Launching stuck at start
Submitted by Ainars Zvaigznitis on Mon, 2022-05-23 08:38
Eclipse 2022-03 (4.23.0) for windows - looks like the same problem as described below in 'Stuck in "Starting program"'. Launching (gdb at Linux) just stuck at "Starting program" - in my case at 20%, the same error message and nothing in console at all.

Hi Ainaros,
I haven' tested 4.23.0. The last one I tested was 4.19..0. If you still have the problem, would you please try the plugin on 4.19.0
debugging frozen
Submitted by Jamie Mising name on Wed, 2022-04-13 08:21
I am running "Eclipse IDE for C/C++ Developers (includes Incubating components) Version: 2022-03 (4.23.0) Build id: 20220310-1457" locally on a Mac,
and debugging c & C++ executables running in a Linux machine, running "GNU gdb (GDB) Red Hat Enterprise Linux 7.6.1-120.el7".
I installed "Direct Remote C++ Debugging 1.2.0.0" on my Eclipse and finished the setup.
The very begining of the debug worked well, But then after a while, the 'Variable's view showed errors on some variables, then all variables are empty now.
Even worse, now it is stuck in a step, none of 'Step Over', 'Step Into' or 'Resume' could move a step!
I could not even terminate the debugging. Seems Eclipse doesn't recognize any instruction from me.
What could I do? Any help is appreciated!

Hi Jamie,
I haven't tried the plugin on 4.23. I tested it on 4.19. If you still have the problem, Do you mind testing it o 4.19?

Stuck in "Starting program"
Submitted by Shadi I on Tue, 2020-04-07 08:26
launching the debug configuration gets stuck at "starting program" (45%).
It gets stuck like this forever. Then if I try to abort I get the error: "Could not start gdb on the remote host by ssh. See console output for more details"
note: the console has no output at all. Even when I redirect to a local file.

Problem starting debug session
Submitted by Tony M on Wed, 2019-02-13 15:02
Hello, I am trying to debug a program on a remote Linux server from my Windows laptop using your plugin. I set up a remote debug configuration, but when I try to start debugging, it asks me for SSH credentials, and then gives me this error: Error creating Terminal Do you have any idea what it means and where to get more information? I am not sure if I specified all the parameters for my debug configuration correctly - is there a tutorial on how to use your plugin? Any help would be greatly appreciated -- thank you!
Re: Problem starting debug session
Submitted by Mohamed Abdelazim on Tue, 2019-07-30 15:14
Which Eclipse versoin you are using?
Away from the pluing, try to create a terminal for this connection inside Eclipse and see if it works.
No, there is no tutorial for the plugin. The plugin is quit simple, the steps in the "Details" section here should be enough.
Problem with Setting remote system type in release 1.2.0.0
Submitted by ALAN O'KEEFE on Sat, 2018-08-18 23:19
I have installed version 1.2.0.0 in Eclipse Neon.
When I try and create a new Connection after selecting "Direct Remote Debugging Launcher", it pops up a dialogue box to "Select remote system type", but the list is empty? Am I supposed to setup the system types somewhere else in eclipse?

You need to setup "Remote System Explorer" plugin.
You can do that from "Hep" -> "Install New Software....."

I have just fixed the problem by adding "Remote System Explore" dependency in the plugin.

SSH Ports
Submitted by Jack Heaff on Thu, 2018-06-21 08:45
Hi,
I am running Eclipse Neon on Linux and my target is a centos virtual box. I am using vagrant to contact the virtual box.
What SSH ports or GDBServer ports does your plugin use? I will have to set up port forwarding in my vagrant config file to allow this to work.
Thanks!

Re: SSH Ports
Submitted by Jack Heaff on Fri, 2018-06-22 08:28
So I now have the remote debugging plugin working perfectly! It seems that if any of the "prerun commands" in the debug configuration contained commands that printed to stdout, like "pushd or popd", then the plugin seemed to fail. By piping stdout to >/dev/null it now works!
Unable to run gdb

Could not start gdb on the remote host by ssh
Submitted by Gael Alassoeur on Wed, 2018-02-07 07:51
Hi,
I think that I missed something in the configuration.
I have a Linux dev server with Eclipse and a solaris 10 Sparc target.
Workspace/ eclipse project and sources are shared via NFS
When I launch debugging, the process get stalled on "Starting Program".
On the server side, I see a new sshd process launched.
When I stop, I got the error "Could not start gdb on the remote host by ssh. See console output for more details"
In the debugger tab, the GDB debugger refers to one defined on the Solaris server.
Is there someone who had this pb ?
Thank you very much
Regards
Gael

What do you mean by "When I stop, I got error" did you stop for debugging for you stopped the sshd process ont eh server?
Your setup sounds correct.
Is the sshd process still running after it said "Could not start gdb on rmeote host"

Hi, I have a completely different issue:
I am running windows 10 on my local (laptop) with Eclipse mars (4.5.2), where as my server runs linux with gdb 7.5.1

I got some idea what is happening now. Each time the plugin hit the debug it try to connect to a dev/pts for input/output. But the plugin didn't get the one belong to my account (there are different users using the debug server aswell), therefore, it return a "permission denied" error. I have observed, each time the plugin try increment 1 on the /dev/pts, e.g. /dev/pts/14, /dev/pts/15, /dev/pts/16, etc.

Does a normal ssh program likes putty works fine with same account ? If yes, I guess the problem in the ssh options which the plugin used. One suggestion is build a separate program which does only ssh connect with same as the plug-in and try to figure out where is the problem.

pids of the server process in gdb 7.2 and loading core files
Submitted by Asif Khan R on Tue, 2015-12-22 06:17
Just what i had been searching for more than a year. The existing remote debugging with gdb-server and gdb was not very easy to use, as we already had to do lot of cross compilations on linux and configurations on windows eclipse.
I used this and tried to attach a debugged to a running process of linux, it listed all my windows processes, i figured that it was because my version of gdb does not support listing the threads and process, so i had to write a hack to change the "listtasks.exe" to actually do a connect to the linux machine and get all the processes. Thought i will check with you and see if we can have an easy way.
Additionally, i have been trying to load a core file using the windows gdb to load a core. This means that i need to have a target gdb on my machine and it was not easy. Can we adapt this project to also work for loading core file. I would actually like to contribute. You could probably guide me how to start contributing and let me know ur email id.

Gdb version 7.10 problem
Submitted by Mohamed Abdelazim on Mon, 2015-11-02 06:41
HI
Thanks for the information.
It sounds the plugin has problem with version 7.10 now. This version is not tested yet.
Please send me your contact email so we can add a support for it.
As as a temporary workaround you can install gdb version 7.2 on the server and make it the default gdb
Thanks a lot for sharing this with us.

Please make sure the ssh server is running on your server and gdb is installed.
You can check this by connect by ssh to the sever from command line or from putty and run gdb manually .
Please send me the OS you run Eclipse on it, the server OS and the gdb version.
Please also send the whole console output when you run the debugger.

As gdb cannot find
/dev/ttyp2on the remote machine, I create a link to/dev/tty1as a temporary solution:e.g.,

It sounds the gdb in the plugin looks for the /dev/tyyp2 always for some reason. Your workaround sounds good. I will try to figure out why it wants /dev/ttyp2.
