[vtk-developers] OpenGL extension "NV_shader_buffer_store" can not be supported?

[qwcbeyond]

the extension “GL_EXT_direct_state_access”  have another problem.
I use  extensions->ExtensionSupported("GL_EXT_direct_state_access") to check
if it is supported. It return true. But when I use 
extensions->LoadExtension("GL_EXT_direct_state_access") ,it report an error.

vtkOpenGLExtensionManager (00000000086B6F50): Attempting to load
GL_NV_shader_buffer_store, which is not supported.

ERROR: In D:\home\src\vtk-5.8.0\Rendering\vtkOpenGLExtensionManager.cxx,

vtkOpenGLExtensionManager (00000000086B6F50): Extension
GL_EXT_direct_state_access could not be loaded.
