27.8.3. Eigen
Header only linear algebra library with a mainline Buildroot package:
./build-buildroot --config 'BR2_PACKAGE_EIGEN=y' ./build-userland --package eigen -- userland/libs/eigen/hello.cpp
Just create an array and print it:
./run --eval-after './libs/eigen/hello.out'
Output:
3 -1 2.5 1.5
Source: userland/libs/eigen/hello.cpp
This example just creates a matrix and prints it out.
