RE: Fwd: Question about openEXR-1.6.1

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
