Re: [Openexr-devel] Cross-compiling problem for iOS

[Piotr Stanczyk]

hmm interesting ... this is the first post I've seen on iOS deployment. 

I presume lines 58 and 59  of half.cpp looks like this to you:

58 HALF_EXPORT_CONST unsigned short half::_eLut[1 << 9] =
59 #include "eLut.h"

HALF_EXPORT_CONST should be defined in half.h as 


#if defined(OPENEXR_DLL)
    #if defined(HALF_EXPORTS)
        #define HALF_EXPORT __declspec(dllexport)
    #else
        #define HALF_EXPORT __declspec(dllimport)
    #endif
    #define HALF_EXPORT_CONST
#else
    #define HALF_EXPORT
    #define HALF_EXPORT_CONST const
#endif


Are you able to check to see if your code is in the right part of this macro 
expansion?

Piotr
