PIL problem after installation

[Lad]

I installed PIL under Linux but now when I try it I get the error:

decoder jpeg not available
How can I correct that problem?

Thank you for help

if you built PIL yourself, the setup script told you how to fix this.

- make sure you have right libraries installed (see the
"prerequisites" section in the README)

- run setup and read the BUILD SUMMARY report carefully

- if the setup script cannot find a component, you'll have to edit
the setup.py file and set the appropriate ROOT variable. see in-
structions in the setup.py file for details.

if you got a binary release, complain to the distributor.

Probably the jpeg library - libjpeg is not present on your system.
Search Google for it, then download and install it. Try
http://rpmfind.net also to find it:

http://rpmfind.net/linux/rpm2html/search.php?query=libjpeg&submit=Search+...

But Fredrik's advice is very good - whenever installing a software
package, make sure to read the installation guide, release notes, etc -
carefully, and then do accordingly. This can save you a lot of time and
rework.

Fredrik,
Thank you for the reply.
So I did the following:

1.
I downloaded jpeg (from ftp://ftp.uu.net/graphics/jpeg/ ) source
libraries( file jpegsrc.v6b.tar.gz) and installed them. Now in
/usr/local/lib I have the following files: cjpeg
,djpeg,jpegtran,rdjpgcom and wrjpgcom
2.
I opened setup.py file in Imaging 1.1.5 directory
and changed JPEG_ROOT =None into
JPEG_ROOT = "/usr/local/lib/"

3.ran python setup.py build_ext -i
but it still says

*** JPEG support not available

What did I wrong?
Can you please help?
Thank you
L.

I had similar problems a couple of months back when I was teaching
myself Tkinter and PIL. I wrote up my experiences here:-

If you look at the section on Images you will see how I eventually
solved it (with bucket loads of help from this forum)

Good luck

cjpeg, djpeg etc are executables, not libraries. if you have them under
/usr/local/lib, something's not quite right.

to save some time, I suggest looking for a jpeg-dev or jpeg-devel
package in the package repository for your platform.

Hello Fredrik,
Thank you for your reply.
I installed jpeg-devel package and now selftest.py worked!
But I want to use PIL in my Python program( Django) running under
Apache. What permissions must I use for which files?
Thank you very much for your help.
