I have generally managed to use gcc on mac, but now it is all broken. So annoying.
The Man clang does not handle nested functions even gnu99, so I brew installed the native arm gcc, which is a good start.
But it cannot find err.h and no amount of googling is helping me find it. It should be standard clib stuff.
Any clues welcome - what formulae or whatever it is called do I need to install?
