Bazel and Protobuf C++ Example

Dependencies

Follow this to install bazel - https://bazel.build/install Follow this to clone and install the protobuf library - https://github.com/protocolbuffers/protobuf/tree/main/src

Key Files -

1. BUILD file - Contains the build instructions for the target.
2. MODULE.bazel file - Contains the module name and the dependencies.

Building and running with the proto -

This flag is necessary --experimental_google_legacy_api to use the protobuf library.

To build all targets, use the following command -

bazel build //... --experimental_google_legacy_api

To run the target, use the following command -

./bazel-bin/target_name

For granular build control, use the following commands -

bazel build //target_directory:target_name --experimental_google_legacy_api

How to build and run with Bazel in general -

Build using bazel build command -

1. If in target directory and only one target is there, then use bazel build
2. If in target directory and multiple targets are there, then use bazel build //target_name
3. If outside target directory, then use bazel build //target_directory:target_name

Execute using ./bazel-bin/target_name command.

To clean the build files -

bazel clean
