Ubuntu native GDB has terminated prematurely

ChuckInDodgeville:
I'm a long time SE user, but I've never connected the gdb debug features before. Now I am working on a project that runs on Ubuntu 20.4 and I want to use gdb from SE. I followed the outline given in this post:

--- Quote ---https://community.slickedit.com/index.php?topic=185.msg680#msg680
--- End quote ---
The build command correctly uses the cmake generated Makefile, but my attempts to launch the Debug command all end with

--- Code: ---"Error starting debugger: GDB has terminated prematurely".
--- End code ---

I am using the Linux version of SlickEdit Pro 2021 (v26.0.0.6 64-bit Qt4). I'm using g++ 9.3.0. The project uses Qt 5 and hence autogenerates versions of all of the source files after cmake creates the makefile.

The debug command I see in the build window is like this:

--- Code: ---/home/chuck/slickedit-pro2021/bin/vsdebugio -port 8001 -prog "/home/chuck/controller-ui/package/controller-ui/build/controller-ui" --no_hardware --port="/dev/ttyUSB0"
--- End code ---

The file specified by the -prog argument runs when I simply launch it, even in the build window. Launching the program using the default command line gdb also works.

Where else might I look to find out what is wrong?

Dennis:
Try this:

1) From the SlickEdit command line: set-var def_debug_logging 1

2) Debug > Step Into

3) Debug > Stop

4) From the SlickEdit command line: set-var def_debug_logging 0

5) In your configuration directory, under logs, there will be a debug.log, post that here.
The contents of the log file usually reveals why GDB terminated.

ChuckInDodgeville:
Thanks Dennis. Here's the log:

--- End code ---

Dennis:
Looks like /usr/bin/gdb is failing to start.

First thing to verify is if GDB is even installed:

--- Code: ---sudo apt install gcc gdb -y

--- End code ---

If that is copasetic but debugging still does not work, the next step would be to try the GDB which comes pre-built with SlickEdit.

Debug > Debugger Options... > Configurations

Select "SlickEdit GDB" from the list and check [x] Default native debugging configuration.

If that still does not do the trick, the next step would be to check if you can use the command line GDB debugger (/usr/bin/gdb) from a Terminal (outside of SlickEdit), then also see if <slickedit>/bin/gdb will run from a Terminal (outside of SlickEdit).

ChuckInDodgeville:
Thank you. Indeed, I've tried all of these.
gdb is installed.
I can run the program using /usr/bin/gdb from the build window or from a shell outside of SE. Commanding "start" goes where I expect in the program.
I tried using the SE version of gdb. It has the same result. Here's the log.
