bazel

To write Bazel BUILD files for C++ projects, define your compilation targets using rules like cc_library and cc_binary. This structures source code into reproducible build components within the dependency graph.

Bzlmod manages external dependencies in Bazel by using MODULE files to declare and resolve project requirements. This system replaces legacy WORKSPACE configurations to provide reliable, transitive dependency resolution.

The best way to analyze a Bazel dependency graph is using the bazel query and cquery commands. These tools inspect your project structure, trace target dependencies, and help optimize build execution paths.

Registering a custom C++ toolchain in Bazel involves configuring build constraints and defining toolchain rules. This ensures Bazel selects the correct compilers and linkers for your specific development environment.

Bazel sandbox debugging fails during C++ builds when file permissions restrict access or hidden dependencies bypass the declared build graph. Isolating execution environments requires strict dependency declaration.

Bazel supports remote execution for distributed C++ builds by sending build actions to shared worker pools. This accelerates compilation times and enables remote caching across network infrastructure.
