- (tetra)init;
to

HI all -
I want to be able to extend the NSOpenGLView class to have a ptr to
some ptr

Here's the tetra.h file

//indirection indexes to draw the tetrahedron

//rotation angles (x, y, z)

}
- (tetra)init;
- (float *)GetVertexPositions: (int)side :(int)idx;

When I try to compile this code I get these weird errors and warnings:

The errors don't make any sense to me as to why they're happening.
The
warnings neither, because the message names in the src are identical
in the
code.
So, any ideas why this isn't compiling, when it should??
Thanks, charles.
