Unable to install Python Imaging Library

[peter.mosley]

A few weeks ago I asked for advice about which GUI toolkit I should
learn, and receved several helpful answers. In the end I went with
Tkinter. This was because a) it was already installed on the machines
I am most likley to use, b) it is cross platform, and c) it was not as
complex as PyGtk - which I tried and was totally unable to decipher.

I am now at the point of trying to import the Python Imaging Library,
and I have reached a total standstill. I downloaded a copy of Python
Imaging Library 1.1.5 Source Kit from the site
http://www.pythonware.com/products/pil/. There did not seem to be any
prebuilt binaries suitable for my system (Python 2.2/Fedora Core 1), so
I loaded the source code.

The instructions said to try 'python setup.py install', followed by
more detailed instructions 'If you prefer to know what you're doing'. I
do prefer to know what I'm doing, but couldn't understand the following
instructions. So I tried the simple route, but it failed with the
output shown below.

I have absolutely no idea how to proceed. Can anyone point me in the
right direction to get over this hurdle?

the setup procedure has determined that your Python has been built with
Tkinter, and that Tcl/Tk libraries and include files seem to be available, but
the compiler cannot find them, for some unknown reason.

have you tried installing the Tcl and Tk development libraries ? (usually
tcl-devel and tk-devel)

if you have, look for lines similar to the following

--- using Tcl/Tk libraries at /usr/local
--- using Tcl/Tk version 8.4

in the output from the setup script, and make sure that you have the Tcl/Tk
libraries and include files at that location (look in the lib and include directories).

Thanks for that reply.

I hadn't tried installing the Tcl and Tk development libraries -
because I had no idea these that these were necessary (or that they
even existed!). My first attempt to do so was a total failure, as I
downloaded the RPM files from http://rpmfind.net, but immediately
entered a dependency hell. My next attempt was a little more thought
out - I looked for the appropriate files on some Fedora Core 1
distribution discs, and to my surprise found them. To my even greater
surprise, I could load these without problems and then the PIL install
ran smoothly.

So thanks to your hint I have got there. Much appreciated.
