Hi all,

I am trying to build POVRay 3.7.33 for Window under VS2008. When I tried to
rebuild all POVRay project, when linking step, the system told me that
IlmImf.lib can't be find.
I want to know the role of IlmImf.lib in POVRay project?

Thanks,
Wise

Given you are inexperienced building software, you might want to consider 
using the binary betas of POV-Ray 3.7...

The source code is really only provided for experienced developers and it is 
going to be extremely time consuming and frustrating to build the beta from 
source if you do not have the necessary experience.

The library IlmImf you did not build or place properly is part of OpenEXR.

It's a library used in turn by the OpenEXR library. It's not part of the POV-Ray
source distribution (due to license issues I guess), so you need to get them
from Industrial Light & Magic:

    http://www.openexr.com/

Alternatively, you can disable OpenEXR support by adding/changing the following
line in ...\vfe\win\syspovconfig.h

    #define OPENEXR_MISSING 1

and remove the references to the following libraries from the povray project:

    IlmImf.lib
    half.lib
    imath.lib
    iex.lib
    IlmThread.lib

(For the debug or 64-bit version, the names may slightly differ.)

This will leave your POV-Ray version unable to handle the EXR high dynamic range
file format, but otherwise fully functional, including the Radiance HDR file
format.

Thanks all of you warm support!

I understand it now.

Thanks,
