### Warning:  Using unoptimized lapack ###
### Warning:  Using unoptimized lapack ###

I want to be using an optimized version of lapack - how do I do this?

Answer 1

I suppose that you previously installed lapack and blas libraries with

apt-get install libblas-dev liblapack-dev

If you have problems, you can upgrade this libraries. Try it!
