Cross-Compiling for arm32

Basic Compilation

Install GCC multilib and the arm32 cross-platform toolchain

sudo apt-get install gcc-multilib gcc-arm-linux-gnueabihf

Add the CC variable to the Makefile for gcc:

CC=arm-linux-gnueabihf-gcc

Compiling Libraries (seccomp)

Extra step required. We have to add the architecture, then update to get the packages:

sudo dpkg --add-architecture armhf
sudo apt-get update 

Finally, install libseccomp-dev for armhf:

sudo apt-get install libseccomp-dev:armhf
