Title: Very Simple Debugger Issue
Post by: solarwind on June 21, 2008, 10:20:30 am
Hey all, I'm using Code::Blocks on winbloze and I have a simple debugger issue.

My program is as follows:

When I set the breakpoint and hit debug, Code::Blocks ignores it and continues execution until the end. It just jumps past the breakpoint... Is this supposed to happen?

make sure you build with debug settings on : project options : -g
and don't have the debug symbols stripped.

It IS building with -g:

Code
-------------- Build: Debug in Derek_Engine ---------------

mingw32-g++.exe -Wall -fexceptions  -g  -march=i686 -O3 -g    -c "C:\Documents and Settings\Administrator\My Documents\CppWorkspace\Derek_Engine\main.cpp" -o obj\Debug\main.o
mingw32-g++.exe  -o bin\Debug\Derek_Engine.exe obj\Debug\main.o

Process terminated with status 0 (0 minutes, 1 seconds)

Are you debugging in Constructors and Destructors?
See warning and example at the end of:

No, it's just a single man.cpp helloworld file.... Looks exactly as it is in the screenshot.

Try turning off the optimize option:
Project->Build options...->Compiler Flags -> Uncheck Optimize fully [-03]

You do realize that -O3 will probably eliminate/alter a lot of the code and, obviously, you won't be able to put breakpoints on it?

I totally did not realize that that could have been the issue. Thanks a lot! That fixed it!
