I have read a lot of solutions to my problem but none helped. I tried clean, rebuild. Reinstalled visual 2010 and change from professional to ultimate. But still I dont know why I have this error. My project look like this: 1 Exe Solution to test my static library. 1 Dll Solution static library. Code which is converted to dll is using function from 1 lib called ClassificationFramework. I provided this lib as headers and cpp so basically source code. In Exe solution I linked my generated library + some other libs to run it + ClassificationFramework.dll. Everything works fine when I use Release but when I change to Debug (because I want to debug some stuff, I am tired of skipping debugger in release mode) I get this:

    2>Link:

When I build in Release I also got these warnings:

When i go to Debug->Windows->Modules i see that he cannot find those pdb files or something. How i can say him that those files are here here and here? I tried to run MSvisual as administrator but that too didnt help. I used microsoft server to load pdb files but also didnt help.

In VS2010 iterator debug level defaults to 2 in debug and is disabled in release. One of the dlls you are using probably has iterator debugging turned off in debug either because it was built in an older version of visual studio or they explicitly added the defines to the project.

Search for _ITERATOR_DEBUG_LEVEL and _SECURE_SCL remove them or set them appropriately in all projects and sources and rebuild everything.

_ITERATOR_DEBUG_LEVEL = 0 // disabled (for release builds)
_ITERATOR_DEBUG_LEVEL = 1 // enabled (if _SECURE_SCL is defined)
_ITERATOR_DEBUG_LEVEL = 2 // enabled (for debug builds)

In short you are probably mixing release and debug dlls. Don't linked release dlls in debug or vice versa!
