Subdir rule
(Project Properties window)
*.prj\CONFIGURATION\Subdir rule
By default, object files and the executable file built by the project are located in a subdirectory of the project base directory. This is given the same name as the target configuration, for example, ...\Debug.
Use this setting to change this subdirectory rule. Right-click to see the available values.
If you do not use a subdirectory, all object files for all configurations are saved in the same location and so RealView Debugger assumes that all configurations build the same objects.
