Title: wxSmith tutorial help needed
Post by: DarthVega7 on February 25, 2015, 06:54:22 pm
Hello,

I'm currently trying to complete this tutorial:  http://wiki.codeblocks.org/index.php?title=WxSmith_tutorial:_Using_wxPanel_resources

But I'm getting this error:

You don't have a definition of this method in your code 99.9% sure.
If you have then inspect the compiler's log if the source file is really being compiled.

What do you mean definition of method?  I'm sorry I'm new to programming.

Good books on C/C++ explain what is a declaration and what is a definition.
If you don't know what these two terms mean you'll suffer a lot. So go reading.
