Python PIL : IOError: decoder jpeg not available

The first thing I check when I got this error was to check if libjpeg was installed. 
Lets try this

  1. sudo apt-get install libjpeg libjpeg-dev  
  2. sudo apt-get install libfreetype6 libfreetype6-dev   

download  jpeg source

  1. tar -xzvf jpegsrc.v8c.tar.gz  
  2. cd jpeg-6b/  
  3. ./configure  
  4. make  
  5. sudo make install  


So download  Python Imaging Library 1.1.7 Source Kit (all platforms) 

The after run the setup.py install, check if the support was ok

  1. --------------------------------------------------------------------  
  2. *** TKINTER support not available (Tcl/Tk 8.5 libraries needed)  
  3. --- JPEG support available  
  4. --- ZLIB (PNG/ZIP) support available  
  5. *** FREETYPE2 support not available  
  6. --- LITTLECMS support available  
  7. --------------------------------------------------------------------  

If not, in setup.py in PIL I had to change the path of :

  1. JPEG_ROOT = None  
  2. ZLIB_ROOT = None  

to
  1. JPEG_ROOT = libinclude("/usr/")  
  2. ZLIB_ROOT = libinclude("/usr/")
