- Make sure that you are NOT using GCC 4.0. That means those export lines in your .bash_profile file that you needed to get MySQLdb working now need to go away.
- I used libjpeg 7 (http://www.ijg.org/files/jpegsrc.v7.tar.gz), even though I doubt it was necessary.
- Before installing PIL but after installing libjpeg, I changed the “JPEG_ROOT = None” line in my setup.py file to “JPEG_ROOT = libinclude(”/usr/local”)”

Has anyone found a solution? (I will post if I figure it out…)

I also tried the otool trick, but it shows no dependency at all on libjpeg! During PIL compilation, the output correctly says that Jpeg support is present.

First of all, my system is running python in 32bit mode with the same configuration as Stefan’s shown above.

The key to fixing this was noticing that the libraries in /opt/local were always getting included and taking precedence over any other libjpeg libraries in the system (same with zlib). First I uninstalled all libjpeg related ports, and then installed libjpeg from here: http://www.ijg.org/files/jpegsrc.v7.tar.gz

The output from rebuilding PIL showed “ok” for support of all the functionality, but when I imported _imaging I got an error. But it was a new error! Symbol not found: _deflate.

After discovering that it related to zlib, I uninstalled zlib from ports and freetype. I got zlib-1.2.3, which installed fine from source. Then I tried the newest version of freetype, but it wouldn’t build. The readme from PIL suggests freetype >= 2.1.3, so I chose 2.1.10. It built and installed fine from source.

With all my libraries now in /usr/local, I rebuilt PIL (using libconfig(”/usr/local”) for jpeg, freetype and zlib), and everything went fine. Installed PIL, fired up python interpreter and imported _imaging, and no error!!!

I tried doing the same myself but it did not work for me… actually I got into more trouble than the one I started from!

Now building PIL creates MacOS 10.3 binaries

$ sudo python2.5 setup.py build
running build
running build_py
creating build/lib.macosx-10.3-i386-2.5
copying PIL/__init__.py -> build/lib.macosx-10.3-i386-2.5
copying PIL/ArgImagePlugin.py -> build/lib.macosx-10.3-i386-2.5
copying PIL/BdfFontFile.py -> build/lib.macosx-10.3-i386-2.5
(…)

and then fails with:

cc1: error: unrecognized command line option “-Wno-long-double”

I believe there may be confusion between Snow Leopard’s own Python and the one I installed from http://www.python.org . I could not use the default one because I need my code to work on 2.5 . Any advice?

I appreciate any help.

I could’nt manage to compile PIL (Imaging) with the last version of gcc (4.2). So I forced the compilation with gcc 4.0 by modifying the alias in /usr/bin

WARNING: This has only been tested on my macbook pro running Snow Leopard. Please only follow this if you fully understand what it does.

Forcing gcc to use 4.0 version :
sudo rm /usr/bin/gcc
sudo ln -s /usr/bin/gcc-4.0 /usr/bin/gcc

Getting back to the 4.2 version of gcc :
sudo rm /usr/bin/gcc
sudo ln -s /usr/bin/gcc-4.2 /usr/bin/gcc

I found, running one of the gcc command from the Imaging installation, that it made the following error : “libjpeg.a, file is not of required architecture”. So I googled a bit about that problem and found out that I should install the last version of libjpeg forcing the architecture.

That’s what I did :
1) After detaring the jpegsrc.v7.tar.gz file and running ./configure, I edited “Makefile” and found the line :
LDFLAGS =
and replaced it by :
LDFLAGS = -arch i386 …
Then make and make install.

2) The lib was installed in /usr/local/lib so, back to the PIL installation : I detared “Imaging-1.1.6.tar.gz”, went into the new directory and edited “setup.py”. I replaced
JPEG_ROOT = None
by
JPEG_ROOT = “/usr/local/lib”

3) Then I ran the “python setup.py build” and “python setup.py install” commands and it was working !

Good luck !
