In the DevOps playground of software development, designing and maintaining a native build automation process for a complex product over many years presents unique challenges. One topic which often gets over looked by product planning is upgrading compilers. The gritty work for ensuring the product maintains supported for existing platforms while offering access to new tools to developers to be innovative for a competitive edge.

Planning for this change is Toolchain Evolution.

Either maintaining old toolchains as new platforms arrive or a backport of toolchain on to an older platforms or any combination would satisfy the definitions.

There are two main forces driving teams to upgrade their toolchains, the first being security and the second also being security. The first is product security or "code safety", every year compilers and sanitizers are improving and offer new features that when utilized can detect buffer-overflow or free-after-use and prevent many vulnerabilities which are discovered. The second, less talked about, is corporate IT Security or "software supply chain security" where with native toolchains might be obsolete and pose a greater burden to maintain development.

Regardless which of these factors is motivating you, this post will explore the strategic considerations and operational challenges of managing a native build system for long-term success leveraging the concept of Toolchain Evolution during a product's lifecycle to help address both security needs.

The software development landscape is a nebulous. On one front, developers strive to craft innovative features at breakneck speed before requirements change. On another, security threats loom, constantly evolving to exploit vulnerabilities. In this environment, a robust and secure build process is no longer a luxury, it's a necessity as software supply chain attacks become more sophisticated.

This guide introduces the high-level designing a native C or C++ build process that prioritizes both speed and security.

Distributing the Build Work​

Imagine a factory with multiple assembly lines, each focused on a specific part of the product. This parallel approach increases efficiency and speeds up production. Similarly, in a build process, distributing work of various modules across multiple machines creates parallel build pipelines, leading to faster builds and improved scalability. This can be achieved through various means:

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.
