Explore techniques to significantly reduce C++ build times in this comprehensive conference talk from code::dive 2018. Delve into the reasons behind long compilation and linking times in C++, and discover an extensive array of tools and methods to address this productivity-hindering issue. Learn about parallel builds, meta build systems, linking strategies, compiler caches, distributed builds, and hardware optimizations. Gain insights into the PIMPL idiom, effective template usage, and code annotations. Understand the concept of C++ modules, their history, motivation, and implementation, as well as their impact on obsolete techniques. Acquire practical knowledge to enhance your C++ development workflow and boost productivity through faster build times.
