Why the code doesn't break at the breakpoint in code blocks

Question

I followed the instruction from this video to run the code line by line:

http://www.youtube.com/watch?v=6CGH9Z19dS8

However, after I pressed F8, it just ran without going to the breakpoint(I couldn't see the yellow triangle). In addition, I also tried "attach to process", and it was the same.

Did I miss anything?(btw, there are multiple files in my project, but I guess that won't be the problem, right? cuz I could do this easily in VS studio. Perhaps, I am not that familiar with codeblocks)

Thanks for help!

Answer 1

Even if you have had marked -g compiler option the problem may be spaces in path to the project file. Moving to place with no spaces in path solved the problem in my case. See that: http://wiki.codeblocks.org/index.php?title=Debugging_with_Code::Blocks#Path_with_spaces
