团结建设的好处/缺点？ [英] The benefits / disadvantages of unity builds?

问题描述

从一个新公司开始，我注意到他们使用unity cpp文件为我们的大多数解决方案，我想知道是否有人能够给我一个明确的理由，为什么和如何这些加速构建处理？我会认为在unity文件中编辑一个cpp文件将强制重新编译所有这些文件。

Since starting at a new company I've noticed that they use unity cpp files for the majority of our solution, and I was wondering if anyone is able to give me a definitive reason as to why and how these speed up the build process? I would've thought that editing one cpp file in the unity files will force recompilation of all of them.

推荐答案

和好的答案： #include所有.cpp文件到一个编译单元？

总结似乎是较少的I / O开销是主要的好处。

The summary seems to be that less I/O overhead is the major benefit.
