GNAT serial comm under FreeBSD - PROGRAM_ERROR raised

GNAT serial comm under FreeBSD - PROGRAM_ERROR raised

[darek]

Hi All,
  I have installed the AUX compiler from http://www.freshports.org/lang/gcc-aux/ (gcc version 4.9.2, 20141030)  on my FreeBSD (ver. 9.2, amd 64)  machine. The PC needs to talk to an external device via the serial port. The program compiles without any problems but at  the run-time, I got the following exception:

 raised PROGRAM_ERROR : Serial Communications not implemented

If this is a feature (due to any imaginable issues), is there any other package that  handles the serial communication under FreeBSD?

BTW, the status of the port on http://www.dragonlace.net/ is described as a "perfect". 


Cheers,
  Darek 


Test program:

with Ada.Text_IO; use Ada.Text_IO;
with GNAT.Serial_Communications; 

procedure TestSerial is

   package Serial_IO renames GNAT.Serial_Communications;
   
   Port_ID : Serial_IO.Serial_Port;
   Port_Name : Serial_IO.Port_Name(1..10) := "/dev/ttyu0";

begin
   
   Put_Line("Test  serial port");
   Serial_IO.Open(Port_ID,  Port_Name);   

   Serial_IO.Close(Port_ID);
   
end TestSerial;

I think this may just be the current state of the
"GNAT.Serial_Communications" package for FreeBSD.

You could look into how the package is implemented for other Unix
platforms (e.g. Linux), and see if that can easily be ported to FreeBSD.
I wouldn't expect it to be too hard.

GCC 4.9.1 and 5.0 have implementations for Linux and mingw.

Hi All, 
As a work around I use the 32bit gcc/GNAT compiler on Linux and copy  the executable to the FreeBSD machine. It works well due to the FreeBSD-Linux compatibility layer.
