GDBServer wont start on host machine - gdb

I migrated from my old Linux Mint to the new Ubuntu 18.04. and doing this I am trying a "newer" version of Eclipse. Therefore I installed Eclipse Photon and set up my remote application debugging like I did for Eclipse 3.8., using the Oselas Toolchain and a CortexA8.
The problem I am facing is, that the GDBServer on the host machine won't start automatically. After a successful connection I have to start it on my own:
Is there any new feature that exits the server immediately after starting?

qt 5.15 Failed to connect to server. Check your network connection and try again

I am using Ubuntu 20.04 and I trying to install qt 5.15, however, the online installer always displays the above mentioned message. I have already tried waiting (maybe it was just a problem with the server), rebooting my machine and nothing worked.
I tried in another machine with Ubuntu 22.04 and it worked.
Does anyone has any clue of how I can fix this problem for my 20.04 Ubuntu machine?

CLion: "Remote GDB Server" targeting Windows

Is it possible to run a remote debug session targeting Windows with CLion?
The docs say that I can do any system that has gdbserver:
Remote OS: any supporting gdbserver and SSH
However, when I try to run my remote app, I get an error:
10:53 PM Build finished in 3 sec, 44 ms
10:53 PM Error running 'remote'
1: 'env' is not recognized as an internal or external command,
operable program or batch file.
I can't find a place where I could see the whole command that CLion runs that causes this error.
Here is my configuration:
After some investigation, I have come to the conclusion that it is impossible to remote debug a Windows app with CLion 2021.3.1 (regardless of Host platform).
CLion does not support remote debugging when targeting Windows OS using GDB Server (hence targeting Windows is impossible) due to:
CLion does not handle cases when SSH Server is using a non-Unix shell like CMD.exe or PowerShell. Commands like exec, env, chmod can’t be handled. This can be circumvented by using a Unix shell:
a. Unfortunately, connection fails for MSYS2 Bash and Git Bash when Windows OpenSSH Server is configured to use one as a default shell.
b. Windows WSL SSH Server works. Connection is established, Unix commands are recognized. WSL must be installed. It is not easy to configure WSL when Windows itself is running on virtual machine.
c. MinGW64 SSH Server. Didn’t test it.
Uploading binaries via SFTP fails when OpenSSH Service is used. Can be circumvented with 1.b..
CLion doesn’t consider the binary’s file extension. It always assumes that the binary is built for Linux, hence the attempt to transfer fails, when a binary has an .exe extension (fails to find test, though test.exe was built). This is a major bug that prevents remote debugging targeting Windows. There are, however, ways to work around:
a. Manual renaming before running debug. Unacceptable.
b. Adding a conditional custom CMake command. May work but pollutes the CMakeLists.txt
CLion can’t connect to MinGW GDB Server it has started. Connection times out. However, if the Server was started from a terminal, CLion connects successfully and is able to run debug as intended. This can ONLY be worked around MANUALLY:
a. In Edit Configurations… one must put a stub command in GDB Server:, for example ‘sleep’. In GDB Server args: ‘5’. This will give a time to manually run the gdbserver.exe command via an SSH connection in Terminal.
These issues were reproduced for CLion versions for Windows 10 and Ubuntu 20.04.
3. and 4. are very serious and prevent from remote debugging targeting Windows as it was intended to be done.
This happens when CLion connects to the Server it has started:
This is a work around:
As can be seen from the screenshots, with this approach GDB’s console does not catch the output. You must switch to Terminal to see it.

Indexing in remote c++ eclipse project does not start

Indexing does not start ,without any error. I tried the RDT Remote Fax Indexer without success as well
Thank you

Problems running remote C++ program in Netbeans

Here is the scenario.
I have a C++ application using CMake that has been setup on Ubuntu server machine. I have setup a remote development interface to it using Netbeans 6.9 on client machine, and I have been able to build it.
The problem is that (as per the setup of CMake script) the executables from the program are going to another directory in the server. When I try to run the program, Netbeans asks me for executables which I can't spot out on client machine (as they are residing on server machine).
Is there a way I can get the executables on local machine OR have a way to give their location to my Netbeans application.
Thanks for your help.

Can I build and debug c++ programs on remote machine?

I am on windows XP want to build the programs on linux remote pc
i have eclipse Ganymede, CDT, RSE installed on remote machine... but how to configure all this?
am I doing correct? could anybody suggest
You could access your remote machine using VNC or similar remote desktop infrastructures. That would allow you to work with Eclipse (edit, build, run, debug, etc) as you would in your local machine.
If bandwidth is too narrow or you don't manage the Linux box, you could access via SSH or telnet and work in console mode (with Emacs/Vim, gdb and all that stuff).
Take a look at https://github.com/ericwoodruff/rmake you would configure your IDE and edit code locally but it uses rsync to build on the remote machine. I've used it at HP to build C++ programs across multiple platforms, linux->windows, windows->linux. It works in the command line and I've used an eclipse builder to invoke it as well. If you enable --no-decorate Eclipse can even parse the build output into the problems view.
