I'm trying a library could Eigen. There, I'm having a problem with running the library, in which the cmd doesn't recognize the directory. I've noticed that the files which Dense is leading for, are not a c++ files but just files, soo I thought I need to change that.

Eigen I believe is all header files

#

I don't think you would have to convert it to cpp files.

Where are the Eigen files stored relative to the code project you are working on?

# 
#include <Eigen/Dense>
#

this should be good enough as long as you pass in the correct directories to the compiler

#

The error I'm getting that it doesn't exist

#

and I saw that all the files in Eigen are just files

#

They're not cpp

#

I mean by the includes

hard rapids
#

Ok - did you link the correct directory for the compiler?

#

They just can't work

how are you compiling the code?

#

What command do you use to compile/build your code?

lament karma
#

It's like that: g++ -I "C:\grand\program files..."

#

That's one of the things that I needed to do

hard rapids
#

ok so g++ -l"C:\some\path\to\your\code" is that the full command?

lament karma
#

I'll show you all

#

Sorry I'm taking the time

#

I just had some problem

#

Wait one second

  1. Show me the path to where you extracted/compiled the Eigen package
  2. Show me the full g++ command that you use to compile the code

#

these are the two

hard rapids
#

you need to add -I "C:\Users\grand\OneDrive\....\eigen-3.4.0" to your second command

#

just like the first one

lament karma
#

after the g++?

hard rapids
#

yes

lament karma
#

Okay

#

Thank you

#

It worked

#

That's how you do that

hard rapids
#

np 🙂 - in general you have to tell the compiler where the library you want to link to is. And thats how you do it

lament karma
#

I understand
