I want to use newtxtext and newtxmath fonts in combination with siunitx. I also need bold math so I added the bm package as described in: Sans-serif bold math with newtxmath

Now I am facing font shape line warnings:

LaTeX Font Warning: Font shape `OT1/ntxtlf/sb/n' undefined

Does anyone know a solution? Especially which characters are subsituted?

Thank you!


\documentclass[12pt, a4paper, twoside]{book} 
\usepackage[libertine, vvarbb]{newtxmath}
\usepackage{bm} %Bold math

    Why are you loading the option libertine if your text font is newtxtext? – Ulrike Fischer Nov 21 '17 at 9:29
