Installing C library but Permission Denied?

Question

I'm trying to install this C library and I'm running:

sudo make  -f makefile.osx

but my terminal is telling me:

make: /usr/lib: Permission denied

My root user is enabled and my password is correct and everything, does anyone know what's wrong?

Please show what command `make` was running when that error occurred and also show the exact directory ownership and permissions. — kaylum, Jul 19 '16 at 23:58

Welcome to Mac OS X 10.11 El Capitan and the SIP — System Integrity Protection — feature.

You can't install software in /usr/lib — not even if you're root.

You may install software under /usr/local, or under /opt.

See the discussion in Can Mac OS X El Capitan run software compiled for Yosemite that expects libraries in /usr/gnu64/lib?. The short answer is "No — you can't run software that was compiled to expect libraries in a sub-directory of /usr that is not under /usr/local". And the answer for "can I install libraries in /usr/lib?" is equally emphatically "No". The question has some links to resources.
