Ok. I checked my shaders_p.dll with dependency walker.
It tells me that the dll requires all openEXR DLL such
as(IlmImf,Half,Iex,etc..)
So I put all those libs into C:\Program Files\Autodesk\Maya2008\bin
folder..
and It worked. I supposed that the shader was linked statically but it is
not...
So how do I link statically...
answer: make sure OPENEXR_DLL is not defined in any of your projects
but I am not sure where I can find this "OPENEXR_DLL" part.
Could some one give me more detail of it, please?
Thanks.
Hiro

To be clear, is the question
- how do I link statically with OpenEXR on Windows?
answer: make sure OPENEXR_DLL is not defined in any of your
projects
or
- what DLLs need to be in the path for OpenEXR when used dynamically on
Windows?
short answer: all of the ones in the package, and zlib
longer answer: if you run depends.exe in the VS distribution,
open your plugin after running depends from the command line in
the directory your plugin resides. Any missing DLL's will be
identified and highlighted in red.

Excellent plug, Dave! ;-)
I'll forward this to Mr. Hiroyuki - haven't heard from him yet
subscribing to this ML and he's the one who submitted this particular
question over at my place (see bottom part of email). I'd very much
prefer to see this discussion happening in this ML as I expect others
using OpenEXR will benefit from it as well in the future (heck, I
might end up having to check the answers myself later on. ;-) )
After this email of mine, I expect Mr. Hiroyuki to pick up the
conversation and answer your question below on this ML (just to
prevent useless back-and-fro juggling by me).
Thanks,
Ger
