No symbol table loaded - GNAT Community 2019

["Ricardo Brandão" <rbrandao.br@gmail.com>]

Hi,

I'm starting in Ada. The first thing I did was install GNAT Community 2019 on my computer with Windows 10:

See below a copy of about box:

GPS 19.1 (20190106) hosted on x86_64-pc-mingw32
GNAT Community 2019 (20190517-83)

the GNAT Programming Studio

(c) 2001-2019 AdaCore

So, I was following the tutorial of Ada Core site, and at Debug section [1] I didn't get see the debug working.

The steps (following the tutorial):
1. Clicked on Build & Debug sdc.adb toolbar button.
2. On the call stack window, clicked on the menu (three lines on the top right corner) and mark Show Frame Number.
3. Clicked on the Debug continue button and type input.txt in the text input field. 
4. Here I found the first thing different: the tutorial ask to check ‘Stop at beginning of main subprogram’ and uncheck ‘Use exec dir instead of current dir’. Only ‘Use exec dir instead of current dir’ could be found.
5. But I clicked Ok to continue.

And the problem: when clicked ok, I got the message:

file D:/GNAT/2019/share/examples/gps/tutorial/obj/sdc.exe
(gdb) catch exception
(gdb) start input.txt
(gdb) No symbol table loaded.  Use the "file" command.


Looking the output on Messages tab, I could see the gprbuild output:

gprbuild -d -PD:\GNAT\2019\share\examples\gps\tutorial\sdc.gpr -XBuild=DEBUG

Is there any problem with GNAT installation? 

Thanks
