Visual Studio 2010 does not display debug information for local variables

Question

Visual Studio 2010 does not display debugging information for local variables. However, I have no problem viewing class variables. Are there any settings that I am missing?

This is a "debug" assembly.

I tried to go to Project Properties -> C ++ -> Optimization and disable all optimizations.

Answer 2

check to make sure the project is configured to export debugging symbols. These must be .pdb files. They contain debugging information for your code. I believe the setup is in the project-> Linker-> generate debug file.

For those who have problems with this problem ...

• download the patch from here http://archive.msdn.microsoft.com/KB2452649/Release/ProjectReleases.aspx?ReleaseId=5350
• Reboot the computer.
• rebuild your project

and, most likely, everything will be fine then ....

Answer 4

If you experience this with the switch-case statement, just add a conditional empty command, like

if(true) ; 

for testing purposes. It seems that some older versions of Visual Studio suffered from an error in which a missing setting of any kind (at that time, if ...) in one case displayed locales during debugging in the following cases, invisible.

If you are using Visual Studio 2010 Express (for example, I was), this fix is ​​by getting Service Pack 1, which you can get by running Windows Update.

Answer 6

Always include only compatible debug libraries:

I came here because Visual Studio 2010 did not display debugging information for some local variables in the opensv 2.4.2 library. In Mat _InputArray::getMat(int i) const I had to see several variables, but k and vv were missing. (and I got an exception in cv::_interlockedExchangeAdd when getMat (mistakenly) returns only empty matrices.) In any case, the problem was that I included (as a library in PATH for DLLs and as #pragma comment ) as debug libraries , and release libraries. This seems to have caused the problem. Everything worked well after including only debug libraries.

Answer 7

I was able to fix this problem in VS2015 by turning on the option> Debugging> General> Use native compatibility mode.

MSDN says that "when this option is selected, the debugger uses its own Visual Studio 2010 native debugger instead of a new native debugger." We are building with Intel C ++ 12.1, which is based on VC10, so it makes sense!
