How to debug QT-based C++ application that uses Matlab Engine API?

I am trying to debug a QT-based application (C++) that invokes the Matlab Engine API. As debugger I use cdb.exe from MS Visual Studio 2013 x64 within the QT Creator. The OS is Win7 x64.

Every time I start the debugger, the debugger chrashes. This behavior can be reproduced by creating a console application in QT and including the "engine.h" and adding the line:

Engine* ep = engOpen("");

in the main()-function.

Did you solved the problem ? I have the same trouble linking matlab's libraries, actually Qt recognise and compile the libraries but then the application crashes.

We had the same problem. Turns out that while running under the debugger the MATLAB DLLs could not be found but it was OK in release mode. We had to add "C:\Program Files\MATLAB\2015a\runtime\win64" to the PATH environment variable in the Run settings for the project.
