The easiest way is to use "find /usr -name <header>" and then use the
directory that is the base for <header>.

Also, I couldn't find anywhere in my system (including ARM and AArch64
directories) the following headers:

* malloc/malloc.h (my malloc.h is directly that the include path, ie,
no "malloc/")
* ndir.h / sys/ndir.h / mach/mach.h / mach-o/dyld.h / histedit.h
(seems to be Apple specific?)

If you're moving your source from Apple to Linux you *will* need to
make it portable, and that includes choosing headers, defining macros,
etc.

I *did* find:

* cxxabi.h (it was directly on the include path, at
/usr/arm-none-eabi/include/c++/5.3.0/cxxabi.h, but you may have to add
that to -I)
* valgrind/valgrind.h (but only on my x86 include path, you may have
to install valgrind-dev:armhf)

Also, the error:

/usr/bin/ld: cannot find -lz

shows me that you don't have Zlib installed, you'll need that.
