A collection of Fortran 2008 interface bindings to the Eclipse Paho MQTT client library, to connect Fortran to the Internet of Things. Currently, fortran-paho is just a proof of concept.
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 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
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
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
