MATLAB: Code Blocks configuration for Calling Matlab code from C/C++

clinking

Hey Everybody,
I was just trying to go through a simple matlab tutorial for calling matlab code from c/c++ code and Im getting an error:
code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    #include "engine.h"
    int main()
    {
        printf("Hello world");
        Engine *ep;
        ep = engOpen("");
        engEvalString(ep, "x=(1:1:10);");
        engEvalString(ep,"y=x.^2;");
        engEvalString(ep, "plot(x,y);");
        engClose(ep);
    return 1;
    }
Build log(Added new lines to help readability):
mingw32-gcc.exe -Wall -g -Weffc++ -std=c++0x -I"C:\Program Files\MATLAB\R2012b\extern\include" -c C:\Users\Public\Documents\C++\CToMatlab\main.c -o obj\Debug\main.o

Error:
undefined reference to `engOpen' undefined reference to `engEvalString' undefined reference to engEvalString undefined reference to `engEvalString' undefined reference to `engClose'
I know that this is a linking error but not sure what I'm failing to link.
Any help would be apreciated.

GCC compiler for "MATLAB Externals" is not supported on windows platform. You must use the Microsoft compiler.
...but, unfortunately in CodeBlocks IDE there is a parsing command-line for Microsoft compiler bug.
I think you should use Visual Studio Express. Everything is much easier to configure. Do not forget to specify the path to the libraries and header files to MATLAB extern:
matlabroot\extern\lib\<platform>\microsoft
matlabroot\extern\include\
