Cross compiling dlib for ARM on Ubuntu

Since I could not find any instruction to compile dlib for ARM (to use it e.g. on a raspberry pi) I decided to write one.

First, install all required packages:
sudo apt-get install libc6-armel-cross libc6-dev-armel-cross binutils-arm-linux-gnueabi pkg-config libx11-dev libatlas-base-dev libgtk-3-dev libboost-all-dev build-essential cmake libncurses5-dev gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf

Download dlib and upzip:

cmake -DCMAKE_C_FLAGS=”-O3 -mfpu=neon -fprofile-use -DENABLE_NEON” -DNEON=ON -DCMAKE_C_COMPILER=/usr/bin/arm-linux-gnueabihf-gcc -DCMAKE_CXX_COMPILER=/usr/bin/arm-linux-gnueabihf-g++ -DCMAKE_CXX_FLAGS=”-std=c++11″ –build –config Release ..


sudo make install
