### Abstract: From Source to Binary: Cross-Compiling in Go Explained
Cross-compiling, the process of building executable binaries for multiple operating systems and architectures from a single source code base, is a critical capability for modern software development. This talk aims to demystify cross-compiling in Go, a language renowned for its simplicity and efficiency.
The session begins with an introduction to cross-compiling, explaining its importance in scenarios such as multi-platform deployment, embedded systems development, and continuous integration pipelines. We'll then dive into Go's powerful cross-compilation features, which enable developers to target different platforms effortlessly.
Attendees will learn about Go's toolchain, particularly the `go build` command, and how environment variables such as `GOOS` and `GOARCH` are used to specify the desired target operating system and architecture. We will explore practical examples of cross-compiling Go applications for various platforms, including Linux, Windows, macOS, and ARM-based systems.
The talk will also address common challenges and best practices in cross-compiling, such as handling platform-specific dependencies, managing external libraries, and optimizing binary size and performance. We will showcase tools and techniques to streamline the cross-compilation process, including the use of Docker for creating reproducible build environments.
By the end of this session, participants will have a comprehensive understanding of how to effectively cross-compile Go programs, enabling them to deliver consistent and reliable binaries across diverse platforms with ease.
