    <p>I recently wrote an article on how to get PIL, django, libjpeg to work nicely alongside Snow Leopard</p> <p><a href="http://appelfreelance.com/2010/06/libjpeg-pil-snow-leopard-python2-6-_jpeg_resync_to_restart/" rel="noreferrer">http://appelfreelance.com/2010/06/libjpeg-pil-snow-leopard-python2-6-_jpeg_resync_to_restart/</a></p> <p>I'll copy it in here for you too.</p> <p>If you don’t have this download it first.</p> <blockquote> <p><a href="http://www.ijg.org/files/jpegsrc.v7.tar.gz" rel="noreferrer">http://www.ijg.org/files/jpegsrc.v7.tar.gz</a></p> </blockquote> <p>go into your shell environment and untar by running the following</p> <blockquote> <p>tar -zxvf jpegsrc.v7.tar.gz<br /> cd jpeg-7</p> </blockquote> <p>then run</p> <blockquote> <p>sudo make clean<br /> sudo CC="gcc -arch i386”"./configure --enable-shared --enable-static<br /> sudo make<br /> sudo make install</p> </blockquote> <p>Next get PIL and untar it</p> <blockquote> <p><a href="http://effbot.org/downloads/Imaging-1.1.6.tar.gz" rel="noreferrer">http://effbot.org/downloads/Imaging-1.1.6.tar.gz</a><br /> tar -zxvf Imaging-1.1.6.tar.gz<br /> cd Imaging-1.1.6</p> </blockquote> <p>If you already have PIL I would recommend running</p> <blockquote> <p>sudo rm -Rf build</p> </blockquote> <p>to clean any existing builds, this has caused me loads of errors and gray hairs!</p> <p>in your settings.py file run find JPEG_ROOT</p> <p>amend it so it looks as follows</p> <blockquote> <p>JPEG_ROOT = libinclude(“/usr/local”)</p> </blockquote> <p>Next move onto the build</p> <blockquote> <p>sudo python setup.py build</p> </blockquote> <p>if libjpeg is successfully installed you should be able to run python selftest.py without any errors relating to “jpeg”</p> <blockquote> <p>sudo python setup.py install</p> </blockquote> <p>if all has worked successfully you should be able to enter your python interpreter by executing python in your command line and also do the following:</p> <blockquote> <p>import PIL<br /> import Image<br /> import _imaging</p> </blockquote> <p>without any errors.</p> <p>Just to triple check I have a simple jpeg on my desktop.</p> <blockquote> <p>image = Image.open(“/Users/MyName/Desktop/myimage.jpeg”)<br /> image.save(“/Users/MyName/Desktop/test.jpeg”)</p> </blockquote> <p>should work without errors </p>

    1. CO+11111!!! following the instructions above (taking care to wipe out pre-existing libjpeg install first) was the final successful solution for me after many failures. For others I also got the `ImportError: No module named _imagingmath` when running selftest.py, but it doesn't seem to matter because at last I can `import _imaging` without the _jpeg_resync_to_restart error

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
