It is possible to find which toolbox installed a given file?

Hello everyone,

I have a mex library that is linking (indirectly) the SDL2.dll library (https://www.libsdl.org/). If I try the mex library with a simple MATLAB/Simulink installation, everything works fine, but one user reported problems with an installation with almost all toolbox installed (version R2021b), as it seems that some toolbox is installing a vendored SDL2.dll in C:\Program Files\MATLAB\R2021b\bin\win64\SDL2.dll .

However, I do not know which toolbox installed this SDL2.dll file in that directory, there is some way to check which toolbox installed the SDL2.dll there? Thanks a lot in advance.

Hi Silvio,

I understand that you would like to know a way to find which toolbox installed a given DLL file. I believe this can be achieved using the Dependency Walker:

• https://www.dependencywalker.com/

Here is an article by MathWorks Support Team on “How do I determine which libraries my MEX-file or stand-alone application requires?” which might be helpful:

Hope it helps!
