Bazel Tutorial for C++ in 30 Minutes

In this video, I will show you how to use Bazel to build your C++ programs.
I cover workspaces, repos, packages, targets, query commands, and many others. I discuss how Bazel BUILD files work and how to build and run your C++ source files.

Concise and straight to the point. Good job with the reviews in between examples and following all examples.

[@halilibrahimakgun7569]

I think, you explained a complicated topic in a simple way. Thanks.

[@user-nd1jf1rc2g]

thanks a lot for this incredibly helpful tutorial!

[@vivekmaurya571]

This is so informative 😊 thanks!!

[@87yassmin]

Very informative video 👏 Thanks

[@palasghosh182]

Thanks for this informative tutorial. This tutorial can be extended on the topic how to set compiler options and integration of Google test.

[@HuyNguyen-ms3zi]

I would be grateful if you could teach us also advanced features of Bazel. Good tutorial resources for them are very scarce on the internet.

[@gfaerny]

Thanks ari

[@RamsesAldama]

Nice tutorial. How do you choose the compiler and the standard to compile?

[@manikandanraju3673]

Does it compile with gcc compiler? is`nt clang default compiler for bazel C++?

[@Tabbu84]

I am working in one of the bazel python project need your support.
Plz let me know How to contact you

[@user-lc6gm9kn8q]

Why is this not the official "get-started" ?

[@romhoor]

Why do you rush so much?

[@arisaif]

I'm working on pacing myself!

[@ashwinberyl4552]

@romhoor Watch on x0.75 speed

Thank you for the video. I have got the below error and struggling to solve. Could you please help me?

The error message indicates that the bazel build process is failing due to a permission denied issue when trying to execute a CppCompile command. Here are a few steps to troubleshoot and resolve this issue:
Check Permissions:
Ensure that you have the necessary permissions to access the directory and files involved in the build process. You can try running chmod -R 755 /home/vijay/RDK/AI-ML/bazel/yt_tutorial/bazel_tutorial/ to grant read, write, and execute permissions to the user.
Run as Root:
If the permission issue persists, try running the build command as root using sudo. For example, sudo bazel run examples/example1:example1.
Sandbox Debugging:
Use the --sandbox_debug flag to get more detailed information about what is happening in the sandbox environment. This can provide more insights into why the permission is being denied.
