Error Lnk2038: Mismatch Detected for '_Msc_Ver': Value '1600' Doesn't Match Value '1700' in Cppfile1.Obj

error LNK2038: mismatch detected for '_MSC_VER': value '1600' doesn't match value '1700' in CppFile1.obj

TL;DR; Recompile all your old static-linked .lib files with current-compiler (VS2012, in OP's case).

---

You are trying to link objects compiled by different versions of the compiler. That's not supported in modern versions of VS, at least not if you are using the C++ standard library. Different versions of the standard library are binary incompatible and so you need all the inputs to the linker to be compiled with the same version. Make sure you re-compile all the objects that are to be linked.

The compiler error names the objects involved so the information the the question already has the answer you are looking for. Specifically it seems that the static library that you are linking needs to be re-compiled.

So the solution is to recompile Projectname1.lib with VS2012.

You can link to older .lib files only if:

• If they are not static-linked, and come with an already compiled .dll file (or .exe file).
• Or if the two standard-libraries are binary-compatible (which they are not in OP's case).

Since you don't have the source code available (and therefore can't retarget libPolyFill), you're stuck using Visual Studio 2013.

C++ / Boost Filesystem - mismatch detected for '_MSC_VER': value '1700' doesn't match value '1600'

libboost_filesystem-vc110-mt-gd-1_51.lib is a library that has been built with VS 2012 (Also known as VC 11.0), as indicated by the vc110 in the naming convention. This library will not link properly with objects built with VS 2010 (also known as VC 10.0).

If you want to build your program with VS 2010, you'll need to get or build boost libraries for VS 2010.

Though not a perfect solution, I ended up creating a new project and reimporting all dependencies one after another, compiling in between to try and find the issue. After importing all libraries, the new project just worked. I then copied all of my code and compiled it in the new solution, which worked, so the issue has been resolved.

I saved a diff between the two project files, but couldn't find the issue (they are too different for me to make sense out of). Maybe someone with more experience can figure it out.
