Problems installing library

[NyleAlliss]

I am new to C++ and have tried installing this package from the Binary.Package.Windows.x64.zip file the same way this video shows how to do it (https://www.youtube.com/watch?v=or1dAmUO8k0). When I try to run debug one of the examples:

#include <matplot/matplot.h>
#include <random>

int main() {

    using namespace matplot;

    auto x = linspace(0, 3 * pi, 200);
    auto y = transform(x, [&](double x) { return cos(x) + rand(0, 1); });

    scatter(x, y);

    show();

    return 0;
    }

I get lots of errors and warnings. If I do not add the library to the linkers I get fewer errors, but I'm still getting 8 errors linked to a filename.obj file. As well as 24 warnings from header files. The errors are below:

I'm pretty sure I haven't installed this correctly and I have basically no understanding of adding packages in cpp, but I would ideally like the package to be added to the executable upon building the program as explained in the video I linked. I also haven't installed any of the dependencies, but I believe they are only required when building from source. But I may be wrong. Sorry to ask what probably seems like a silly question but I have spent all day trying to get this to work, any help is appreciated.

What your error error LNK2019 is saying is that your executable could find the header #include <matplot/matplot.h> (the declarations) but could not find the external symbols (the definitions). In other words, it seems like the library is not linked.

If you're using CMake, you can try some of the other options, like automatic download with CPM: https://alandefreitas.github.io/matplotplusplus/integration/cmake-targets/cmake-with-automatic-download.html

In other build systems, the only options is to link the library manually.

Hello, I think I have a similar issue trying to setup matplot++ for Visual Studio 2019. The error above can be solved by linking nodesoup.lib to the project.

However, after that I got a bunch of linker errors. In half of them it says that there is a value missmatch for RuntimeLibrary, I double checked that, in my project I also use Multi-threaded DLL (/MD) RuntimeLibrary. It would help out a lot if you can suggest how to resolve this problem.
