Mismatch Detected for RuntimeLibrary

Question

I downloaded and extracted Crypto   in C  cryptopp  I used Visual Studio Express 2012 to build all the projects inside  as instructed in readme   and everything was built successfully  Then I made a test project in some other folder and added cryptolib as a dependency  After that  I added the include path so I can easily include all the headers  When I tried to compile  I got an error about unresolved symbols   To remedy that  I added C  cryptopp Win32 Output Debug cryptlib lib to link additional dependencies  Now I get this error   Error   1   error LNK2038  mismatch detected for

I had this problem along with mismatch in ITERATOR DEBUG LEVEL  As a sunday-evening problem after all seemed ok and good to go  I was put out for some time  Working in de VS2017 IDE  Solution Explorer  I had recently added copied a sourcefile reference to my project  ctrl-drag  from another project  Looking into properties- C C   Preprocessor - at source file level  not project level - I noticed that in a Release configuration  DEBUG was specified instead of NDEBUG for this source file  Which was all the change needed to get rid of the problem

Issue can be solved by adding CRT of msvcrtd lib in the linker library  Because cryptlib lib used CRT version of debug

This is already answered in comments  but since it lacks an actual answer  I m writing this    This problem arises in newer versions of Visual C    the older versions usually just silently linked the program and it would crash and burn at run time   It means that some of the libraries you are linking with your program  or even some of the source files inside your program itself  are using different versions of the CRT  the C RunTime library    To correct this error  you need to go into your Project Properties  and or those of the libraries you are using   then into C C    then Code Generation  and check the value of Runtime Library  this should be exactly the same for all the files and libraries you are linking together   The rules are a little more relaxed for linking with DLLs  but I m not going to go into the  why  and into more details here    There are currently four options for this setting    Multithreaded Debug Multithreaded Debug DLL Multithreaded Release Multithreaded Release DLL   Your particular problem seems to stem from you linking a library built with  Multithreaded Debug   i e  static multithreaded debug CRT  against a program that is being built using the  Multithreaded Debug DLL  setting  i e  dynamic multithreaded debug CRT   You should change this setting either in the library  or in your program  For now  I suggest changing this in your program   Note that since Visual Studio projects use different sets of project settings for debug and release builds  and 32 64-bit builds  you should make sure the settings match in all of these project configurations   For  some  more information  you can see these  linked from a comment above     Linker Tools Warning LNK4098 on MSDN  MD   ML   MT   LD  Use Run-Time Library  on MSDN Build errors with VC11 Beta - mixing MTd libs with MDd exes fail to link on Bugzilla Mozilla   UPDATE   This is in response to a comment that asks for the reason that this much care must be taken    If two pieces of code that we are linking together are themselves linking against and using the standard library  then the standard library must be the same for both of them  unless great care is taken about how our two code pieces interact and pass around data  Generally  I would say that for almost all situations just use the exact same version of the standard library runtime  regarding debug release  threads  and obviously the version of Visual C    among other things like iterator debugging  etc    The most important part of the problem is this  having the same idea about the size of objects on either side of a function call   Consider for example that the above two pieces of code are called A and B  A is compiled against one version of the standard library  and B against another  In A s view  some random object that a standard function returns to it  e g  a block of memory or an iterator or a FILE object or whatever  has some specific size and layout  remember that structure layout is determined and fixed at compile time in C C     For any of several reasons  B s idea of the size layout of the same objects is different  it can be because of additional debug information  natural evolution of data structures over time  etc    Now  if A calls the standard library and gets an object back  then passes that object to B  and B touches that object in any way  chances are that B will mess that object up  e g  write the wrong field  or past the end of it  etc    The above isn t the only kind of problems that can happen  Internal global or static objects in the standard library can cause problems too  And there are more obscure classes of problems as well   All this gets weirder in some aspects when using DLLs  dynamic runtime library  instead of libs  static runtime library    This situation can apply to any library used by two pieces of code that work together  but the standard library gets used by most  if not almost all  programs  and that increases the chances of clash   What I ve described is obviously a watered down and simplified version of the actual mess that awaits you if you mix library versions  I hope that it gives you an idea of why you shouldn t do it

I downloaded and extracted Crypto   in C  cryptopp  I used Visual Studio Express 2012 to build all the projects inside  as instructed in readme   and everything was built successfully  Then I made a test project in some other folder and added cryptolib as a dependency    The conversion was probably not successful  The only thing that was successful was the running of VCUpgrade  The actual conversion itself failed but you don t know until you experience the errors you are seeing  For some of the details  see Visual Studio on the Crypto   wiki        Any ideas how to fix this    To resolve your issues  you should download vs2010 zip if you want static C C   runtime linking   MT or  MTd   or vs2010-dynamic zip if you want dynamic C C   runtime linking   MT or  MTd   Both fix the latent  silent failures produced by VCUpgrade     vs2010 zip  vs2010-dynamic zip and vs2005-dynamic zip are built from the latest GitHub sources  As of this writing  JUN 1 2016   that s effectively pre-Crypto   5 6 4  If you are using the ZIP files with a down level Crypto    like 5 6 2 or 5 6 3  then you will run into minor problems   There are two minor problems I am aware  First is a rename of bench cpp to bench1 cpp  Its error is either    C1083  Cannot open source file   bench1 cpp   No such file or directory LNK2001  unresolved external symbol  void   cdecl OutputResultOperations char const   char const   bool unsigned long double     OutputResultOperations  YAXPBD0 NKN Z    The fix is to either  1  open cryptest vcxproj in notepad  find bench1 cpp  and then rename it to bench cpp  Or  2  rename bench cpp to bench1 cpp on the filesystem  Please don t delete this file   The second problem is a little trickier because its a moving target  Down level releases  like 5 6 2 or 5 6 3  are missing the latest classes available in GitHub  The missing class files include HKDF  5 6 3   RDRAND  5 6 3   RDSEED  5 6 3   ChaCha  5 6 4   BLAKE2  5 6 4   Poly1305  5 6 4   etc   The fix is to remove the missing source files from the Visual Studio project files since they don t exist for the down level releases   Another option is to add the missing class files from the latest sources  but there could be complications  For example  many of the sources subtly depend upon the latest config h  cpu h and cpu cpp  The  subtlety  is you won t realize you are getting an under-performing class   An example of under-performing class is BLAKE2  config h adds compile time ARM-32 and ARM-64 detection  cpu h and cpu cpp adds runtime ARM instruction detection  which depends upon compile time detection  If you add BLAKE2 without the other files  then none of the detection occurs and you get a straight C C   implementation  You probably won t realize you are missing the NEON opportunity  which runs around 9 to 12 cycles-per-byte versus 40 cycles-per-byte or so for vanilla C C
