I cannot seem to get Eigen 3.4.0 running in VS2010.

This is supposed to be so easy, but I cannot manage to do it.

  1. I downloaded the latest Eigen library, version 3.4.0, and unpacked the zip file.
  2. I opened VS2010, started a New Project --> Empty Project.
  3. Then I dragged the folder Eigen from eigen-3.4.0 onto the Project in Solution Explorer in VS2010.
  4. This resulted in the .h files being loaded into the Header Files folder in the Solution Explorer.
  5. I created a new .cpp file in the Source Files folder of the solution, with a very simple test script. (How to use Eigen in a C++ program?)
  6. I added the Eigen folder to the Include paths: Solution Explorer --> Right-click on Solution --> Properties --> Configuration Properties --> VC++ Directories --> Include Directories --> added D:\my folder\testingEigen\eigen-3.4.0\
  7. Also added this path to C/C++ --> General --> Additional Include Directories; then applied the changes.
  8. I did this for both the default setting of Win32 (Platform) as well as x64, both using Debug.
  9. I cannot compile successfully, the errors I get are as follows:

Now for Error 1, it seems to be a leftover issue maybe:

Code for error 1

Wildly guessing it is not important for what I want to use Eigen for, I have commented it out, but Error 2 and following still remain, for which the code is:

code for error 2

    Step 3 is wrong. Eigen is not part of your project, it's a third party library. The way to handle third party libraries is to install them where they want to be installed and then tell your project where you installed them, not copy them into your project. Commented Oct 11, 2024 at 5:05

    What version of C++ are you compiling for? Please also show the code you are compiling. Also don't show screen shots of code, include all code as text in the question. Commented Oct 11, 2024 at 5:38

    Just noticed that you are using VS2010. That is very old, that's probably the issue here. Time to upgrade. Commented Oct 11, 2024 at 5:39

    VS2010 ??? Wow, why not upgrade so you can use vcpkg instead? Commented Oct 11, 2024 at 5:45

    You will most likely have to install an old version of this library. You can't use a modern version with a 14+ year old compiler. Also remember that before VS 2015 the msvc compiler was incompatible across major versions. You likely can't use compiled binaries from any compiler other compiler version.
