# fortran-paho

A collection of Fortran 2008 interface bindings to the

[Eclipse Paho](https://www.eclipse.org/paho/) MQTT client library, to

connect Fortran to the Internet of Things. Currently, *fortran-paho* is just a

proof of concept.

## Requirements

A Fortran 2008 compiler and the Eclipse Paho C library are required to build and

link the library. On FreeBSD, just install the package `libpaho-mqtt3`:

```

# pkg install net/libpaho-mqtt3

```

Alternatively, clone the [repository](https://github.com/eclipse/paho.mqtt.c)

and build Paho from source:

```

$ git clone https://github.com/eclipse/paho.mqtt.c

$ cd paho.mqtt.c/

$ mkdir build && cd build/

$ cmake ..

$ make

$ make install

```

## Build Instructions

Clone the repository with Git and execute the Makefile:

```

$ git clone https://github.com/interkosmos/fortran-paho

$ cd fortran-paho/

$ make

```

You can override the default compiler (`gfortran`) by passing the `FC`

argument, for example:

```

$ make FC=ifx

```

Link your Fortran programs against `libfortran-paho.a -lpaho-mqtt3c`, for

instance:

```

$ gfortran -o example example.f90 libfortran-paho.a -lpaho-mqtt3c

```

## Examples

The source code of some demo applications is located in directory `examples/`.

The examples require a running MQTT message broker. Either start a local broker

or connect to `iot.eclipse.org` on port `1883`.

* **subscribe** connects to an MQTT message broker, subscribes a topic, and

  prints the payload of received messages.

* **publish** connects to an MQTT message broker and publishes to a topic.

Build the examples with:

```

$ make examples

```
