Bazel features and specs

  • High Scalability
    Bazel is designed to handle large codebases and complex dependency graphs efficiently, which makes it suitable for projects with millions of lines of code.
  • Incremental Builds
    Bazel supports incremental builds by only rebuilding parts of the project that have changed, thus saving time and computational resources.
  • Cross-Platform Support
    Bazel supports different platforms including Linux, MacOS, and Windows, enabling consistent build processes across diverse development environments.
  • Reproducible Builds
    It ensures that the same source code will yield identical build outputs, which is beneficial for debugging and ensuring consistency across different environments.
  • Extensibility
    Bazel is highly extensible, allowing developers to define custom build rules and macros to fit their specific needs.
  • Wide Language Support
    Out of the box, Bazel supports many programming languages such as Java, C++, Python, and Go, with the ability to extend to other languages.

Possible disadvantages of Bazel

  • Steep Learning Curve
    Bazel has a complex configuration language and many internal concepts, which might be challenging for new users to learn and adopt quickly.
  • Limited IDE Integration
    Compared to other build systems, Bazel might have limited or less mature support in certain Integrated Development Environments (IDEs), potentially hindering productivity.
  • Overhead of Remote Caching
    While remote caching is a powerful feature, setting it up and maintaining it can introduce additional overhead and complexity to the build process.
  • Initial Setup Complexity
    Getting a project up and running with Bazel can require significant upfront configuration, especially for projects migrating from another build system.
  • Limited Community Support
    Compared to more established build systems, Bazel has a smaller community, which might result in fewer resources and shared knowledge available online.

CMake features and specs

  • Cross-platform support
    CMake is designed to support multiple operating systems including Windows, macOS, and Linux. This allows developers to write platform-independent CMake scripts.
  • Build tool agnostic
    CMake can generate build files for a variety of build systems including Makefiles, Ninja, and Visual Studio solutions. This means developers are not tied to a specific build tool.
  • Large community and extensive documentation
    CMake has a large user base and an extensive amount of documentation and tutorials available which can be helpful for new and experienced users alike.
  • Integrated testing support
    CMake includes support for testing frameworks such as CTest, which allows for automated testing of code during the build process.
  • Modular and scalable
    CMake is highly modular, enabling users to create reusable and maintainable code by organizing CMake scripts into libraries and modules.

Possible disadvantages of CMake

  • Steep learning curve
    CMake's complexity and its extensive range of features can be difficult for beginners to grasp, leading to a steep learning curve.
  • Verbose syntax
    CMake scripts can often become verbose and difficult to read, especially for large projects. This can make maintenance and debugging challenging.
  • Inconsistent module quality
    The quality and support of different CMake modules can vary, sometimes leading to issues with compatibility or functionality.
  • Performance overhead
    CMake may introduce some performance overhead during the configuration process, especially for very large projects.
  • Complexity in advanced features
    Some of the more advanced features of CMake, such as custom commands and complex dependency management, can be quite difficult to implement correctly.

Analysis of Bazel

Overall verdict

  • Bazel is a powerful and robust build tool, especially for large-scale projects and organizations that require high build performance and scalability. Its advanced features can significantly improve the efficiency of development workflows. However, there is a learning curve, and the complexity of rules and configurations may not suit smaller projects or those with simpler build requirements.

Why this product is good

  • Bazel is a build tool developed by Google that is designed to support fast and correct builds. It is particularly known for its ability to handle large codebases and complex build dependencies efficiently. Bazel uses a single build language across different platforms, and its build system provides features such as incremental builds, remote build execution, and caching, which make it highly suitable for repetitive and reproducible builds. The tool is capable of handling projects written in multiple languages, such as Java, C++, Python, and more, due to its extensibility with custom rules.

Recommended for

  • Large-scale and complex software projects
  • Organizations that utilize monorepos
  • Developers needing cross-platform support
  • Teams looking to leverage remote build execution
  • Projects with complex dependencies across multiple programming languages

Analysis of CMake

Overall verdict

  • CMake is generally considered a good tool for managing the build process of software projects, especially those with a complex codebase that spans multiple platforms.

Why this product is good

  • Flexibility
    It offers great flexibility in terms of defining build processes, enabling advanced configuration and optimization techniques to be used.
  • Integration
    It integrates well with many popular IDEs and other tools, providing a smoother development experience.
  • Wide adoption
    CMake is widely used in the industry, which leads to robust community support and regular updates.
  • Cross platform support
    CMake is designed to support multiple platforms, which makes it highly valuable for projects that need to be compiled and run on different operating systems.

Recommended for

  • projects requiring cross-platform compatibility
  • developers looking for a powerful build configuration tool
  • complex software projects with numerous dependencies
  • teams that value strong community and industry support

  • Why Is This Site Built with C
    Agree regarding easiness of building rust (`cargo build`), extremely satisfying (git clone and cargo build...) Does anyone have any comments on Bazel[1] because I'm kind of settling on using it whenever it's appropriate (c/c++)?.. [1] https://bazel.build/. - Source: Hacker News / 6 months ago
  • 7 Ways to Use the SLSA Framework to Secure the SDLC
    To achieve reproducibility, your build process must control for environmental differences like timestamps, file ordering, or machine-specific configurations. Tools like Bazel or Nixprovide deterministic build systems that lock down these variables. For instance, Bazel uses a content-addressable cache, meaning the same source code and dependencies always result in the same build outputs, even when run on different... - Source: dev.to / 11 months ago
  • Contributing To Open Source - C++ Edition
    Despite following all the steps (on both Windows and Unix), I couldn't get the cmake build to succeed. After several hours of debugging, I decided to try another build method provided by the project, using bazel, which was much simpler. - Source: dev.to / 12 months ago
  • How to effectively work in big codebases
    Many big companies have built their own tools to reign in this complexity and make it easier and faster for developers to work on large, multi-language code bases. Meta has buck, Amazon has brazil, and Google has bazel. But from my experience, especially, with brazil, these tools also have some rough edges, so understanding how they work can go a long way. - Source: dev.to / about 1 year ago
