Compile Z/IP Gateway for Raspberry pi 3B+
=========================================

1. Install dependency
sudo apt-get install cmake gcc bison flex xsltproc libssl1.0-dev libusb-1.0-0-dev

2. Build
$ mkdir build 
$ cd build 
$ cmake -DRPI3PLUS=Y ..
$ make package
Find the Debian .deb package
$ ls zipgateway-7.00.0-Linux-rpi3plus-armhf.deb



Cross compilation of Z/IP Gateway for Raspberry Pi 3B+ Raspbian GNU/Linux 9.3 stretch
=====================================================================================

- Use Docker for cross-compiling for raspberry pi:

For details on how to install and use docker see: https://confluence.silabs.com/x/Sot4BQ

1. Start the zgw_armhf_debian_stretch_cross docker image with a bash
$ docker run -v<path to zgw source>:/zgw -it zwave/zgw_armhf_debian_stretch_cross bash

2. Build
$ cd /zgw
$ mkdir build_rpi
$ cd build_rpi
$ cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/debian_stretch_armhf.cmake ..
$ make
$ make package

- Use Ubuntu
1.a Install dependenciess
$ apt-get install -y gcc-arm-linux-gnueabihf pkg-config-arm-linux-gnueabihf libtool curl
1.b cross compile openssl-1.0.2
$ curl -L https://www.openssl.org/source/openssl-1.0.2q.tar.gz --output /opt/openssl.tar.gz \
 && cd /opt \
 && tar -xzf openssl.tar.gz \
 && cd openssl-*/ \
 && ./Configure linux-generic32 -DL_ENDIAN --prefix=/usr/arm-linux-gnueabihf/ --cross-compile-prefix=arm-linux-gnueabihf- shared \
 && make SHLIB_MINOR="0.2" \
 && make SHLIB_MINOR="0.2" install \
 && rm -rf /opt/openssl*

1.c libusb
$ curl -L https://github.com/libusb/libusb/releases/download/v1.0.21/libusb-1.0.21.tar.bz2 --output /opt/libusb.tar.bz2 \
 && cd /opt \
 && tar -xjf libusb.tar.bz2 \
 && cd libusb*/ \
 && ./configure --prefix=/usr/arm-linux-gnueabihf/¨--host=arm-linux-gnueabihf --enable-udev=no \
 && make \
 && make install \
 && rm -rf /opt/libusb*

1.d libjson-c NOTE: json-c has a bug, so cross compile doesn't work.
$ curl -L https://github.com/json-c/json-c/archive/json-c-0.12.1-20160607.tar.gz --output /opt/json-c.tar.gz 
 && cd /opt \
 && tar -xvf json-c.tar.gz
