Ninja is a small build system with a focus on speed. https://ninja-build.org/
See the manual or
doc/manual.asciidoc included in the distribution for background
and more details.
Binaries for Linux, Mac and Windows are available on
GitHub.
Run ./ninja -h for Ninja help.
Installation is not necessary because the only required file is the resulting ninja binary. However, to enable features like Bash completion and Emacs and Vim editing modes, some files in misc/ must be copied to appropriate locations.
If you're interested in making changes to Ninja, read CONTRIBUTING.md first.
You can either build Ninja via the custom generator script written in Python or via CMake. For more details see the wiki.
./configure.py --bootstrap
This will generate the ninja binary and a build.ninja file you can now use
to build Ninja with itself.
cmake -Bbuild-cmake
cmake --build build-cmake
The ninja binary will now be inside the build-cmake directory (you can
choose any other name you like).
To run the unit tests:
./build-cmake/ninja_test
You must have asciidoc and xsltproc in your PATH, then do:
./configure.py
ninja manual doc/manual.pdf
Which will generate doc/manual.html.
To generate the PDF version of the manual, you must have dblatext in your PATH then do:
./configure.py # only if you didn't do it previously.
ninja doc/manual.pdf
Which will generate doc/manual.pdf.
If you have doxygen installed, you can build documentation extracted from C++
declarations and comments to help you navigate the code. Note that Ninja is a standalone
executable, not a library, so there is no public API, all details exposed here are
internal.
./configure.py # if needed
ninja doxygen
Then open doc/doxygen/html/index.html in a browser to look at it.
