[Image-SIG] Mac support for PIL

[Paul Ross]

Thanks, and sorry, what I meant to say is that PIP is really easy to install on windows but a bit of a trial on Mac.

There are loads of blog entries around, which perhaps reflects the trouble that people are having. Many of these entries are highly version specific and have a less than unity probability of success (I tried three before I managed to get things working). Judging by the comment on most blogs other people are in the same boat as I.

FWIW this is what eventually worked for me:
Based on: http://rezmuh.sixceedinc.com/2009/04/setting-up-pil-with-libjpeg-on-mac-os-x-leopard.html

I got and installed MacPorts-1.8.2-10.6-SnowLeopard.dmg from:
http://distfiles.macports.org/MacPorts/

Then in Imaging-1.1.7:

In setup.py  changed the JPEG_ROOT to:
JPEG_ROOT = "/opt/local/lib/libjpeg.dylib"

Then:
sudo python setup.py build --force
sudo python setup.py install

I would not guarantee this will work for others!

Thanks for the help and thanks for such a great product as PIL

Regards,

Paul.
