Boost mex compilation error > SharedMatrix

Hello, I use matlab a alot but not much C. I'm trying to use SharedMatrix ( http://www.mathworks.com/matlabcentral/fileexchange/28572-sharedmatrix). I downloaded the Boost library and tried to install/compile it with:

mex -v -O -win32 -I'C:\Program Files\boost\boost_1_51' SharedMemory.cpp

The exact output I get is:

*************************************************************************** 
  Warning: Neither -compatibleArrayDims nor -largeArrayDims is selected.  
           Using -compatibleArrayDims. In the future, MATLAB will require 
         the use of -largeArrayDims and remove the -compatibleArrayDims  
         option. For more information, see:

Could you please

1. Explain the error to me.
2. How do I fix this? I have used code that supposedly many people have successfully used. Why would these errors come up on my machine?

Answer 1

[James Tursa]

The supplied lcc compiler is a C compiler only, not a C++ compiler. You will not be able to compile cpp files with lcc. You need to install and select a C++ compiler to compile cpp files.

[Jan]

In addition the LCC shipped with Matlab is really old and contains serious bugs e.g. for (u)int64. Even installing a modern LCC downloaded from the net is a good idea, but modifying the mexopts.bat file is not trivial. Better install a supported, modern and efficient compiler.

[Evan]

Ah brilliant. May I ask which modern C++ compiler I should get? Also, I assume I change the compiler on Matlab with the command "mbuild -setup", yes?

Thank you

EDIT 1: Actually, I do have Visual Studio 2010, and I've changed the compiler to it via "mbuild -setup" but I keep getting the same message on lcc. What is going on?

EDIT 2: Ok, I see that "mex -setup" is the one I should have used instead of "mbuild -setup". But now I am actually getting errors on compilation. I will post this on a new question because the content is bigger than I should post on a comment window.
