Hi Matthew,

thanks for the well targeted questions.

Yes, what Lars describes is what I am also doing, except that he renamed 
my main.c to hello.c

During ./configure I do get a limited number or 'yes' lines including 
both Scope and Debugger. I checked that after running configure and it 
was consistent with args provided.

I confirm that in the plugin manager, I only have scope checked. 
Debugger is not checked.

As I noted, when I use the gear icon ( ie the geany run )  to run the 
prog from geany, I get a VTE terminal window which shows the output msg. 
If I use Debug | Run/Continue I get no output anywhere I can see and the 
only debugging action this is not greyed out is Terminate.

Running from gdb directly showed a message saying I needed to install 
glibc-debuginfo . This was not shown anywhere in scope, again suggesting 
that it is not connecting to gdb at all. Having installed this I can 
step and break the executable and get expected output using  gdb from 
command line.

Returning to restart geany and scope ; re-select the executable and run 
it from the debug menu , I get the same results, all degugging icons are 
grayed-out. The status bar shows "Busy" bottom , right. All I can do is 
'terminate'.


In scope.conf , I see the following but I do not get any VTE when 
running under scope. Only when running directly in geany.
debug_console_vte=true

Nothing showing is system logs, nothing new on terminal from which geany 
is run.

Any idea where to look ?

thanks
