[Insight-developers] ITK Shared Build with VS2012

[Bruno Ronzani]

Hey back,

I'm still stuck on it ! It's been days...

Here is a sample code : http://codepad.org/jXtJdRnK

But look, this is from itksys/Configure.h ... why "#if 0" ?!

Since there is no dll_export, i'm not surprised that ITK is always
built statically :(

/******/

/* Setup the export macro.  */
#if 0
# if defined(_WIN32) || defined(__CYGWIN__)
#  if defined(itksys_EXPORTS)
#   define itksys_EXPORT __declspec(dllexport)
#  else
#   define itksys_EXPORT __declspec(dllimport)
#  endif
# elif __GNUC__ >= 4
#  define itksys_EXPORT __attribute__ ((visibility("default")))
# else
#  define itksys_EXPORT
# endif
#else
# define itksys_EXPORT
#endif

/*****/

Thanks for you help,

Bruno
