Mostly, C programmers have the same issues with CLASSPATH, -jar and so
on, none of which were designed to solve these kind of things, but you
get used to it. It's just a matter of having the information stored in
your head ;-) Starting out your question by saying you don't want to use
something generally tends to put off the people that wrote it, but I
understand your frustration, so...

You are linking with the wrong libraries or have set up the project
incorrectly in some way. If you have the examples working, then copy the
settings from there. HOwever:

1) Create a new project and don't change the library settings;
2) Get a test to work;
3) Then add your existing things;
4) You have turned off MSVCRT, which is the C runtime - you won't get
very far without that ;-)
