Debugging on OSX: how to set tty
« on: April 23, 2018, 12:12:11 am »
Hi all,

I managed to build the latest svn of Code::Blocks and of the FortranProject plugin.
It is working! I am debugging a fortran project using the Intel debugger gdb-ia
coming with the Intel Fortran Compiler.
While debugging, in order to have to program output on an iTerm window I did the following:

in Environment settings -> General settings
I set "Terminal to launch console programs:" as
Code: [Select]
osascript -e 'tell app "iTerm"' -e 'create window with default profile' -e 'tell current session of window 1 to write text "$SCRIPT"' -e 'end tell'
and in Settings -> Debugger
I set "Arguments":
Code: [Select]
--tty=/dev/ttys000
But this only works if the iTerm window that is opened actually is /dev/ttys000.
How can I set the ttys number of the gdb --tty option to match that of the window that will be opened?

Thanks for any help,

w

PS: why does the debugger take approx 1 min to start on OSX while it takes less than 1 sec on Linux?

There is a code that tries to detect tty and it then executes the correct gdb command to set the redirection. I guess this code doesn't work correctly on macOS.
Search for console in the code. Probably in cbplugin.cpp or somewhere in debuggergdb/*.cpp.

Is this the same if you start it from the command line?

Er... yes, the code is there in cbplugin.cpp
I have no clue on why it does not work

It seems that running the debugger from the command line there is no delay whatsoever.

Have you tried to pass the same options cb is passing?
