Build fails on Raspbian 64-bit

[heisenberg2980]

I am trying to run epk2extract on my Raspberry Pi running Raspbian 64-bits.

I followed the steps for Ubunty/Devian to install build dependencies, and when executing the build I am getting this error:

pi@raspberrypi:~/scripts/epk2extract/epk2extract-master $ ./build.sh
