Mex files and C code

Hello,

May someone help me? I am testing a C code previously generated with Matlab-Coder (the code inside has a lot of operations with matrixes), I must to test it using a MEX file but matlab is showing me an error, like this:

>> mex MEX_ANAVS.c
Building with 'Microsoft Visual C++ 2012 (C)'.
Error using mex

Thank you so much in advance! :)

Did you ever get a solution for this? I'm having the same problem.

Hello! I give a answer for other people although you already solved this prob. I got a same problem when compiling the c code (like "file_name.c" ) with 'Microsoft Visual C++ 2012 (C)'. The problem is the compiler. just change the c code file name to cpp file.(file_name.c -> file_name.cpp) then it may works. :)

I hope it helps yo!
