Ccache for Windows

Accelerate rebuilds with ccache

ccache is a small, focused tool that speeds up repeated compilations by reusing previous compiler outputs. When a compilation request matches a cached result, ccache returns the stored object file instead of running the compiler again, cutting down rebuild times that would otherwise be spent on unchanged code.

Why developers benefit

Developers working on large codebases or frequently changing source files see the most gain. Typical advantages include:

• noticeably shorter incremental build times, especially during iterative development
• fewer wasted CPU cycles and reduced overall compile load
• a smoother edit-compile-test cycle that increases productivity

Capabilities and platform support

ccache is built to be flexible and broadly useful:

• supports major compiled languages such as C++ and C
• distributed under the GNU GPL version 3 (or later), making it free to use and modify
• works across multiple operating systems, so it integrates into varied development environments

Alternatives and a quick demo suggestion

If you want to evaluate ccache quickly, try this simple comparison:

• Build a small project once with ccache enabled, then make a trivial change and rebuild to observe the speed difference.
• Repeat the same steps without ccache to compare elapsed times and CPU usage.

These quick tests give a practical sense of how much time ccache can save in your workflow and help you decide whether to add it into your regular build process.
