Super simple and helpful... just like it should be. Great job explaining!

This setup tutorial is so simple 😊
=> should hopefully get much more likes (and being pushed on youtube)
Thanks a lot for this very nice introduction !! 😉

Hi bro. Got the problem : "The preLaunchTask 'C/C++: clang build active file' terminated with exit code -1.". Any idea how to solve? Thank you

I installed both extensions like you said but when I click run, the search bar on top asks me to select a debug configuration. It was not as easy as just clicking run and debug. I had .vscode folder auto generate with tasks.json and launch.json where I had to change the command configuration from ""/usr/bin/clang" to ""/usr/bin/clang++" manually. I doubt code runner is doing what needs to be done. Any solutions to this pain point would be greatly appreciated.

When fixing all these issues and running, my "Hello world" comes in the debug console and not in the output console. VERY WEIRD and I am sure I have messed my VS code enough in the past years to encounter this problem.

Please, make a guide, how to use custom libraries, I can't find out, how to do it on macOS((

which c++ standard is applied to your g++ or clang by default? Mine is 199711 which is ancient. And I know I can pass in the flag to set it to a modern one with -std=c++20, but I wonder if I did anything wrong.

so simple and well explained!! Thanks for share

Guys, how to fix "Errors exist after running preLaunchTask 'C/C++: clang ?

[torpidfella]

The preLaunchTask ‘C/C++: clang build active file’ terminated with exit code -1.

Hello
I've tried doing this but instead of showing my output "Hello World" I got "Activating task providers cppbuild" instead. Why?

[Imparavitor]

It display 150 hours for standby time, after i wrote xcode-select --install. Is it normal???

Anyone have clarification on the .run extension for me please?

I ask because I've been working on vscode for about a week now after starting a course to expand my c++ skills. The issue I've had is with the running of the code. I installed the c/c++ extension and that was it. The instruction didn't say anything else and I kept getting an error regarding the a.out file which I assume is the compiled executable or something like that.

I was on stack overflow when someone rudely told me to read the vs code manual and that I needed to set up prelaunch tasks. I was watching videos on prelaunch task setup when I realized that they all have different steps, missing steps, different versions, different OS etc.. I could never get the desired outcome.

Now, I come across this video and the only thing that's different is that I installed the .run extension. Runs code fine. However, the description says it runs "CODE SNIPPET". To me this sounds like its for small code files... maybe its just the chosen description, but I wonder if this completely takes care of the prelaunch requirements (with respect to JSON file) or do I still need to have that set up.

If I do need to set up the JSON configuration still, could someone please point me to an in-depth walkthrough to do this? I have a late 2017 MacBook Pro. Everything I've found implies I have strong working knowledge of VS, though I typically use basic editors when learning and have never used a program as complex as this for the task.

Sorry for the long post, and thanks in advance for any helpful comments or direction regarding this matter.
