[Openexr-devel] Re: Header Files

[Paul Schneider]

Hi, Richard,

eLut.h and toFloat.h are automatically generated by the make system.  
They populate lookup tables with machine-dependant data.  You'll need 
to do this step manually in CodeWarrior.

You need to compile eLut.C into an app called "eLut" and run it; it 
will dump these values to stdout (or SIOUX if you're building CFM in 
CodeWarrior), and then you can save the output as eLut.h.  Same deal 
for toFloat.h.  I've done this by starting from CodeWarrior's "C++ 
Console" stationary, and it wasn't too hard.  Note that eLut.C and 
toFloat.C are just for these apps; don't compile them into your EXR lib.

zlib.h is part of the open-source zip library, which you'll also need 
to build.  This should be available here:

http://www.cdrom.com/pub/infozip/zlib/

I don't know if they have a CodeWarrior project; I just built my own.

How soon do you need this?  I was actually thinking of posting a 
CodeWarrior project in a few days.  I had a little trouble with some 
posix headers not supported in MSL (dirent, etc), but was able to work 
around it.  I actually think some of these dependancies have been 
removed for the OpenEXR branch.  I'm not sure if I'll be able to get to 
this before next week (or before somebody else ports it to 
CodeWarrior!), so let me know if you need it sooner and I can help you 
if you get stuck again.  Also, I'm not sure of the licensing issues 
involved; ie if I could include a built zlib in the distribution, or if 
clients would be required to download and build their own.

Thanks,
Paul
