Python PIL cannot locate my “libjpeg”

Question

I cannot use PIL because it cannot find my libjpeg!

First, I installed PIL default. And when I ran the selftest.py, it gave me:

IOError: dec         


        

Answer 1

I had the same issue. In my case, I need to set:

JPEG_ROOT="/usr/lib64/"

instead of:

JPEG_ROOT="/usr/lib/"

Good luck.

Answer 2

You could also try to use Pillow instead of PIL.

Pillow is a PIL fork to "foster active development of PIL". In versions 1.7.0 and 1.7.1 they made some changes to support multi-arch (see the changelog).

Answer 3

There at least 3 header sets that you will want to install. 1 more if you want to deal with Tiff's

freetype, libjpeg, zlib all of which will be in the following packages on CentOS:

== 32 Bit: zlib-devel.i386 libjpeg-devel.i386 freetype-devel.i386

== 64 Bit: zlib-devel.x86_64 libjpeg-devel.x86_64 freetype-devel.x86_64

As you did before you will want to edit the following variables in the setup.py file:

FREETYPE_ROOT JPEG_ROOT ZLIB_ROOT

Setting there values to /usr/lib or /usr/lib64 based on your platform. Once done you will most likely want to run

python setup.py build --force
python setup.py install

That will force rebuild all your lib for PIL and reinstall them raw.

Answer 4

You need the libjpeg headers as well, not only the library itself. Those packages are typically called something ending in headers or dev, depending on what distribution you have.

Answer 5

Today I was facing the same problem, and I've found the solution. Basically it involves remove the PIL, install lipjpeg through Fink and re-install the PIL.

I wrote an article telling step by step how to do that. If interesting check this out.
