mirbuild is the build system used for almost all projects in Last.fm's MIR team. It makes it extremely easy to build, test, install and package

• C++ libraries and services,
• Thrift interfaces and
• Python libraries.

It takes care of

• handling dependencies between projects,
• doing debug, release and code-coverage builds,
• running code coverage tools and
• creating debian packages.

mirbuild is written in Python and needs the setuptools, dateutil, debian and pytest libraries. It also needs cmake for building C++ projects and for running the test suite.

You can build and test mirbuild with

./build.py test

and install it using:

sudo ./build.py install

Have a look at mirbuild/init.py for some usage examples. There's no need to install mirbuild to be able to use it,

export PYTHONPATH=/path/to/python-mirbuild

is sufficient.

It helps to stick to a certain structure when building projects with dependencies. Ideally, all projects are either in the same directory or at least below a certain common directory. To automatically build a project and its dependencies, you can run:

python -m mirbuild.walk -p project build

To build a single project when you know that all dependencies are up-to-date and in the directory above, run:

./build.py --with-deps=.. build
