I have been not able to correctly link my static debug library to link correctly. Everything works fine in the release mode however.
In debug mode I get the following error :
Error LNK2038 mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in Engine.h.obj
Error LNK2038 mismatch detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't match value 'MD_DynamicRelease' in Engine.h.obj
I have created a Type.External Module to wrap my third party library and placed it in the source folder along with the game and the editor modules of my plugin.
I need this because I want to be able to step through the code of the external library after hitting a breakpoint in order to detect and fix issues.
However, I can’t, for the life of me, find a way so that I can step through the code in the external library in debug mode. Any and all help on this will be highly appreciated !
So after playing around with this for the whole day I have had some success by building a release library with debug information and optimizations disabled. But if there’s a correct way of linking actual Debug libraries I am still interested in hearing about possible solutions. Thanks !
Can you explain how you got it to work? I’m facing the same issue.
Got same issue long time ago. If I remember correctly, you have to rebuild your external library and change a setting in the Visual Studio’s project settings.
So open your library solution, access the project properties, go to C/C++ > Code Generation and find the line “Runtime Library”. Here you have the choice between :
- Multi-threaded (/MT)
- Multi-threaded Debug (/MTd)
- Multi-threaded DLL (/MD)
- Multi-threaded Debug DLL (/MDd)
“MDd_DynamicDebug” means “Multi-threaded Debug DLL (/MDd)” is used.
“MD_DynamicRelease” means “Multi-threaded DLL (/MD)” is used.
This setting should match the value in your error message. So you should use “Multi-threaded DLL (/MD)” when compiling your library (if I understood correctly).
More informations are provided here : c++ - LNK2038: mismatch detected for 'RuntimeLibrary': value 'MT_StaticRelease' doesn't match value 'MD_DynamicRelease' in file.obj - Stack Overflow and here : /MD, -MT, -LD (Use Run-Time Library) | Microsoft Docs
Just found that you also have to make sure if you have
_DEBUG defined it must be changed to
/MD libs and vice-versa for
/MDd libs or you will continue to get the link error.
