Setting up eigen math library with visual studio

Question

I have downloaded eigen and am trying to set it up with visual studio. My current file structure looks like this:

project:

src
Vendor

src:

main.cpp

Vendor:

Eigen

Here is my main.cpp file.

#include "../Vendor/Eigen/Core/Matrix.h"
#include <iostream>

int main()
{
    Vector3f v;
}

I am getting hundreds of errors. The first error is identifier uintptr_t is undefined in file atomic.

Edit: I opened the file "../Vendor/Eigen/Core/Matrix.h" and it seems to contain errors (some lines have squiggly red underlines).

Answer 1

It is only a guess depending on your source structure but you copied the wrong sources:

You need to copy the Eigen directory into your Vendor not the src which is in Eigen directory. And then try to:

#include <Eigen/Core>

The structure of Eigen

Eigen
|--> .gitlab
|--> Eigen / you need to copy this full directory
     |--> src      / I guess you copied this
     |--> Cholesky
     |--> ...
     ...
|--> bench
|--> ...
