Re: [Openexr-user] Windows Half.lib link errors

[James Burgess]

You sure you don't have OPENEXR_DLL defined? The editor will attempt  
to grey out the code that is ifdef'd out but it is easily confused. I  
suggest adding a #error or similar in half.cpp inside the appropriate  
#ifdef to prove you are getting the right defines. You must not have  
OPENEXR_DLL defined for a static build.
