Hello,
I generated a very basic DLL following the instructions (https://de.mathworks.com/help/coder/gs/generating-c-code-from-matlab-code-using-the-matlab-coder-project-interface.html) only changing for DLL instead of LIB. The file "distance.m" looks like this:
function res = distance(a, b)
res = b-a;
end
Then I tried to include it in my Visual Studio 2022 Project which just consist of
#include <iostream>
#include "distance.h"
int main()
{
distance(1, 2);
}
I followed the instructions here (https://learn.microsoft.com/en-us/cpp/build/walkthrough-creating-and-using-a-dynamic-link-library-cpp?view=msvc-170) to include the directory.
When I build the project, it gives me the Linker Tools Error LNK2001: unresolved external symbol "__IMPORT_DESCRIPTOR_distance" (and following LNK1120).
I already tried it with a basic DLL generated in VS with no problems at all. I only fail with DLLs generated with MATLAB Coder.
Can someone help me with this?
Thanks in advance!
Philipp

I think that is the problem. I'll try it with the VS compiler as soon I got VS installed and let you know the results.

Sorry for the late answer, I had some license issues with VS.
Using the VS compiler for the DLL fixed the problem.

Hello Philipp,
There's an example in our documentation that walks through the steps for integrating a DLL generated by MATLAB Coder with a Microsoft Visual Studio project. Have you given that a try ?
