Controlling Flux2D from Matlab

Hi,

 

I am trying to set up communication between Matlab (version 2019a) and Flux2D (as a server, using version 2019.1). I have been able to do this succesfully in the past with older versions of Flux2D (12.3). However, for the new version, I found that a library needs to be loaded for this in Matlab using the following command: 

 [notfound,warnings]=loadlibrary(strcat(installFlux,'\Bin\dll\win64\',fluxmp,'.dll'), strcat(installFlux,'\Api\win64\include\flux_mp_matlab.h'));

I have made sure that the variable 'installFlux' is set correctly (manually checked the result of strcat). Also, I am using MinGW as a C/C++ compiler in Matlab (recommended by Matlab). However, when I try to run the command above, I get some errors:

Do you have any idea what is causing this problem? Is MinGW the right compiler for loading this library, or do I need a different one?

 

Thanks in advance for the reply.

 

Best regards,
