MatLab C++ Shared Dll Library Initialization Crash

Question

I am using Matlab 2013a and Visual Studio 2013. I am trying to use MatLab compiled dll from a C++ console application. My simple Matlab test dll and console application is compiled for 64bit machines (I made sure they are 64bit via dumpbin). I also have correct version of MCR installed on my machine (even if it's not necessary).

I setup my compiler using "mbuild -setup" command.

I compile my .m file using this command line: "mcc -v -W cpplib:mylib -T link:lib myFunc" successfully.

In my console application, I include these libraries: mylib.lib, mclmcrrt.lib, mclmcr.lib, libmx.lib, libmat.lib and use the libraries in this path "C:\\Program Files\\MATLAB\\R2013a\\extern\\lib\\win64\\microsoft"

When I debug my program, it successfully initializes MCR using this call: "mclInitializeApplication(NULL, 0)" but when I call "mylibInitialize()" in order to initialize my library, program crashes. It doesn't even throw an axception therefore I cannot handle it using try/catch block. It gives unhandled exception and access vialoation error message.

These are sample debug output messages I got;

The program '[12952] MatlabTest.exe' has exited with code 0 (0x0).

I installed MCR to another machine and tried to run this console application. I got the same result.

I tried Loren's Vigenere example too, http://blogs.mathworks.com/loren/2011/02/03/creating-c-shared-libraries-and-dlls/#respond

It didn't work either.

Do you have any idea why this is happening?

Thanks

Answer 1

It seems problem is MATLAB and Visual Studio version mismatch. If I use MatLab 2016a with Visual Studio 2013, there is no problem and everything works perfectly.

Answer 2

I had the similar problem with Matlab2017 + VS 2015. Probably there is some conflict with java used by MATLAB.

I've fixed it by using

const char *args[] = {"-nojvm"};
const int count = sizeof(args) / sizeof(args[0]);
mclInitializeApplication(args, count))

instead of

mclInitializeApplication(NULL,0)
