HDRI 32 bit TIF to EXR

[senatorbard]

Hello,

I am a big rookie on Linux, so if you could be so kind, please be detailed in your explanations.

I'm trying to convert a 32 bit TIF to 32 bit EXR. I have ubuntu and I have downloaded Image Magick through Synaptic Package Manager.

I understand that you must configure Image Magick to HDRI to convert 32 bit images. It looks like I may have to build from scratch?
I'm nervous about doing this - I tried building once and the only way to get image magick working again, I had to reinstall my OS. Is there any way to get a package download that already has HDRI activated?

If not, could you please give me detailed description about configuring HDRI. If I do build, what directory is the best place to build? How do I uninstall an unsuccessful build? I need step-by-step. Sorry for being such a newb.

Thank you so kindly - I appreciate any help you can offer!

See http://www.imagemagick.org/script/advan ... lation.php for advanced installation instructions.

To enable HDRI, type

• cd ImageMagick-6.5.4-1
  ./configure --enable-hdri
  make
  sudo make instal

Please note that I believe IM will only handle openEXR "half" format (16-bits). But please confirm this with the IM folks.

To enable HDRI, type

• cd ImageMagick-6.5.4-1
  ./configure --enable-hdri
  make
  sudo make instal

Do I need to download the zipped version or can I use the one that came from syanptic?
sorry - I'm really new at this stuff. Could use just a few more details. Should I be in a certain directory when I install and use image magick?

I typed in

./configure --enable-hdri
make


I got the following errors:

We have a patch for the problem you reported. Look for it in ImageMagick 6.5.4-2 beta available by tomorrow. Thanks.
