The course staff will post answers to frequently asked questions about assignment 3 here.  Feel free to add to this page yourself if you've got information to share with the rest of the class.  Remember, the quickest way to get a response from a TA is to post to cs148-win0607-staff@lists.stanford.edu

== 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.
