Cross-Platform Go Builds with OS-Specific Files

Building command-line tools and applications that run seamlessly across Windows, macOS, and Linux can be challenging when dealing with platform-specific system calls or file paths. To write elegant cross-platform Go code, you must master how the compiler selects and excludes files for different target environments. This text-only course guides you from the foundational concepts of compilation targets to managing complex, multi-platform codebases. You will learn how to structure your projects so that the Go compiler only includes the code relevant to the target operating system, ensuring clean builds every time. What you'll learn: - Understand the core concepts of cross-compilation and how the Go compiler targets different operating systems and architectures - Apply file naming conventions to automatically target specific operating systems during the build process - Implement custom build tags to control compilation with fine-grained logic and boolean constraints - Structure Go packages to cleanly separate platform-independent logic from OS-specific implementations - Practice modern Go packaging workflows and manage dependencies across diverse platforms - Test platform-specific code paths using standard testing tools to ensure reliable behavior on every target Starting with basic compilation mechanics, this course walks you through real-world scenarios, moving from simple file-naming rules to advanced build constraint logic. It is designed for beginner to intermediate Go developers who want to write portable, professional software without any prior cross-compilation experience.
