• Sources https://sourceforge.net/projects/fldigi/files/
• GIT repo https://sourceforge.net/p/fldigi/fldigi/ci/master/tree/
• Packages & Libs needed :
  • libfltk1.3-compat-headers libfltk1.3-dev
  • pkg-config
  • libpng-dev
  • libsamplerate0-dev
  • libsndfile1-dev
  • portaudio19-dev
  • libhamlib++-dev
  • libudev-dev
• Check the FLTK version:

  $ fltk-config --version

• Check if sources/config.h is set to the correct values according to FLTK version values :

      /* FLTK API major version */
      #define FLDIGI_FLTK_API_MAJOR 1
      /* FLTK API minor version */
      #define FLDIGI_FLTK_API_MINOR 3
      /* FLTK API patch */
      #define FLDIGI_FLTK_API_PATCH 4

• ./configure
• make

• Remote weather stations.
• Portable HF setups. Typically, HF digital setups are bulky and require several interconnected pieces of hardware, usually via audio cables. This library, along with some custom hardware, could allow a walkie-talkie sized HF digital radio that's completely integrated.
• Emcomm
• 'Headless' operation on a Raspberry Pi, BeagleBone, or any number of other Linux-based single-board computers.
• Putting a more 'user-friendly' GUI on top of FLdigi.
• Web enabled FLDIGI via HTML5 and some Javascript, that could be accessed from anywhere. Python's Flask / Django along with Bootstrap, and a few REST calls, for example.
• Allow a phone or tablet to send and receive FLDIGI messages via a custom app. There is an Android version of FLDIGI, but that might not be the best approach for every problem. A more custom application could be created to use only a particular mode and send pre-formatted data, for example, with considerably less work than it would be to fork the FLDIGI mobile application and update it.
