I'm using GPS version 6.2.2 (20160527) with GNAT Pro 7.4.2 (20160527-49). The debugger that ships with this version of GNAT is 7.10 for GNAT Pro 7.4.2 [rev=gdb-7.10-ref-125-g3d2bab0].
Using GPS, the way to launch the debug session is to go to Debug->Initialize. When I do this, a debugger console pops up down below. Typing show version into the console returns the OS debugger for Red Hat Enterprise Linux (RHEL6) which shipped with the OS, as opposed to the correct version supplied with GNAT.
However, typing which gdb at the command line (outside of GPS) returns the correct version of the debugger installed with GNAT.
How do I get GPS to launch the correct debugger? Where is it getting the OS debugger from?

My Os is : MacOS High Sierra 10.13.5
NetBeans Version : 8.2
Gdb Version: 8.0.1
I can use NetBeans build and run NetBeans Sample C++ Application successfully
but when I try to Use NetBeans to Debug NetBeans Sample C++ Application Quote with gdb, I always get an Error like below, and it always run into the osstream file, I am confused!
I set BreakPoint at main function like below
I don't change any configuration, It is NetBeans Default Configuration for sample C++ project Quote.
Anyone Can help me, how can I fix this error?
I am writing a small Linux app using Visual Studio 2015. To do so, I am using the Visual Studio 2015 Linux Extension, v 1.0.7 (the latest version as I'm writing this post).
I can compile and run the app on the remote environment using gdbserver, but I can't use breakpoints. I don't get why.
Details:
The target environment is a remote Ubuntu 64, on which g++, gdb and gdbserver have been upgraded today.
The extension works in that sense the C++ code is properly sent to the remote environment and properly compiled as a result of pressing F7:
My code (I am using some toy code for this post)
The resulting build log
The code is also properly executed remotely using gdbserver when I'm running it: the output is properly sent back by gdbserver as I can view it in VS's Linux Console Window.
My problem: when I set a breakpoint in my code (as in line 7 of my code above), it is just ignored. And when I just press F11 to start debugging straight at startup, the program just runs as if I wasn't debugging.
I'm wondering whether this is tied to the debugging from host 127.0.0.1 message above.
Of course I'm in debug mode when trying:
Optimizations are disabled:
Symbols are there:
And debug settings are by default. I left them unchanged after having installed the extension. There are no ports set, could it be the cause?
And finally, I can do some step-by step debugging if I replace gdbserver by gdb in my debug configuration above, and if I use F10 (or any other stepping option), not F5, to start debugging. The drawbacks being that I lose the Linux Console and I still can't set breakpoints, they are ignored. I have to step during the whole execution path:
This is the first time I am trying this Linux Extension with a remote environement. I was formerly using it with a local Cygwin and had no issues with breakpoints. But this was the previous version (1.05) of the Visual Studio 2015 Linux Extension so this does not prove anything.
Any idea?
I have an ncurses program that I'd like to interactively debug using CLion. The problem is that when I run the program in CLion to debug it, the inbuilt console where the program is run doesn't display the output of the ncurses program properly.
I'd like to have the program run in my systems terminal so I can see the output properly whilst debugging the program with CLions debugger.
Is there any way to do this?
The best way to accomplish this is to use GDB now it can be really frustrating to get started so Ill show you how I accomplished it in linux
open a terminal and go to your project debug file and type gdbserver localhost:1234 ./myFile
open clion to myFile project and in the upper right corner you should see a build all (or your projects name) click it and go to "edit configurations"
in the upper left corner you should see a plus sign, click it and press "GDB remote debug"
then in "target remote" type tcp:127.0.0.1:1234
Next in "path mappings" press the plus and type /location/to/file/myFile (same file as in 1.) in both Remote and Location
Press OK and in the upper right corner select the name of the configuration that you just made and press debug
you might need to try to restart the gdbserver one more time for this to work but if you did all the steps above you should see a debug prompt come up and on the terminal you should see your project running.
There are some limitations with this for example you always have to run gdbserver localhost:1234 ./myFile command on your terminal for it to work.

I hope this helped :)
In other debuggers, you would do this by running the ncurses application in a terminal, and attaching the debugger to the process using ncurses.
Doing that avoids interference between ncurses (which changes the terminal I/O modes) and the debugger's command-line.
The attach feature is a recently released feature of the CLions debugger:

Debugging ncurses application with gdb
Using GNU's GDB Debugger:
Debugging Ncurses Programs
I've got a problem with gdb debugger. My console app shows me incorrect action results (some trash instead of normal string which I've got from XML ater the parsing) if I run it under a debugger plus I get SIGINT ( I don't output eol character and don't hit ctrl+c). Running my app with no attached debugger (just double click on .exe or Run menu from IDE) shows me correct results. What is the problem?
Some Info:
Windows 7 Pro Sp1 x86
gdb 7.3.1 (MinGW) and gcc 4.6.2 (MinGW)
Eclipse 3.7.1
Here is a gdb trace.
At this screenshot you can see the settings
Probably you have some memory corruption in your application and and they become visible when you use the debugger. In order to solve the problem we need to take a look on your source code.
I'm using Eclipse 3.4.1 with Hp/UX plugin for remote debugging of C/C++. It works very fine, except for one issue: whenever I compile my projects, the output display is Eclipse's console view, but when I run or debug any projects, the output window is the old and not-so-good MS-DOS command window. I haven't find any way to change this behavior.
How do I set the execution output display to Eclipse console?
Update:
Environment: running Eclipse 3.4.1 on Windows XP and debugging C/C++ applications on an HP/UX server.
CDT version is 5.0.0.
Which version of CDT are you using? Because from this "hello world" guide it seems the spawner.dll pretty much handles this console redirection for you.
