The Run view on the left shows debugging information. This is a breakpoint that the C++ extension automatically sets for you: The editor highlights the first statement in the main method. In the Debug Output tab, you see output that indicates the debugger is up and running.

The Integrated Terminal appears at the bottom of the source code editor. Before you start stepping through the code, let's take a moment to notice several changes in the user interface:

Press F5 or from the main menu choose Run > Start Debugging.

Go back to helloworld.cpp so that it is the active file.

Paste in the following source code: #include #include #include using namespace std int main (), which if helloworld.cpp is the active file will be helloworld.īy default, the C++ extension won't add any breakpoints to your source code and the stopAtEntry value is set to false.Ĭhange the stopAtEntry value to true to cause the debugger to stop on the main method when you start debugging. In the File Explorer title bar, select New File and name the file helloworld.cpp.

c_cpp_properties.json (compiler path and IntelliSense settings).

As you go through the tutorial, you will create three files in a. command opens VS Code in the current working folder, which becomes your 'workspace'. Then create a subfolder called helloworld, navigate into it, and open VS Code in that folder by entering the following commands: mkdir projects cd projects mkdir helloworld cd helloworld code.

Next install the GNU compiler tools and the GDB debugger with this command: sudo apt-get install build-essential gdb Create Hello Worldįrom the terminal window, create an empty folder called projects to store your VS Code projects. An out-of-date Linux distribution can sometimes interfere with attempts to install new packages.

If GCC isn't installed, run the following command from the terminal window to update the Ubuntu package lists. To verify whether it is, open a Terminal window and enter the following command: gcc -v Fortunately, that's easy.įirst, check to see whether GCC is already installed. These tools are not installed by default on Ubuntu, so you have to install them. You can install the C/C++ extension by searching for 'c++' in the Extensions view ( ⇧⌘X (Windows, Linux Ctrl+Shift+X)).Īlthough you'll use VS Code to edit your source code, you'll compile the source code on Linux using the g++ compiler. To successfully complete this tutorial, you must do the following:

If you have trouble, feel free to file an issue for this tutorial in the VS Code documentation repository. For those subjects, there are many good resources available on the Web. This tutorial does not teach you GCC, GDB, Ubuntu or the C++ language. GCC stands for GNU Compiler Collection GDB is the GNU debugger.Īfter configuring VS Code, you will compile and debug a simple C++ program in VS Code. In this tutorial, you will configure Visual Studio Code to use the GCC C++ compiler (g++) and GDB debugger on Linux. Configure IntelliSense for cross-compiling.If you have any queries, feel free to ask in the comment section. That’s how you compile and run a C program in your Linux System. Time to run your first program by running the below command in your terminal to execute your first program. $ sudo gcc firstProgram.c -o firstProgramĪ new executable file with the name firstProgram will be created in the same path you have executed the above code. Make sure you are on the correct path where you have saved your program in your system. In order to build an executable file for your program, enter the below command in your terminal. In this example, I have saved with the name firstProgram.c. printf() displays the string inside quotationĪfter you are done, save your file with a. Now we write a simple basic C program to print LinuxShellTips on screen. $ sudo apt install build-essentialĪfter installation is complete, all required packages will be installed in your system.

To run and compile the C program properly in your Linux system, you need to install build-essential package, which include GCC/g++ compilers and libraries which are required to compile and run C programs in Linux. In this guide, we will be more focused on GCC Compiler, and all of the steps from compiling to running C programming are performed on Ubuntu 20.10, which is Debian-based distribution.
