Ok, so we may have 2 issues at and.
the debugger never returns on
set inferior-tty /dev/pts/2
which should have been created by the IDE.
or the IDE never gets the result, because something went wrong with
creating it => but then it should not have gotten as far as sending
the above...
So still the below stacktrace,. shows the IDE waiting for gdb to
return output. yet it should do processMessages, so the ide should
be responsive.
Strange
anyway:
in options, on the debugger tab (where you select /usr/bin/gdb), is
a list of setting (in an object inspector like grid)
One of the settings is
ConsoleTty
it is empty by default.
Put /dev/null in there and see if it helps.
Or if you need to see the debugged apps terminal output, then open a
terminal (xterm, or any other) yourself, type "pty", and it will
give you something like /dev/pts/<n> which you can put into that
setting (so long as you leave that terminal open.
I wonder why that hangs. Nothing there should have changed...
unless some file/handle stuff in fpc changed? getpt() fcntl()
tcsetattr() __write() ....
^C
Program received signal SIGINT, Interrupt.

Argh, no => I overlooked the top 2 frames...
I do NOT like them (I do not know yet why not ..)
try the /dev/null
It should work around
At this point there should not be any data to be read.
So the question is why on your system is read triggered.
Still locks up I'm afraid.
You are right, sorry, there is a bunch of nested {$IFDEF}... (I must
have had a bad day when I put that in)
the pseudo console is still accessed, even if you specify another one =>
I am fixing that now.... (next hour)
Still interested to know if the current trunk (error checking) helps.
