Hello,
I'm stuck on a nasty error. I've been on it for 2 hours and my nerves are going to explode!

Here is the log:
Quote: "------ Build started: Project: Triple, Configuration: Debug Win32 ------
Linking...
libcpmtd.lib(xdebug.obj) : warning LNK4098: defaultlib 'libcmt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library

Triple - 3 error(s), 1 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
"


Some info on the program:
2 simple classes
uses string library
doesn't make use of darkGDK functions yet

It's the first time I see this error and my program is really simple at the moment. I really don't understand how this bugger got here.

Any guidance as to where and what kind of error I should look for would help me. Or even just translating what the compiler is trying to tell me (the only thing I understand is that the problem involves libraries).

This usually happens when using STL containers.

To fix it:

Project->!Project_Name! Properties...->[+]Configuration Properties->[+]C/C++->Code Generation

Change the Runtime Library to /MT instead of /MTd

Click OK.

It should compile fine now.

Perfect! Thanks alot!
I would have never found hehe.

Instead of starting a new post I will add a question here:

I programmed in C++ under Linux at school and our teachers taught us to declare a class in a .h but to define the functions in a .cpp with the same name.
When defining the function in the .cpp we would go:

void ClassName::FunctionName() { ... }

but VC++ doesn't like that. Whenever I tried that syntax he gave me errors and I ended up defining all my functions in the .h file.

Is there another better way or is this just how I'm going to have to program in windows?

That syntax is correct. What was the error?

Did you make sure the .h file was included?
