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.

[halilibrahimakgun]

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

[RajBhalekar-lz]

your explanation skill is awesome and simple.. Thanks for this video ... If possible please upload other part of bazel videos also

[王江奎]

thanks a lot for this incredibly helpful tutorial!

[palasghosh]

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

[HuyNguyen-mszi]

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.

[itsmanikandanraju]

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

[RamsesAldama]

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

[ChethanP-gj]

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

[Tabbu]

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