Thanks for your advice. We now have Midas installed on both our machines (remote machine-Rpi &
hostmachine-Centos).

> Yikes, the error is in the CRC library. The assembly-optimized crc32c function fails to build, and the

> BTW, "make linux32" will build an Intel 32-bit version (see "-m32" in "man gcc"). For ARM 32-bit

> For straight cross-compilation, look at the Makefile target "make linuxarm" (you will need to change

> For running MIDAS frontend on the Raspberry Pi 3, I build MIDAS on the Pi3 itself, the machine is big
