In the ever-evolving world of software development, ensuring code quality and maintainability is paramount. Two seemingly unrelated concepts, const correctness in C++ and ephemeral build environments from DevOps, share a surprising connection, both aiming to build a strong foundation for reliable software.

Const Correctness: Enforcing Immutability in Code​

Const correctness is a programming paradigm in C++ that emphasizes the use of the const keyword to explicitly declare variables and objects that shouldn't be modified. This enforces a form of immutability within your code. Just like an immutable object in other languages, a const variable cannot have its value changed after initialization.

The ever-evolving world of C++ development unlocks incredible possibilities, but one persistent challenge haunts programmers: dependency management. While libraries often steal the spotlight, the true scope of dependencies extends far beyond. It encompasses the entire toolchain ecosystem, from the compilers and operating systems used to craft your code for the operating systems where it ultimately executes on.

Imagine building a spacecraft. While the engine is undeniably crucial, neglecting the guidance system, navigation tools, and communication equipment would be disastrous. Similarly, focusing solely on libraries paints an incomplete picture. Every software tool you utilize, from the ground up, contributes to the final product's functionality, stability, and maintainability.

This guide delves into the intricate tooling and dependencies, exploring the various categories, offering effective management strategies, and practical examples across diverse project types. By venturing beyond the surface level of libraries, we equip you with the knowledge and tools to navigate the dependency landscape with confidence and efficiency, ensuring your C++ projects reach their full potential.

C++ developers often approach DevOps with a reasonable degree of skepticism, and it's not without reason. Their top five challenges revolve around build scripts, dependency management, and setting up CI pipelines—areas traditionally associated with DevOps responsibilities. Michael Xymitoulias articulated this sentiment well in a recent LinkedIn post writing:

Right now, it feels that C++ developers have to deal with way more than just writing business logic code. [...] Allowing devs to focus more on coding rather than trying to solve problems of the ecosystem would probably be liberating

Xymitoulias suggestion that allowing developers to focus more on coding, rather than grappling with ecosystem problems, would be liberating. He's not alone, Bill Hoffman, CTO behind CMake supports this ideal of simplifying the developer workflows, something we've seen put in place with recent improvements to the popular build system.

While building in C++ certainly comes with its challenges, streamlining this process is our collective goal. So, let's delve into the core focus as it relates to C++ and dispel some common misconceptions.

In the steadily evolving landscape of C++, where incremental improvements shape the tools we use, it can quickly become a challenge to stay up to date with the latest technologies while still supporting the code already in production. If you're apart of the 61% of C++ developers, the concept of building more configurations might initially seem counterintuitive. However, it's precisely under such circumstances that this approach serves as a solution to the challenge of limited access to new features and tools within the C++ ecosystem.

By prioritizing testing a comprehensive list of configuration during CI, your team can unleash access to new features and tools, boosting productivity and ensuring project longevity and compatibility in a competitive landscape by establishing guardrails for the project.

Let's delve deeper into the compelling reasons why this DevOps approach, centered around building more configurations, deserves widespread adoption in C++ environments.

Managing build scripts, especially in C++, can be a daunting task for development teams. CMake, with its powerful toolkit, offers a solution to this challenge. In this blog, we'll delve into the world of CMake presets and explore how they can significantly reduce CI build script complexity, leading to a more efficient and enjoyable development experience.

The Challenge of Build Scripts in C++​

C++ teams often struggle with an extensive list of build systems, introducing layers of complexity. CMake, when mastered, becomes a game-changer. This blog focuses on CMake's key pillars: toolchains, presets, and build scripts. Understanding their roles and interactions is crucial for achieving a streamlined developer experience and unambiguous CI workflows.

Join us on a journey where we'll:

• Empower developers with effortless configuration and cross-platform builds.
• Simplify CI pipelines for efficient testing.
• Elevate project maintainability and collaboration across diverse environments.

One of the biggest challenges in C++ is setting up CI from scratch and of that, the biggest pain point is the system administration which can be very disconnected from the development tools. In order to bridge this gap we can leverage Infrastructure as Code (IaC) targeting existing machines, locally in our network or in the cloud, is an excellent enhancement to ensure consistent reproducible builds. Having version controlled configuration management tied to the codebase is key, this will allow us to deterministically install all the tools required with confidence even in the far far future.

Let's walk through adding Ansible to handle configuring a Windows virtual machine. These ideas apply to Unix environments as well but we can tackle those in a future post. Once we've gained control over our build environments, we can tackle availability and scalability by introducing Terraform to help provision and initialize new Windows instances in Azure. This two prong solution enables both a path for migrating to the cloud and establishing a hybrid setup.

In the ever-evolving landscape of C++ development, challenges abound, but the journey to overcome them has a powerful ally: DevOps. The annual ISO committee's survey paints a vivid picture of the hurdles faced by C++ developers, but within these challenges lie opportunities for transformation through DevOps principles and cutting-edge technologies like Artifact Management, Infrastructure as Code (IaC), and Platforms as a Service (PaaS).

Unveiling the Challenges​

The 2023 ISOCPP Survey echoes the sentiments of C++ developers grappling with key issues:

1. Managing libraries my application depends on: 83%
2. Build times: 81%
3. Setting up a continuous integration pipeline from scratch: 72%
4. Managing CMake projects: 67% (MakeFiles MSBuild)
5. Setting up a development environment from scratch: 67%

In the ever-evolving landscape of software development, the transformative influence of DevOps cannot be overstated. It has reshaped how teams collaborate, develop, build, test, and ultimately deliver applications. DevOps is more than a mere collection of practices or tools; it embodies a cultural shift, fostering collaboration and communication among software developers, QA professionals, and IT operations.

Today, we navigate the intricate landscape of C++, delving into how the DevOps approach aligns seamlessly with both historical and contemporary roles within the ecosystem. It becomes apparent that DevOps best practices hold the key to unlocking solutions for some of the most prevalent challenges faced by C++ developers.
