# Building from source
In order to build OWPROV, you will need to install its dependencies, which includes the following:
- cmake
- boost
- POCO 1.10.1 or later
- a C++17 compiler
- openssl
- libpq-dev (PortgreSQL development libraries)
- mysql-client (MySQL client)
- librdkafka
- cppkafka

The build is done in 2 parts. The first part is to build a local copy of the framework tailored to your environment. This
framework is called [Poco](https://github.com/pocoproject/poco). The version used in this project has a couple of fixes
from the master copy needed for cmake. Please use the version of this [Poco fix](https://github.com/Telecominfraproject/wlan-cloud-lib-poco). Building
Poco may take several minutes depending on the platform you are building on.

## Ubuntu
These instructions have proven to work on Ubuntu 20.4.
```bash
sudo apt install git cmake g++ libssl-dev libmariadb-dev
sudo apt install libpq-dev libaprutil1-dev apache2-dev libboost-all-dev
sudo apt install librdkafka-dev // default-libmysqlclient-dev
sudo apt install nlohmann-json-dev

## macOS Build
The following instructions have proven to work on macOS Big Sur. You need to install [Homebrew](https://brew.sh/). You must also have installed [XCode for OS X](https://www.freecodecamp.org/news/how-to-download-and-install-xcode/).
```bash
brew install openssl \
	cmake \
	libpq \
	mysql-client \
	apr \
	apr-util \
	boost \
	yaml-cpp \
	postgresql \
	librdkafka \
	nlohmann-json \
	fmt

## Raspberry
The build on a rPI takes a while. You can shorten that build time and requirements by disabling all the larger database
support. You can build with only SQLite support by not installing the packages for PostgreSQL, and MySQL by
adding -DSMALL_BUILD=1 on the cmake build line.

```bash
sudo apt install git cmake g++ libssl-dev libaprutil1-dev apache2-dev libboost-all-dev libyaml-cpp-dev

cd ~
git clone https://github.com/stephb9959/poco
cd poco
mkdir cmake-build
cd cmake-build
cmake ..
cmake --build . --config Release
sudo cmake --build . --target install

cd ~
git clone https://github.com/Telecominfraproject/wlan-cloud-owprov
cd wlan-cloud-owprov
mkdir cmake-build
cd cmake-build
cmake -DSMALL_BUILD=1 ..
make
```
