On Linux, the development of A/C + + program, perhaps you will be directly (local or remote) login to Linux, open the editor after writing the code, the use of gcc/g++ to compile, encountered to debug the wrong time, you will choose to use GDB for debugging. Now, if you happen to like Visual Studio, you don't have to change your habits, write programs in Visual Studio, send them to Linux remotely, and even connect gdb to debug. This can take advantage of the powerful IDE capabilities of Visual Studio to develop programs such as embedded systems or IoT devices.

Figure: There should be a lot of developers who write programs on Linux to work like this, right?

How to do?

First of all, you must use Visual Studio 2015, you can use the free version [1] of Visual Studio Community or other higher-level version, remember to check the installation of Visual C + + and C + + cross-platform action development of these two components :

Then just install Visual Studio GDB Debugger This expansion suite and you'll be able to choose the project template for Makefile Project (GDB) in Visual Studio's Visual C + + > cross-platform Project type.

After setting up the project, the start screen will have a simple explanation of how to connect to the far end of GDB to do the debugging, there should be no big problem. SSH-related tools can be used to download related tools to the PuTTY website.

First in the project right-click on the selection of content, set the debugging environment, such as the remote host address, and then authentication with the Pub/private key, as well as the way to connect (SSH or plink), and so on, it is important to note that the connection server is the use of RSA public private key way to authenticate, So you have to generate a set of RSA keys, and then put the public key on the Linux host, and then set it to authenticate with the private key (the. ppk file in the diagram).

Then it is set how to upload the program to the target Linux machine on the compiler, then use the gcc/g++ on the machine to compile, switch to the NMake Settings page, set the build command:

Here I set the value is:

D:\tools\pscp.exe-i $ (privatekey) "D:\Temp\Project1\Project1\main.cpp" $ (remoteusername) @$ (remotehostname): $ ( Remoteworkingdirectory)/main.cpp

$ (secureshellexecutable) $ (remoteusername) @$ (remotehostname)-I $ (privatekey) "CD $ (remoteworkingdirectory); g++-G Main.cpp-o $ (remoteexecutable) "

Here I use PSCP file on the Linux host, and then use g++ to compile, the other variables are the values set above, you can according to your tool and file location to make changes.

You can then start writing the program, and then set the breakpoint as if you were writing other programs in Visual Studio, but you can start the remote debugging by selecting remote GDB at execution time.

It looks like it's all in Visual Studio, but this code has actually been sent to the Linux host for compilation and debugging using GdB!
