VS Express Linkage Problems
If you are using Visual Studio Express 2005 and obtain linkage warnings involing libST functions that look like this:
Linking... layout.obj : error LNK2019: unresolved external symbol "public: class STSceneNode * __thiscall STSceneNode::GetNext(void)" (?GetNext@STSceneNode@@QAEPAV1@XZ) referenced in function "void __cdecl destroyDrawables(class STSceneNode *)" (?destroyDrawables@@YAXPAVSTSceneNode@@@Z) layout.obj : error LNK2019: unresolved external symbol "public: class STSceneNode * __thiscall STSceneNode::GetFirstChild(void)" (?GetFirstChild@STSceneNode@@QAEPAV1@XZ) referenced in function "void __cdecl destroyDrawables(class STSceneNode *)"
It's probably because VS Express hasn't correctly loaded the libst library dependencies from our project/scolution files (all this works fine in the full blown version of Visual Studio). You'll need add libst.lib as an additional dependency in your assignment3 project.
Go into the project properties > Linker > Input and adding libst.lib to the list of 'Additional dependencies'.
(thanks to Paolo Bezoari for reporting this)
Control characters under Unix/Mac
If you're developing on a non-Windows machine and see control characters (empty boxes) in your output, make sure to remove the carriage return character ('\r') when you read from the text file. Under Windows, opening files in text mode should deal with this automatically, but other OSs won't.
