[Lazarus] TThread in console mode program.

[Donald Ziesig]

Hi All:

I am still trying to get timers to work in a console mode program.  
While I was doing that I ran into problems with TThread.


Question:  Do console mode programs have a "run loop"?.  The reason I am 
asking is that both Raspbian and Linux Mint TThread's Synchronize method 
apparently does nothing (it works fine when used with LCL).  I can call 
it, but it doesn't run the method passed as a parameter, nor does it return.


I wrote a trivial console mode program that uses TThread and tested it 
on both Raspbian and Linux Mint with exactly the same results.

The simplest Execute method fails:


procedure TXThread.Execute;

begin

   Synchronize( Callback );

end;

I have tried stepping into Synchronize, but even the debugger seems to 
get lost.


If I change Execute to:


procedure TXThread.Execute;

begin

   Callback;

end;

the Callback method is invoked (seemingly in the main thread, but I'm 
not sure... Will have to figure it out later).


Thanks,


Don Ziesig
