This fixed it for me: https://aur.archlinux.org/packages/mfoc-hardnested-git/ "I was able to solve this by installing gcc-8 and setting it as default before compiling"

Hi,

The project moved to https://github.com/nfc-tools/mfoc-hardnested

If you feel that this problem should still be solved, reopen the issue there please. Thank you :)
