Where can I download err.h?

Was a solution to this ever found?

You should already have err.h as /usr/include/err.h, but the build failure may have more to do with building in an Arduino context -- the Arduino platform is based on C++, not C, which impacts the build setup in many ways.

Are you building with the included makefile? heatshrink.c is the main source for the command line tool, which really doesn't make sense to build for an Arduino, but has built without issue on macOS. I haven't tried since Yosemite, though.

If that's not enough to get you unstuck, I need more details about how you're trying to build.
