Hi David,

If you are not sure about MPX hardware support, you can find out the processor model with the following commands:

Linux - cat /proc/cpuinfo | grep model
Mac   - sysctl -n machdep.cpu.brand_string

If the processor code is one of the following - i7-6xxx, i7-6xxxT, i5-6xxx, i5-6xxxT, i3-6xxx, i3-6xxxT - it is definitely part of the 6th Generation Intel processors and it supports MPX. Otherwise, it does not.

Whether the hardware is MPX enabled is irrelevant for the build process. GCC 5.1 and higher will generate the MPX specific instructions, which will be turned into nop's at runtime if the processor is not MPX enabled.
