Installing PIL on OS X Lion

Question

I am trying to install PIL on Mac OSX 10.7.4 but after several hours attempt couldn't succeed. All the time I have encountered the same problem provided detail in pastebin link below. Enlighten me!!

Setting

tbc:~ mystic$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python

Pastebin

I searched and tried from several sources:

• One
• Two
• Three
• Four (Stackoverflow)
• Five

Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34)

Edited as suggested by jdi but still running through the same problem as shown in above pastebin link

tbc:jpeg-8c mystic$ xcode-select -version
xcode-select version 2003.
tbc:jpeg-8c mystic$ which xcode-select
/usr/bin/xcode-select
tbc:jpeg-8c mystic$ xcode-select -print-path
/Applications/Xcode.app/Contents/Developer
tbc:jpeg-8c mystic$

Further, I gave try with homebrew as suggested by the "the paul"

tbc:cellar mystic$ brew link jpeg
Linking /usr/local/Cellar/jpeg/8d... 3 symlinks created
tbc:cellar mystic$ brew install pil
Error: pil-1.1.7 already installed

This formula installs PIL against whatever Python is first in your path.
This Python needs to have either setuptools or distribute installed or
the build will fail.

Here is the log of .pip

Its complaining about

/Developer/SDKs/MacOSX10.6.sdk/usr/include/stdarg.h:4:25: error: stdarg.h: No such file or directory

but stdarg.h file is there at the same location.

I am not understanding why its trying to locate in MacOSX10.6.sdk as my current version of Lion isMacOSX10.7.sdk

Getting crazy!!!

Answer 1

If you are on Lion, using the newest XCode, then a potential problem for you is that they moved the location of the developer SDKs. Packages that expected them to live in /Developer/ would no longer find them as needed.

Reference this article about specifics:
http://www.agile-workers.com/web/2012/03/qt-qmake-osx_sdk-xcode/

But in summary, what you might need to do is run:
sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer
to point at the new location.

A manual fix might be to just symlink the SDK from /Applications/Xcode.app/Contents/Developer/... => /Developer/..., but I would first try the xcode-select tool.

Update: Some more suggestions based on your new updates

First off, I can't tell from what you posted whether PIL failed to build because of the SDK or not. If it built successfully, and you are using the standard apple python, then chances are the homebrew python path is not in your own python path.

$ python
>>> import sys
>>> sys.path.append("/usr/local/lib/python2.7/site-packages")
>>> from PIL import Image

If that still errors, then I suppose the issue is still related to missing SDK location. You could symlink the new location of the SDK to the old one with:

mkdir -p -v /Developer/SDKs
ln -s /Applications/Xcode.app/Contents/Developer/MacOSX10.6.sdk  /Developer/SDKs/MacOSX10.6.sdk

Or, you can try explicitly setting the the sdk path when you build pil:

brew remove pil
export SDKROOT=/Applications/Xcode.app/Contents/Developer/MacOSX10.6.sdk
brew install pil

Easy solution:

1. install Homebrew
2. brew install pillow
