make: gdkglcontext.h error unknown type name 'GdkGLDrawable'

[pinging2000]

Hi,

I'm having a compile error with the 'gdkglcontext.h' when running 'make' tool.

The 'GdkGLDrawable' has no declaration in any h files.

The file 'gdk\gdkgltypes.h' has declaration for '_GdkGLConfig', '_GdkGLContext' and '_GdkGLWindow' that exists in other h files except for '_GdkGLDrawable' which not does exist anywhere.

Any clue?
Thanks
-r.

'gdk\gdkgltypes.h'
typedef struct _GdkGLConfig GdkGLConfig;
typedef struct _GdkGLContext GdkGLContext;
typedef struct _GdkGLDrawable GdkGLDrawable;
typedef struct _GdkGLWindow GdkGLWindow;
