Raspberry Pi setup

On a Raspberry Pi install:

sudo apt-get install build-essential chrpath diffstat gawk libncurses5-dev texinfo pkg-config

Install OpenCV for

sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libxvidcore-dev libx264-dev
sudo apt-get install libgtk2.0-dev
sudo apt-get install libatlas-base-dev gfortran
sudo apt-get install libopencv-dev python-opencv

Install OpenAlpr

sudo apt-get install openalpr
sudo apt-get update && sudo apt-get install -y openalpr openalpr-daemon openalpr-utils libopenalpr-dev

Setup camera driver

sudo modprobe bcm2835-v4l2

add to /etc/modules

Set interface for camera in "Raspiconfig"

Cross complie instruction for Raspberry PI

on Ubuntu 18.04 install the toolchain for arm

sudo apt-get install build-essential
sudo apt-get install g++-arm-linux-gnueabihf
sudo apt-get install gdb-multiarch

Set the file system of Raspberry Pi ("sysroot") in the make file E.g.

CXX = arm-linux-gnueabihf-g++ --sysroot=/home/jose/Documents/Utility/YoctoRPi/sysroot

Install gtest

follow the instruction from : https://github.com/google/googletest and compile for ARM and for x86_64 and set the folder in "UnitTest/Makefile" e.g.

ifeq ($(ARCH), arm)
DIR_GTEST_LIB     = /home/jose/Documents/Utility/googletest/lib/arm
CPPFLAGS += -DRASP
else
DIR_GTEST_LIB     = /home/jose/Documents/Utility/googletest/lib
endif
