I want to use OpenEXR in my application, however after building all the needed libraries (and even trying with pre-compiled downloaded from the internet).

Everything goes fine, but when I compile a project that use OpenEXR I get

unresolved external symbol "__declspec(dllimport) union half::uif * _toFloat" (__imp_?_toFloat@@address@hidden@@A)  

I've googled the issue and added as well the OPENEXR_DLL directive, the Half.lib is in the additional dependencies list of the project.

Hi Jerome,

    I don't have a Windows machine to verify but looking at the half.h file, I guess you will need to define HALF_EXPORTS to get the symbols exported.

Cheers
