Okay I am new to Embedded Linux development.
Right now, I am trying to setup the development environment as efficiently as possible.
I have a python code running on a lightweight Linux based device, that is located remotely
So far I was able to setup my VS Code on my Windows system, in such a way that I can edit the files directly on the remote Linux device.
I followed the instructions below
https://code.visualstudio.com/docs/remote/ssh
https://code.visualstudio.com/docs/remote/ssh-tutorial
Now that I am able to edit my files directly, I face only one obstacle.
I find it hard to traverse to a function/method definition.
In my windows system, I could just Ctrl+LeftClick on a method/function, and it would take me there.
But here when I opened VS Code with the terminal running remotely, I have to do a Ctrl+F and search in the VS Code editor, which is like working on a notepad.
Does anyone know how to get around this?
On my main windows system, I am able to jump to method definitions quickly by Ctrl+LefClick-ing them.
Hope the question is clear enough.
Install the Python extension on the remote server and select the Python interpreter on the Linux device in VS code:
Press Ctrl+Shift+P to bring up the command palette and run the command Python: Select Interpreter.

I have a project kept in Git repository which is compiled on a huge Linux server. Currently, I connect using SSH to the Linux server, modify the files there and then run commands to compile and execute it.
Everything is done in command line which is really painfull and I would like to use an IDE on my Windows machine which can connect to the remote Linux machine using SSH. I just need the IDE for file modification, auto complete and similar stuff, function resolution etc. I don't need to be able to compile or debug through IDE.
Mounting using Samba or Sshfs is out of the question because it is too slow. I need speed. If I click save, it needs to be save. Autocomplete should work like locally, it should work as though the files are on my machine most of the time.
Can somebody recommend an IDE which this qualities and information on how to set it up.
Thanks
The best thing that worked out for me is Unison. You have to have two copies of Unison, one on Windows client and one on remote Linux. You checkout the repository on the remote and then run Unison to synchronize the remote copy to your local. It connects to remote through ssh. Every time file is changed both locally or remotely, the other side gets updated instantly. Works well on slow connections.
You can then use your favorite IDE and work locally. The only quirt is that Unison must be same version and compiled with same Ocaml version (in my case Unison 2.48.4 with OCaml 4.0.4.). I had to compile it manually for Linux and for Windows I downloaded provided binary.
I'm using Visual Studio 2017 to develop a C++ app on a remote Linux machine. First, I run my code on the remote machine and then attach to the remote process using SSH. I attach to Native (GDB) code and hit my breakpoint. The problem is that I can't view the contents of a string received in the debugger.
std::string msg_str(static_cast<char*>(incoming.data()), incoming.size());
The string above is retrieved via ZeroMQ message. If I do a QuickWatch on msg_str, none of the values are in a human readable form.
What I expect to see is:
{"message":"mark","color":"#FFAABB","session_id":"XVg32B","x":34,"y":563}
What do I need to do in order to view this in the VS2017 debugger?

No I'm not compiling with VS. I'm developing a game using the Urho3D engine. On the Linux box I use cmake to create the makefile and then compile/link using make from a SSH bash shell. In VS I get all kinds of build errors.
I've been searching high and low for more information on how to set this project up, to no avail. My biggest problem is that I'm a C# developer trying to come up to speed with C++. The learning curve is pretty steep...
I think the problem is that you've attached to the remote process and VS doesn't know that it's supposed to be looking at a std::string. Are you able to run your test by building then executing from within VS? Does VS know that the source it can see is what's running in the debugger?
It looks like at least some of the string is visible in QuickWatch as _M_p. The result you expect doesn't appear to be a simple string, could this have a bearing?
I just tried inspecting std::string ss ("12345", 5) in QuickWatch in VS2017 (15.7.3) and the string is displayed exactly as you would expect. But I did compile and run (F5) from VS.

You can create a makefile project in VCLinux very easily. Add a new project to your solution and choose Visual C++ - Cross Platform - Linux - Makefile Project. Then copy your sources and makefile into the newly created project directory and add them to the VS project. In the project settings, set the Remote Build commands, e.g. cd $(RemoteProjectDir);make debug and under Debugging set the remote command you want executed.
Depending on how complex your project is, it might be worth creating a very simple, stand-alone test to try out remote building and debugging to verify that you can set a breakpoint and correctly visualise a string.
Not the perfect solution, but I do msg_str.c_str() in the immediate window. Probably wouldn't work well for anything beyond the 7bit ascii subset of utf.
Need help.Wanted to know is there any module in Python which helps to connect to Remote windows and copies some text file, say vb file, and executes it and get the result test file back to source system which may be Unix (mostly) or windows. However, the destination is always remote windows desktop.
Earlier we used Winrm module and ran scripts on remote desktop. However, we got to know that some system does not have Winrm so need to change the tactic, tried searching but could not get any in Python.
You could use module os
and the os.popen() to use NET.exe service command or more advanced scripting tools like https://www.codeproject.com/Articles/9029/Push-and-Run-NET-Code-on-Remote-Machine. At least on windows NT like systems.
Remote development on Linux from Windows is easily doable via SSH.
However, what about the other way? I need to build and debug my Visual C++ application on Windows, but I want to work on a Linux system.
Cross-compiling via MinGW doesn't work because of MSVC-specific libraries
Ubuntu on Windows is a good start, but I'd like to work on a real Linux system
RDP/VNC or something like that doesn't help either, because than I'd work on Windows again
So does a virtual machine
Maybe something like Powershell on Linux + SSH to the Windows Powershell?
I regularly develop Visual C# applications remotely from Linux, not MSVC for the most part, but, like you, I wanted to find a way to build and debug Windows-targeted applications and libraries on remote Windows machines without working directly in the box using RDP, Visual Studio, etc.
It's difficult to answer this question without more information about the development and debugging tools you prefer to use on Linux for the types of applications you develop. I'll try to provide a general overview and update the answer for details you add about your workflow.
Cygwin, similar to MinGW's MSYS, provides a Unix-like environment for Windows. Most importantly, Cygwin, unlike MinGW/MSYS, includes an implementation of the OpenSSH server that enables us to connect to the Windows box over SSH from Linux (or any other device with an SSH client, really). We can install the sshd package using Cygwin's setup utility. After connecting, Cygwin drops us into a Bash shell by default. With this capability, we can:
Execute remote commands and scripts over SSH.
Edit files using our favorite *nix command-line text editor (Vim, Emacs, etc.)
Mount remote filesystems locally using SSHFS (if Windows shares are unavailable).
Forward or tunnel ports if needed.
The availability of a general-purpose shell makes almost anything possible. We can execute batch files, PowerShell scripts, and native Windows executables from Cygwin's shell environment in addition to Linux scripts and Cygwin programs.
For example, we could run msbuild from the SSH session command line to build our VC++ application or we could configure our local GUI editor or IDE running in Linux to execute msbuild over SSH when we click the "build" button.
We could set up a similar environment in recent versions of Windows using the Windows Subsystem for Linux ("WSL", Bash on Windows). I personally prefer Cygwin for greater portability and ease of configuration. Cygwin's sshd can run as a Windows service, and, as an established project, Cygwin integrates very well with Windows systems (user accounts, filesystems, Windows APIs, etc.).
Working with Code
We can choose from several workflows depending on our tools and comfort-level with the command-line:
Completely text-based—all work performed through the SSH session
Use local tools on files mounted in a remote filesystem
Use local tools and synchronize files
I use the first approach. I'm a heavy Vim user, so I connect to Windows machines over SSH to do my work on the command-line using the tools and environment provided by Cygwin. The availability of tools typically found on Linux simplifies many tasks that are hard to do from the default Windows console. We can write shell scripts to automate tasks that Visual Studio might normally do for us. For example, I wrote a wrapper script around mstest that reads the XML test results and outputs them in a format that's easy to read in a terminal.
If we prefer to use a GUI editor or IDE, we can mount the remote code locally so tools can read and write files as if they were part of the Linux machine's local filesystem. We likely still need to use SSH to execute commands needed to build the projects, but many editors allow us to configure this command as the project's "build" action.
Sometimes a remote filesystem is too slow for effective editing. In these cases, we can synchronize files between the Linux development machine and the Windows host using a tool like rsync or the editor's "upload on save" feature (over SFTP, for example), if available.
Debugging
Everything works pretty well until we try to find a way to debug our applications. As of now, there is no reasonable substitute for Visual Studio's debugger when working with Visual C++ projects. We can debug managed C# applications running on the CLR using MDbg, but no comparable tool exists for C++ programs.
We can try to use gdb (from MinGW, Cygwin, etc.) for basic, low-level debugging of native binaries, like reading memory addresses, but the debugger does not yet support reading Microsoft's debugging symbols, so the debugging experience is very limited. Microsoft began documenting the PDB format a couple years ago, so we may see some compatibility in the future. Even so, it will take a long time to produce a satisfactory alternative to Visual Studio's excellent debugging tools.
For debugging, RDP is currently our best—and probably, only—option. For a more native-feeling experience, we can run Visual Studio using rdesktop (or other RDP client) and seamlessrdp to create a single-window RDP session of the Visual Studio IDE instead of a full desktop which integrates with whatever window manager we're using on Linux.
Sometimes we can get around launching a full Visual Studio debugging session for simple debugging scenarios by adding tracing to our application that outputs values to the console or to a log file. In many cases, this is faster than starting the debugger anyway.
We can also try to use Eclipse's CDT debugger configured for the Visual C++ toolchain. This may enable us to perform remote debugging using an Eclipse instance on the Linux machine. I have never tried this approach, and I expect there may be some issues when the application is linked against Microsoft's libraries.
I don't know all your requirements, but maybe you could use a gdbserver on Windows (from MinGW) and remote debug from VSCode on Linux - or any other environment you like. You can find more details in this post here. (Watch out, VSCode prevents you from running gdb unless it’s signed as mentioned in the first link.)
There is also a Native Debug VSCode extension that could be helpful.
Another solution I can think of is to use Visual Studio Online (free for small teams up to 5 persons) as build server.
As you have said, the other way around is pretty easy and nowadays even officially supported by Visual Studio 2017.
Most probably, the VS remote debugging tools for Windows wont be helpful for you.
I'm usually using VM/linux to run scripts, copying script using putty
or writing them directly there, but some times too many opened windows is not that comfortable..
I was recently trying to run shell script, using RUN option in Notepad++
to use build in Ubuntu in win10 anniversary, but can't really manage to get the right syntax to do it.. and didn't find any plugin to do so..
I would appreciate if anyone can put me to the right path in this one.
I found that it is also possible to do it using sygwin, by C:\cygwin\bin\bash --login -c "command.sh" but again its an extra software piece... and bit far from natural Linux environment, and slight different paths etc..
there is also a solutions to run some shell IDE using X11 using Xming, to work with Linux VM without switching between the opened windows. but in this case Question is the where can I find a proper shell IDE for linux, capable to run shell scripts directly from it, without living the IDE window, like all other IDE's do ?
any real solution would be appreciated.
It will NOT replace a pure Linux environment but, it is a closest I've seen
