You first need to go to the directory with the ./configure script.
Normally this is the top directory unpacked from a source tarball.

So the instruction
   ./configure --enable-hdri
in
   http://www.imagemagick.org/script/high-dynamic-range.php
is most probably a modification instruction for
   http://www.imagemagick.org/script/install-source.php
where you can see ./configure after the step
   cd ImageMagick-6.9.3

Well, the base instruction seems slightly outdated.
Currently the file
   http://www.imagemagick.org/download/ImageMagick.tar.gz
unpacks to directory
   ImageMagick-6.9.3-4

So my proposal for modified instructions is:

   cd $HOME
   mkdir image_magick_dir
   cd image_magick_dir
   wget http://www.imagemagick.org/download/ImageMagick.tar.gz
   tar xzf ImageMagick.tar.gz
   cd ImageMagick-6.9.3-4
   ./configure --enable-hdri
   make

(Be prepared that ImageMagick-6.9.3-5 or -6 emerges instead of -4.)

If this succeeds with no demotivating error message at the end, then
you should de-install the Debian binary version before you perform
the step

   sudo make install

After that, the command
   identify -version
should report HDRI. At least according to

I did not try out anything of this. Good luck to the trailblazers !


Have a nice day :)

OOPS. I didn't notice that the instructions were assuming a tarball installation. I just used the debian aptitude install application. That answers one question but I still have a problem. The instructions say that after the installation that one can run the following to check the installation:
    identify -version and get a Features list that includes HDRI
Unfortunately, the only feature that shows up is DCP Modules Open MP. No HDRI. The ImageMagick installation must be there or identify wouldn't work at all. In addition I have used several convert functions successfully. Any suggestions.
