The book 'Beginning OpenGL Programming' was made by the founder/s of this site as I understand it, so I figured what better place to ask :)

The question is about a font programming recommended by the book called glFont2. There is a .h and a .cpp, which the directions with glFont2 say to compile with my project, so they're in my project...

And glfont2.h generates compiler errors :(

on this line:

		//Height is the same for now...might change in future		size->second = (int)(header.chars[header.start_char]->dy *			header.tex_height);

The error: base operand of '->' has non-pointer type 'glfont::GLFont::GLFontChar'

I assume this compiles successfully for others, else it wouldn't be included in the book, so why does it generate an error for me? :(

size->second = (int)(header.chars[header.start_char]->dy * header.tex_height);

size->second = (int)(header.chars[header.start_char].dy * header.tex_height);

Quote:"->dy" should be ".dy"... I think.

When I change it to that, there is a new error of 'second has not been declared'

Well.... I'm using Dev-C++ to compile, could that have anything to do with it?
