Billboard

Digital billboard for WnCC's InstiApp in SFML

Dependencies

The package depends on SFML (2.5+), CURL (with OpenSSL binaries required for HTTPS requests) and nlohmann::json.

Setup

First, create hexdumps for all assets by running make_xxd.sh in a Unix like environment. You need to do this every time you change anything in the assets folder.

To compile, install SFML and CURL developmental files by running (for a distribution supporting apt) sudo apt install libcurl4-openssl-dev libsfml-dev and run make to compile. You also need to download include files for nlohmann/json and put them in the include folder.

Windows

You need mingw-w64 with POSIX thread support to compile under Windows. To compile, download SFML, CURL and OpenSSL binaries. Keep static binaries in the lib folder, include files in include and run mingw32-make to compile.

Raspberry Pi

First, you need to compile mickelson/sfml-pi, and then compile this repo with those dependencies. This can be done by running such a script:

#!/bin/bash

# Get dependencies
sudo apt-get -y install cmake libflac-dev libogg-dev libvorbis-dev libopenal-dev libjpeg8-dev libfreetype6-dev libudev-dev libraspberrypi-dev libcurl4-openssl-dev

# Clone mickelson/sfml-pi
git clone https://github.com/mickelson/sfml-pi sfmlpi --depth 1
cd sfmlpi
mkdir build
cd build
cmake .. -DSFML_RPI=1 -DEGL_INCLUDE_DIR=/opt/vc/include -DEGL_LIBRARY=/opt/vc/lib/libbrcmEGL.so -DGLES_INCLUDE_DIR=/opt/vc/include -DGLES_LIBRARY=/opt/vc/lib/libbrcmGLESv2.so
sudo make install
sudo ldconfig
cd ../..

# Clone this repo
git clone https://github.com/pulsejet/billboard
cd billboard

# Get include files
wget https://github.com/nlohmann/json/releases/download/v3.4.0/include.zip && unzip -o include.zip && rm include.zip

# Dump assets
./make_xxd.sh

# Produce an optimized build
make CXXFLAGS="-O3 -Wno-psabi"

Configuration

See assets/config.json for the default configuration. You may change one or more values by having the file config.json with relevant keys in your working directory when you run billboard. For documentation, check src/config.hpp.
