PIL JPEG mis-step

[darkblueB]

I got the Python Imaging Library from source, built and installed, on
Ubuntu 7.10, not realizing I could run a self-test first. libjpeg is
on the machine, but was not detected.. so no JPG encoder. I got the
dev-libjpg and rebuilt PIL. The self-test now shows JPG support.

but running setup.py install again seems to succeed, but still no
JPG :-(

fix ideas appreciated

Make sure that libjpeg62-dev is installed
'sudo apt-get install libjpeg62-dev'

Try run 'python setup.py build_ext -f' to force setup.py to rebuild
everything with JPEG. And 'sudo python setup.py install' should install
PIL with JPEG support.

It should work on Ununtu 7.10 (works for me at least).

However, if you want Tkinter support, you should edit setup.py and change
TCL_ROOT variable:
TCL_ROOT = '/usr/lib/tcl8.4', '/usr/include/tcl8.4'

And make sure that you have tcl/tk libraries/headers:
sudo apt-get install tcl8.4-dev tk8.4-dev

yes, that works

(the self test still gives misleading results ?)
but running some sample program works fine

thanks

You're welcome. To make self test inside source directory work you
probably should rebuild it inplace too.
python setup.py build_ext -f -i
