Unable to install matplotlib on Mac OS X

I'm trying to install matplotlib for graphing applications in Python on Mac OS X. When I run "python setup.py install", it gives me this load of errors: http://pastebin.com/u7fL37ic.

A quick snippet:

src/ft2font.cpp:2170: error: ‘FT_LOAD_TARGET_MONO’ was not declared in this scope
src/ft2font.cpp:2171: error: ‘FT_LOAD_TARGET_LCD’ was not declared in this scope

src/ft2font.cpp:2175: error: ‘_ft2Library’ was not declared in this scope
src/ft2font.cpp:2175: error: ‘FT_Init_FreeType’ was not declared in this scope
src/ft2font.cpp: In destructor ‘virtual ft2font_module::~ft2font_module()’:
src/ft2font.cpp:2186: error: ‘_ft2Library’ was not declared in this scope
src/ft2font.cpp:2186: error: ‘FT_Done_FreeType’ was not declared in this scope
lipo: can't figure out the architecture type of: /var/folders/Nj/Njnlp9qSF64sMESWcaDnk++++TI/-Tmp-//cchyYmM5.out
error: command 'gcc-4.0' failed with exit status 1

I installed freetype using MacPorts, and I thought that would fix the issue, but no luck. Gives me same error as before. It looks like it can't find the right freetype files:

BUILDING MATPLOTLIB
        matplotlib: 1.0.0
            python: 2.6.5 (r265:79359, Mar 24 2010, 01:32:55)  [GCC

Where should I put the freetype files so that they can be found? Right now they're in /opt/local/lib

Any ideas?

I was able to get this to work without modifying my PATH etc. It seems my problem was the freetype library (installed with brew) not being found when using a non-brew python

brew install python
brew install freetype
# maybe more dependencies

Then create a virtualenv using the brew python (without explicitly specifying the path to the brew python I found that the brew virtualenv would still use the default OSX /usr/bin/python):

/usr/local/bin/virtualenv -p /usr/local/bin/python env
source env/bin/activate
pip install matplotlib

I would highly recommend the StrongInference Scipy Superpack. It works with the built-in Apple supplied Python on 10.6 Snow Leopard, and this is now working with 10.9. It's friendly to both 32-bit and 64-bit installs. It does not require installing a separate Python distribution or package managers like Macports or Fink.

Use it by first downloading the shell script from this page. Then:

sh superpack_10.6_2011.03.07.sh

Or, replace superpack_10.6_2011.03.07.sh with the name of the latest shell script as they update it from time to time.

To use it, make sure you type in ipython and not python!

Try symlinking freetype2 to freetype:

ln -s /usr/local/opt/freetype/include/freetype2/ /usr/local/include/freetype

I was having the same problem when trying to install matplotlib. After trying some of the above solution, I just ran

brew install freetype

then, the installation went well until it ran into a png.h not found. I ran

brew install libpng

The installation finished and matplotlib was installed.

(on os X 10.8.4)

Running into this every time I build matplotlib. My solution:

export CFLAGS=-I/usr/X11/include/freetype2
python setup.py install

Old, but still popped up in my search when I had the same problem on Snow Leopard.

You said you were using homebrew, so you need to

brew link freetype

after installing it (with "brew install freetype").

This got through that error. I had do the same thing with libpng, which resulted in a successful install.

I like using the brew, and none of the top three explanations worked or were enticing to me. However, I did look some more, and found this brew friendly explanation and solution:

http://jholewinski.org/blog/installing-matplotlib-on-os-x-10-7-with-homebrew/

Summary: libpng on Snow Leopard isn't on friendly terms with matplotlib. You can manually install the un-released matplotlib to work around it:

brew install python
brew install gfortran
brew install pkg-config
easy_install pip
pip install numpy
git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
python setup.py build
python setup.py install

The root of the problem is that freetype and libpng are installed in non-canonical locations by XCode, in /usr/X11 instead of /usr or /usr/local.

All of the answers already given address the problem by re-building freetype and libpng, either manually or using a package manager like homebrew.

You can, however, get matplotlib to compile by simply symlinking the existing freetype/libpng headers and libraries into the /usr/local tree with:

sudo mkdir -p /usr/local/include
sudo ln -s /usr/X11/include/freetype2/freetype /usr/local/include/freetype
sudo ln -s /usr/X11/include/ft2build.h /usr/local/include/ft2build.h
sudo ln -s /usr/X11/include/png.h /usr/local/include/png.h
sudo ln -s /usr/X11/include/pngconf.h /usr/local/include/pngconf.h
sudo ln -s /usr/X11/include/pnglibconf.h /usr/local/include/pnglibconf.h
sudo mkdir -p /usr/local/lib
sudo ln -s /usr/X11/lib/libfreetype.dylib /usr/local/lib/libfreetype.dylib
sudo ln -s /usr/X11/lib/libpng.dylib /usr/local/lib/libpng.dylib

I prefer to build python packages with pip, so I would then use:

sudo pip install matplotlib

If you don't already have pip, you can install it with easy_install (which comes with OS X):

sudo easy_install pip

I've only tested this on 10.7 (Lion) but I suspect it will also work with 10.6.

It is a little bit of a hack, but I've found it to be the easiest way to get matplotlib installed against the stock python framework that ships with OS X. The stock python framework in 10.7 is actually pretty good, and includes, for instance, a numpy-1.5.1 package that is linked against Apple's optimized BLAS library (Accelerate):

dyldinfo -dylibs /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/numpy/linalg/lapack_lite.so 
for arch x86_64:
attributes     dependent dylibs
            /System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate
            /usr/lib/libSystem.B.dylib

I got a similar error - you're missing the development files for libfreetype - on my linux machine - this is libfreetype6-dev

After I installed this pip did it's job.

I followed this page's instructions. I got stuck at 

pip install -e git+https://github.com/matplotlib/matplotlib#egg=matplotlib-dev

Then I did:

git clone https://github.com/matplotlib/matplotlib.git
cd matplotlib
python setup.py build
python setup.py install

Checked my installation by typing in terminal:

python
import matplotlib
print matplotlib.__version__
print matplotlib.__file__

I got version 0.10.0 dev (as of this writing) and path /usr/local/Cellar/...

I was given a new work computer recently (MacBook Pro OS 10.6.5), and wanted to install numpy + scipy + matplotlib in a Python virtual environment. I'm not an expert, but the virtual environment seems to allow you to install packages such that they are isolated from the system-wide packages, essentially by redefining the system path in a clever way. So, for one project I am working on that requires certain versions of these packages, I can install them once and do all of my work for that project there, independently of other changes I make outside the environment.

After a lot of trial and error, I was able to build a virtual environment with Numpy 1.5.1, Scipy 0.8.0, and Matplotlib 1.0.0 all running flawlessly. Here's how:

First, install the following four packages:

(I'm a new user so I can't post links to these, sorry!).

If you install from source, use a standard install:

  • $ ./configure
  • $ make
  • $ sudo make install

Next, download the source files for numpy, scipy, and matplotlib.

Now it's time to create a virtual environment in folder TESTENV:

$ virtualenv /path/to/dir/TESTENV

Activate the virtual environment:

$ source . /path/to/dir/TESTENV/bin/activate

Now, python packages will be installed within TESTENV as if it were the root installation directory. What worked for me was to execute:

$ python setupegg.py install

in the numpy, scipy, and matplotlib source folders (in that order).

Hope that helps!

Here's how I did it:

$ sudo make -f make.osx fetch deps mpl_build mpl_install

This will install it in /lib/python2.6/site-packages, just move its contents to /Library/Python/2.6/site-packages/ for consistency.

you may also consider using the Enthought distribution (which comes even free for non-commercial usage) It comes fully installed without any difficulty http://www.enthought.com/products/getepd.php (I have no relationship with Enthought whatsoever - I'm just a satisfied user)
