How can I compile C++ codes using DLL files created in Matlab in the IDE Code::Blocks?

*Steps I have taken before compiling:

- Created a Matlab C-S Function Project

- Added the .dll file (libtest.dll) and all other associated files (libtest.lib, libtest.h,etc) created in Matlab previously to the project

- Added a C++ file, mcctest.cpp, I created to use a function in the .dll file above

- Made sure all the library files from Matlab's "extern/lib" and "sys/lcc/lib" are linked in COde::Blocks

- Made sure to add the paths "extern/include" and "sys/lcc/include" in the Code::Blocks compiler settings

- Set up Code::Blocks to work with Matlab's LCC compiler*

When I finally run mcctest.cpp:

#include <iostream>
#include "libtest.h"

using namespace std;

int main() {

      // Initialize the MATLAB Compiler Runtime global state
      if (!mclInitializeApplication(NULL,0))
      {
          std::cerr << "Could not initialize the application properly."
                    << std::endl;
          return -1;
      }

      // Initialize the libtest library created in Matlab
      if( !libtestInitialize() )
      {
          std::cerr << "Could not initialize the library properly."
                    << std::endl;
          return -1;
      }

double dat[1] = {4};

mwArray x1(1,1,mxDOUBLE_CLASS);
x1.SetData(dat,1);

mwArray x0;

int out = 1;

funcx(out,x0,x1);

//cout << a[];

}

These are the error's I get:

I get almost exactly the same errors when I run "mbuild mcctest.cpp libtest.lib" in Matlab using the LCC compiler:

*Anyone ever ran into the same problem before? Anyone found a solution?

Looking forward to some clue! Thanks!*

You may want to correct your question because the word S-function is misleading. From what I can tell by looking at your code, you are simply writing a driver application to call into the DLL generated by MATLAB Compiler, which has nothing to do with S-functions.

I would recommend that you follow the tutorial Integrate C Shared Libraries from the MATLAB Compiler documentation to understand exactly what header files and libraries are required.

I have edited the question. Thanks for the suggestion and the link!
