How To Install Pycairo 1.10 On Mac Osx With Default Python

Has anyone installed pycairo 1.10 on the mac using the new waf build? Its failing on can't find python headers.

Solution 1:

I think waf is seriously broken for Mac OS X :(

Here's how it worked for me. After python waf configure failed to find Python.h, I looked through the config.log file located in build_directory and found out that the true cause of failure was incompatible architecture. The waf script tries to build a simple source file with CPython calls in it using i386 architecture. It fails to do so, because my python is built for the x86_64 architecture.

I guess, you could rebuild python as a universal binary, I haven't tried that. It is possible, however, to build pycairo using the x86_64 architecture. Here's how.

My setup:

$ python --version
Python 2.7.2

$ type python
python is /usr/local/bin/python

$ file /usr/local/bin/python
/usr/local/bin/python: Mach-O 64-bit executable x86_64

$ brew --version0.8

Importrant: my python version is built for the x86_64 architecture. Make sure it is also the case for you before performing the steps described below.

brew stands for homebrew. You must use it instead of fink or MacPorts in order for the following steps to work for you.

Now, to install cairo and pycairo I do the following:

1. brew install cairo (version 1.10.2 as of today)

2. Get pycairo source for python 2.x (if you get a snapshot, it is named py2cairo, whereas pycairo now requires python 3.x). I used the source from master branch (commit f3435910d8f5365b45ebd4216f4043383c9e3e19)

3. Open wscript in your editor of choice, locate the line env = ctx.env in the function configure and add the following line below it

   env.append_unique('CFLAGS', ['-arch', 'x86_64'])

4. Save the file

5. Run these commands in your terminal:

   export CC=/usr/bin/gcc

   export PKG_CONFIG_PATH=/usr/local/Cellar/cairo/1.10.2/lib/pkgconfig/

   Important: the latter path will only work for you if you installed cairo via homebrew

6. Then run the waf commands described in the pycairo's INSTALL file:

   python waf configure

   python waf build

   python waf install

This should do it. If it doesn't work for you, I think it's better to raise the topic on the pycairo mailing list (if it has one).

Solution 2:

android's step almost works. one needs to use (from llimllib):

export ARCHFLAGS='-arch x86_64'

in step 5, and then python waf install can succeed.
