error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in PCL.obj

[matjey]

hi,

i got many error in my project which is "error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '0' doesn't match value '2' in PCL.obj"

i think i already link my project correctly to their libraries.

it been a week i try to solved the errors but it seems no changes.
can someone guide me to solve my problem.

best regards.

Sounds like you are trying to link a 'Debug' executable with a 'Release' library or vice versa.

Debug exes must use debug libs, and release exes must use release libs.

Dear Disch..

Can you explain to me how I can change the exe release lib to debug..
i still new in this c++

[Disch]

I'm assuming you're using MS Visual Studio.

On the toolbar there should be a drop box that says "Debug". Click on that and select "Release", then rebuild.

thank you

The error is not in the source, you have been told to compile/link all libvraries/depedencies in release mode, not build one as release and others as debug.

Did you do that ? It should not be that hard ...

Value '2' means Debug mode and value '0' means Release for _ITERATOR_DEBUG_LEVEL:

dear modoran,

I already compile and build the code in release mode and there is no error. but it says cannot find the pdb files. I already extract the pdb file into directory and rebuild the solution but the program can function properly...

[modoran]

If you successfully build/link your app in release mode and it works, then do the same for a debug version (recompile all required libraries in debug mode this time).

Be very carefull when doing this - be 100% sure you not use the same output folders (Visual Studio usually fixed all of this for you, but external libraries may not ).
