[IGSTK-Users] Build Error with IGSTK 4.4 on Mac OS 10.7

[Matthew DiFranco]

Hi All,

I cannot build IGSTK on MacOS 10.7 (latest). I'm using CMake 2.8.7 and native compilers, and I've built ITK 3.20.1 and VTK 5.8.0 successfully. I'm using Qt 4.7.4, and also OpenIGTLink. In CMake, I am configuring for Eclipse Unix Makefiles.

Here's the error:

In file included from /Users/*******/Code/IGSTK_4-4/Utilities/SceneGraphVisualization/igstkSceneGraph.cxx:18:

Just to note, these errors come just after a whole lot of warnings from these two files:
/Users/*******/Code/ITK_3-20-1/Utilities/vxl/core/vnl/vnl_numeric_traits.h:390:28:
/Users/*******/Code/ITK_3-20-1/Utilities/vxl/core/vnl/vnl_math.h:86:36:

example warning:
warning: in-class initializer for static data member of type
      'const double' is a GNU extension [-Wgnu]
  static VNL_DLL_DATA const double e                VCL_STATIC_CONST_INIT_FLOAT_DECL(2.7182818284590452354);

Any help would be greatly appreciated!

Cheers,
Matthew
