Whenever I add a class I get "Undefined reference to WinMain"

oBFusCATed:
So you're trying to create a class without a name?

SuperBoi45:
Here's one with the name:

Can't reproduce this problem on Linux.
Can someone with a windows try it?

I suppose you're clicking OK twice in the two dialogs that are shown after this one?

Also I notice in the build log that it's not linking with my main.cpp. How would I add it?

Is the file main.cpp part of your project?
If not, add it.
If yes, try rebuilding the project and post the full rebuild log.

I could NOT duplicate the problem on my own Windows build of Git SVN 10030 (I do NOT think any of my patches would affect this issue).

Edit: Please include the Code::Blocks version information.

I suggest trying only one optimization code at a time. Note, it is likely unrelated to your problem; but, it is a bad idea to set all three of them in most cases only one of them works.
