MatLab C++ Shared Dll library initialization problem
显示 更早的评论
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;
First-chance exception at 0x00007FFA22761F08 in MatlabTest.exe: Microsoft C++ exception: xercesc_2_7::NoSuchElementException at memory location 0x000000E263EF4E48.

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,
It didn't work either.
I couldn't find any helpful answer on Matlab community or stackoverflow.
Do you have any idea why this is happening?
Thanks

I'm getting a similar error using MATLAB R2017a and VS2015. What should I do?

Had the same issue with MATLAB 2015b, 2016a, 2017b, Visual Studio 2015 and 2017. The program either crashed on "mylibInitialize()" or returned with an empty error message. Turned out that the program actually worked outside of Visual Studio, i.e. starting from command line. Solved it by setting Debugger Type to Managed Only in Visual Studio (Properties of Project -> Configuration Properties -> Debugging -> Debugger Type).

Yes, it works. But it disables debugging for unmanaged c++ :(

can you give me more details? my matlab is 2015a
if true
function [c] = myfittest(x, y)
c=x+y;
return;
end
end
my vs is 2013a（64bit）
myfittestInitialize() failed

Hello, have you solved this problem? I met the same initiallize failing problem as yours, so I wonder if you could give me some help, thank you!

Thank you very much! Your approach can solve this problem. My mabtlab ver is 2017b, and vs is 2017.

Problem is in usage of java in MATLAB.
Call
const char *args[] = {"-nojvm"};
const int count = sizeof(args) / sizeof(args[0]);
mclInitializeApplication(args, count))
instead of
mclInitializeApplication(NULL,0)
It solved the same issue for me.
