Eigen Template

This is a simple C++ project template for starting work using the Eigen library for linear algebra.

Prerequisites

Make sure that you have CMake installed. For most systems, you can install it using the default package manager.

If you are on a Mac and have Homebrew installed, run the following command:

brew install cmake

On Ubuntu it can be installed by running

sudo apt install cmake

On other Linux distributions it should work similar using their respective package manager.

Usage

The usage of this template is very simple.

First clone it using the following command:

git clone --recursive https://github.com/Zollerboy1/eigen-template.git

This creates a directory called eigen-template, which you can enter like this:

cd eigen-template

To see if everything is working correctly, create a build folder, enter it, and build the template project using the following commands:

mkdir build
cd build
cmake ..
make

You should now have an executable which can be run like so:

./src/main

This should print the following output:

1 2 3
4 5 6

If it doesn't, feel free to open an issue on this repository and tell me what error(s) you are getting where and which OS/hardware you are using.

Otherwise you can now start to write your own program that uses Euler.

Put source files (i.e. .h and .cpp files) into the src folder. In this folder you already see some source files (you can delete foo.h and foo.cpp but you have to remove foo.cpp from the first line of the src/CMakeLists.txt file as well). Whenever you add a .cpp file, you also have to add it to the list of source files inside the add_executable command in src/CMakeLists.txt (just separate the file names using a space), otherwise it won't be compiled when you invoke cmake and make.
To build the project when you made some changes, you go again into the build folder and invoke the cmake .. and make commands from above.
