How can export a mex function from sources into a regular c++ function (shared library)) ?

How do I export mex functions (having the sources) into c++11 code (ie., without mex/matlab dependency) ?
Can I do that with the Library Compiler App [1] to create a shared c++ library (as source) ?
If not, how to adapt the mex functions into a regular c++11 ?

To clarify, you have mex functions and you want those translated to a C++ library? Assuming the source code is either C or C++, then you simply need to compile/link into a DLL. You can use any compiler/linker to do this ( vis studio, gcc, etc). If the C/C++ code relies on MATLAB libraries, you can use the mbuild command.

I actually want to export MEX sources into regular c++ sources, not the binaries in that case.
The same way we can export m functions into c/c++ sources (without matlab dependency).
The MEX sources (a custom matlab function written in c/c++) are relying on many MEX functions (eg., mxIsStruct, mexErrMsgTxt , mxGetField, mxGetPr, mxGetDimensions, mxGetClassID ...). If I transform code into another that does not depend on those mex functions, it would be what I call regular c++ code.

There is no way to generate C code for the MEX functions being used in your MEX sources... but the primary purpose of the MEX functions ( mxIsStruct, etc. ) is to all MATLAB to call your your C++ code. If you are planning to use your C++ code outside of MATLAB, then you no longer need these MEX functions. It sounds to me like you will have to modify your C++ code to get rid of all of the usages of MEX functions.
