Project description

Mama Build Tool

Mama - A modular C++ build tool even your mama can use

The main goal of this project is to provide extremely convenient in-source builds for cross platform projects. Building is as simple as mama build windows - no ceremony~!

CMake projects with trivial configurations and no dependencies can be handled automatically by Mama. This makes header-only libraries or stand-alone C libraries extremely easy to link.

Adding projects with already configured is trivial and allows you to manage large scale projects in a modular way. Dependencies are added and configured through mamafiles.

Each mama build target exports CMake ${ProjectName}_INCLUDES and ${ProjectName}_LIBS. All exports are gathered in correct linker order inside MAMA_INCLUDES and MAMA_LIBS. This ensures the least amount of friction for developers - everything just works.

There is no central package repository, all packages are pulled and updated from public or private git repositories. Package versioning is done through git tags or branches.

Custom build systems are also supported. For additional documentation explore:

Who is this FOR?

Anyone who develops cross-platform C++ libraries or applications which target any combination of [Windows, Linux, macOS, iOS, Android, Raspberry, Oclea]. And anyone who is not satisfied with system-wide dependencies and linker bugs caused by incompatible system-wide libraries on Linux.

If you require an easy to use, reproducible project/namespace scoped package+build system, this is for you. Your builds will not rely on hard to setup system packages, all you need to do is type mama build.

Supported platforms

  • Windows (64-bit x86_64, 32-bit x86, 64-bit arm64, 32-bit armv7)
  • Linux (Ubuntu) (64-bit x86_64, 32-bit x86)
  • MacOS (64-bit x86_64, 64-bit arm64)
  • iOS (64-bit arm64)
  • Android (64-bit arm64, 32-bit armv7)
  • Raspberry (32-bit armv7)
  • Oclea (64-bit arm64)

Who is this NOT for?

Single platform projects with platform specific build configuration and system wide dependency management such as Linux exclusive G++ projects using apt-get libraries or iOS-only apps using cocoapods.


Provides a mechanism to upload pre-built packages to a private artifactory server through mama upload mypackage. These packages will be automatically used if a git:package commit hash matches.

Setup For Users

  1. Get python 3.6 and PIP
  2. $ pip install mama --upgrade
  3. $ cd yourproject
  4. $ mama init which creates a and patches your CMakeLists.txt
  5. (optional) Manual setup: Create your own (examples below) and add this to your CMakeLists.txt:
target_link_libraries(YourProject PRIVATE ${MAMA_LIBS})
  1. $ mama build and enjoy!
  2. $ mama open to open your project in an IDE / VSCode

Call mama help for more usage information.

Mamafile examples

Project AlphaGL/

import mama
class AlphaGL(mama.BuildTarget):
    # where to build intermediates
    workspace = 'build' # for system-wide workspace, use: global_workspace = 'mycompany'

    # grab dependencies straight from git repositories
    # if the projects are trivial, then no extra configuration is needed
    def dependencies(self):
        # set artifactory package server for prebuilt packages
        # the credentials can be configured by env vars for CI, call `mama help`
        self.set_artifactory_ftp('', auth='store')
        # add packages
        self.add_git('ReCpp',   '', branch='master')
        self.add_git('libpng',  '')
        self.add_git('libjpeg', '')
        self.add_git('glfw',    '')

        # add local packages from existing directory root:
        self.add_local('utils', 'libs/utils')

        # add a prebuilt package, use `mama upload myproject` to generate these:
        self.add_artifactory_pkg('opencv', version='df76b66')
        if self.linux: # or do it conditionally for linux only:
            self.add_artifactory_pkg('opencv', fullname='opencv-linux-x64-release-df76b66')

    # optional: customize package exports if repository doesn't have `include` or `src`
    def package(self):
        self.export_libs('.', ['.lib', '.a']) # export any .lib or .a from build folder
        self.export_includes(['AGL']) # export AGL as include from source folder
        # platform specific system library exports:
        if self.ios:   self.export_syslib('-framework OpenGLES')
        if self.macos: self.export_syslib('-framework OpenGL')
        if self.linux: self.export_syslib('GL')

    def test(self, args):
        self.gdb(f'bin/AlphaGLTests {args}')

If a dependency is non-trivial (it has dependencies and configuration), you can simply place a target mamafile at: mama/{DependencyName}.py

Example dependency config AlphaGL/mama/

import mama
class libpng_static(mama.BuildTarget):
    def dependencies(self):
        # custom mamafile can be passed explicitly:
        self.add_git('zlib', '', mamafile='')

    def configure(self):
        zinclude, zlibrary = self.get_target_products('zlib')
        self.add_cmake_options('BUILD_SHARED_LIB=NO', 'PNG_TESTS=NO')

    def package(self):
        # libpng builds its stuff into `{build}/lib`
        self.export_libs('lib', ['.lib', '.a'])
        # export installed include path from build dir
        self.export_include('include', build_dir=True)

For Mama Contributors

We are open for any improvements and feedback via pull requests.

The package setuptools>=65.0 is required, ensure the version is correct with pip3 show setuptools.

You can set up local development with $ pip3 install -e . --no-cache-dir but make sure you have latest setuptools (>65.0) and latest pip3 (>22.3). This command will fail with older toolkits.

Uploading a source distributionP:

  1. Get dependencies: pip3 install build twine
  2. Build sdist: python -m build
  3. Upload with twine: twine upload dist/* It will prompt for Username and Password, unless you set up ~/.pypirc file:
index-servers = pypi

Quick build & upload using Python 3.9: ./
