history

Project history and usage

Clang Build Analyzer is a C and C++ build analysis tool that aggregates Clang -ftime-trace JSON files and reports where compilation time is spent. It is a package-nerd tool for people optimizing slow native builds rather than a general application framework.

Project history

The repository was created in August 2019 after Clang 9 introduced -ftime-trace. The README says the tool takes the single-file trace output generated by Clang and aggregates many compilation traces into summaries of slow files, templates, functions, code generation, and expensive headers.

Adoption history

The supplied package-manager data lists Homebrew and Nix packaging. Release metadata shows an initial 1.0.0 release labeled 'Initial release' and later releases tracking newer Clang support, including Clang 19 support in 1.6.0.

How it is used

A typical workflow starts capture with ClangBuildAnalyzer --start, builds with Clang 9 or later using -ftime-trace, stops capture with --stop, and runs --analyze on the produced capture file. A ClangBuildAnalyzer.ini file in the working directory controls how many expensive files, templates, functions, and headers are reported.

Why package nerds care

It matters because it packages a practical workflow around a compiler diagnostic format. For large C++ codebases, it turns a pile of per-object JSON traces into actionable package-maintainer and build-engineer questions: which headers, templates, source files, or compiler phases are costing rebuild time?

Timeline

2019: Repository created after Clang 9 documented -ftime-trace.
2020: v1.0.0 initial release published on GitHub.
2020: v1.2.0 focused on optimizations for large builds.
2023: v1.5.0 improved expensive-header information.
2025: v1.6.0 added Clang 19 support and fixes.
