Installation

Run:

$ npm i eigen.cxx

And then include Eigen.h as follows:

// main.cxx
#include <Eigen.h>  // or, Eigen/Eigen

int main() { /* ... */ }

Finally, compile while adding the path node_modules/eigen.cxx to your compiler's include paths.

$ clang++ -I./node_modules/eigen.cxx main.cxx  # or, use g++
$ g++     -I./node_modules/eigen.cxx main.cxx

You may also use a simpler approach with the cpoach tool, which automatically adds the necessary include paths of all the installed dependencies for your project.

$ cpoach clang++ main.cxx  # or, use g++
$ cpoach g++     main.cxx
