Hello,
I have two c++ lib file which I want to link in my Managed c++ application. While liking it gives 56 link error and I am able to figure out how to resolve these errors. Here are few error details:

Quote:
error LNK2005: "private: static class std::locale::_Locimp * __cdecl std::locale::_Getgloballocale(void)" (?_Getgloballocale@locale@std@@CAPAV_Locimp@12@XZ) already defined in msvcprtd.lib(MSVCP110D.dll)

error LNK2005: "public: __thiscall std::exception::exception(class std::exception const &)" (??0exception@std@@QAE@ABV01@@Z) already defined in MSVCRTD.lib(MSVCR110D.dll)

error LNK2005: __calloc_dbg already defined in MSVCRTD.lib(MSVCR110D.dll)

error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in ManagedWrapper.obj

Please let me know if anybody know how to solve this problem.

What I have tried:

I ignored LIBCMTD.lib and MSVCRTD.lib from Properties->Linker->Input in CLR project but still giving link error.

I changed runtime library to "Multi-threaded Debug (/MTd)" in Properties->c/C++->Code_Generation for CLR project but I get error "'/clr' and '/MTd' command-line options are incompatible"

There is no such thing as "Managed C++", for a long time now. It has been superseded by C++/CLI. Is it what you are using? :-)
And the section "What I have tried" is designed to show us what you really tried, not just for mentioning it. How about a comprehensive code sample?

Please see my comment to the question.

C++ is unique language in this respect. You can use regular P/Invoke .NET API, but it's really beneficial to use mixed-mode projects where you can freely mix managed + unmanaged. Please see:
Calling Native Functions from Managed Code[^],
Using C++ Interop (Implicit PInvoke)[^],
Using Explicit PInvoke in C++ (DllImport Attribute)[^],
Native and .NET Interoperability[^].
