I created a shared library for interfacing matlab functionality from a C++ project. My build environment is as follows:
  • Matlab R2018a
  • Visual Studio 2017
  • Windows 10
When initializing the library the application crashes.
I can confirm that using the "-nojvm" option as suggested here: https://de.mathworks.com/matlabcentral/answers/286624-matlab-c-shared-dll-library-initialization-problem avoids the crash.
Yet this is not a viable solution in my case as I have to integrate a library that uses matlab figure handles. Using "-nojvm" therefore leads to a runtime error:
Error using figure
This functionality is no longer supported under the -nojvm startup option. For more information, see "Changes to -nojvm Startup Option" in the MATLAB Release Notes. To view the release note in your system browser, run web('http://www.mathworks.com/help/matlab/release-notes.html#btsurqv-6', '-browser').
I have attached a small example project that reproduces the crash and interfaces a simple function:
function createPlot()
fh = figure;
plot(1:10, 1:10);
saveas(fh, 'test', 'png');
end

Hi Dominik
I understand that you are trying to create a shared library for interfacing matlab functionality from a C++ project.
I would suggest you to use a different version of visual studio or matlab for this as there might be some mismactch of the versions.
