Not having a configuration program in PATH makes it completely useless. 2) You must use llvm-config for getting *all* flags: flags for the C++ preprocessor, flags for the compiler, flags for the linker, and libraries to link, by specifying to that command which "llvm engine" you need. I don't know exactly which engine you need ("jit" ?). 3) On my freshly compiled llvm-3.2svn, llvm-config will never link to that shared library, but to a lot of static "*.a" libraries. 4) So I guess that this shared library is all these *.a static libraries put into one big shared library. 5) That shared library cannot be used on Linux, because its name is not standard, and the "make install" command did not install it correctly. A shared library must follow a precise naming standard (for example libLLVM.3.2.0.so), and have many symbolic links (libLLVM.3.2.so libLLVM.so).

So there has to be _one_ node class for the generic node above (that can possess both attributes) that implements methods which resemble the tree algorithms. That way we could have a basic tree datastructure - if it is that simple. This basic datastructure can be inherited, overridden, etc. If the node class is aware of these both attributes (being root node of a tree and itself node in a tree at the same time) one can easily concatenate trees and that's what I wanted to show with my code above. (Sorry if I re-invent the wheel here) What you were out for, if I got you right, was only providing a datastructure for nodes and a separate class with code to handle them? Like pluggable algorithms on the same structures? (Hrm, regarding your timezone you must be somewhere near Autralia...)

Anynode.parent provides what I think your saying. (Aside, I think that separating the functionality from the node is the key of what I was trying to say. But that is a side issue.) Only in that the "tree" happens to be a directed graph that has one special node. I told you graphs were interesting. Having been born some time in the middle of the last century, I have no idea what an A-level is. I hope it's not painful. :-) and regards from me too! But if A-levels are what I think they are, I can recall thinking some 40 years ago, "calculus, as if I am ever going to need that in my life, ha!".

Consequently every node has to provide such functionality. I don't deem it necessary to distinguish between root and other nodes. The code is only once there anyway. It could even have helped in your case to "em-parent" (sorry, not a native English speaker) a node that you formerly assumed to be the root like NewNode.Left = RootNode RootNode = NewNode As interesting as it sounds, I'm probably not the right person to work on this.

I think you should concider using Glu.LookAt function, which should solve all your problems. I used it in collision project (attached) to follow the ball. You just set the camera with few parameters, and that's it! Please check the command help in Gambas. Simply speaking, you define eye point's (x,y,z position - no need for scale or translate), point you look at and point where the top of camera is (by changing it, you rotate the world in front of you), so I think that would solve it. See the attached example to see how I did it. Press F3 to see how it works.

"Any n-tree can be transformed into a b-tree where the left branch is the first child and the right branch is the first sibling." To be more correct I should have said "Any k-ary tree can be represented as a binary tree where the left branch is the first child and the right branch is the next sibling". The theory is in wikipedia here: http://en.wikipedia.org/wiki/Binary_tree#Encoding_general_trees_as_binary_trees. These binary trees have well known (Knuth and others) algrorithms for different actions to be used on the binary tree, insertions, deletions, (graft and prune), traversals in particular orders, searches, sorts etc etc. The application of a binary tree structure to suit a particular problem is a different matter.
