Automatic selection is disabled in debug mode (/ Od); automatic selection in release mode maximizes speed (/ O2).

This speed maximization will lead to some code being streamlined and some code variables between before and after debugging in the Release version.

Inconsistencies, such as passing pointers, the address of the pointer may change. And when calling the third-party library, there is no way to get the dynamic or static library under the debug version, so you can only choose the release version. The main content of this chapter is how to set up the release version for debugging.

Analysis.

The setting in Release mode is mainly applied to the release of the software, which does not carry any debugging information, and the program has been optimized, and some statements have been optimized, so it can not be debugged. So just turn off optimization and allow debugging information to be generated

Modify:

1) attribute "" configuration property "" C _ Od + > > Optimization, optimization option: disabled (/ configuration)

The optimized code, some breakpoint debugged code has been optimized by the compiler and cannot be debugged.

2) property "" configuration property "" linker "" debug, generate debugging information: (yes / DEBUG), generate program database file: $(TargetDir) $(TargetName) .pdb
