lib/Python3.2/site-packages/

14. Open the above directory and also the following directory:

    • /Library/Python/3.2/site-packages/

15. Copy/move the following directories from /usr/local/lib/Python3.2/site-packages/ to /Library/Python/3.2/site-packages/:

    • dateutil
    • matplotlib
    • mpl_toolkits

16. matplotlib should be now installed

17. If you open idle and type import matplotlib it shouldn’t return an error

18. I tried out the matplotlib/examples/user_interfaces/embedding_in_qt4_wtoolbar.py file and it seems works fine

Hope someone else finds this useful!

Thanks again for the assistance,

Adam.
