libmwi18n.dll, libmx.dll, libmat.dll could not be found when building code with slbuild

Hello everyone,

I'm trying to build a standalone executable file from simulink model with the command slbuild. This runs via Matlab without errors, but when I run the executable file externally (I mean double click on it), I get the error that some .dll files (libmwi18n.dll, libmx.dll, libmat.dll) could not found which are also in the matlab installation folder (matlabroot/bin/win64). How should create the executable file so that it also runs externally in another working folder?

I use this code for building and running:

% Build and run simulations

simulationStopTime = simulationStopTimeArray(1);

slbuild(models(modelNumber))

for k = 1:length(simulationStopTimeArray)

for iRepeat = 1:2

tic

eval(['!' modelName ' -tf ' num2str(simulationStopTimeArray(k))])

durationOfBuiltCodeRSim(k) = toc;

end

end

I would appreciate any tips on how to fix this error. Thanks.

Hi Semih,

I understand that you are getting error “libmwi18n.dll, libmx.dll, libmat.dll could not be found “ while building a Simulink model with ‘slbuild’ command.

These errors may arise because of outdated build folders. This may lead the ‘packNGo’ to not find the DLL files.

To resolve the issue , I suggest you the following steps :-

• Delete the 'slprj' folder and everything else from the build folder including the MEX files
• Rebuild the model to generate the new MEX files, makefile and other build files.

I hope this resolves the issue you were facing.
