obdsim on ubuntu 22.04

https://stackoverflow.com/a/26878598

I had the same problem on Linux and I resolved it by installing some libraries and recompiling OBDSim.

I will put here the whole process to make a guide for new users like me.

1. Download OBDSim:

   wget http://icculus.org/obdgpslogger/downloads/obdgpslogger-0.16.tar.gz 

   Or get the most recent version from: http://icculus.org/obdgpslogger/

2. Install OBDSim:

   tar -zxvf obdgpslogger-0.16.tar.gz
   cd obdgpslogger-0.16
   mkdir build
   cd build

   I have to install only these libraries, but in your case keep attention to warning messages of cmake and install all that it ask you to install:

   sudo apt-get install libbluetooth-dev libfltk1.1-dev libfltk1.1 fltk1.1-doc fluid fftw3-dev libgps-dev libftdi-dev
   cmake .. 
   make obdsim
   cd ../bin/

3. Run OBDSim:

   ./obdsim -b -g gui_fltk

   Now you have OBDSim running, but you need a channel to communicate it with your app. You need a serial port working as a bluetooth interface.

4. Creating the serial->bluetooth interface:

   sudo rfcomm bind 0 00:00:00:00:00:00 1 # Change this MAC address, putting the MAC of your device
   sudo sdptool add SP

   You can discover the MAC address of your device by using hcitool:

   hcitool scan 

   It only works when the bluetooth configuration "Visible to all nearby Bluetooth devices" is on your device.
