ArchLinux packages

In package/archlinux/magnum-examples-git there is a package for Git development build. The package is also in AUR as The package is also in AUR as magnum-examples-git. It depends on Corrade, Magnum, Magnum Plugins, Magnum Extras and Magnum Integration ArchLinux packages.

There are also quite a few development packages for native builds or cross-compilation for Emscripten, Android and MinGW. See the PKGBUILD files in the package/archlinux directory. They allow you to build and install the package directly from the source tree. Example usage:

git clone https://github.com/mosra/magnum-examples && cd magnum-examples
cd package/archlinux
makepkg -fp PKGBUILD # or any other PKGBUILD file

Once built, install the package using pacman:

sudo pacman -U magnum-examples-*.pkg.tar.zst

Edit the PKGBUILDs if you want to pass additional flags to CMake or enable / disable additional features.

Packages for Debian, Ubuntu and derivatives

The package/debian/ directory contains all files needed for building Debian packages. You need Corrade, Magnum, Magnum Plugins, Magnum Extras and Magnum Integration Debian packages installed and in addition also the dpkg-dev and debhelper packages. Building is easy, just change directory to package root, link or copy the package/debian directory there and run dpkg-buildpackage:

git clone https://github.com/mosra/magnum-examples && cd magnum-examples
ln -s package/debian .
dpkg-buildpackage --no-sign

This will compile binary and development packages, which will then appear in a parent directory. Install them using dpkg:

sudo dpkg -i ../magnum-examples*.deb

If you want to pass additional flags to CMake or enable / disable additional features, add them to dh_auto_configure at the bottom of debian/rules. Watch out, as indentation has to be done using tabs, not spaces.

Gentoo Linux ebuilds

Gentoo Git ebuild is available in the package/gentoo directory. Get the Corrade, Magnum, Magnum Plugins, Magnum Extras and Magnum Integration Gentoo packages first and then build and install Magnum Examples like this:

git clone https://github.com/mosra/magnum-examples && cd magnum-examples
cd package/gentoo
sudo ebuild dev-libs/magnum-examples/magnum-examples-9999.ebuild manifest clean merge

If you want to pass additional flags to CMake or enable / disable additional features, add them to mycmakeargs in the *.ebuild file.

Packages for Fedora, openSUSE and other RPM-based Linux distributions

Spec files for RPM-based distributions are in the package/rpm/ directory. In addition you will need to install the following dependencies in order to build the packages (assuming Fedora Linux):

sudo dnf install fedora-packager rpmdevtools

After that, make sure you build and install the Corrade, Magnum, Magnum Plugins, Magnum Extras and Magnum Integration RPM packages first, and run the build.sh script. Internally it queries the Git version, makes a tarball, may ask you to install appropriate dependencies if not present already, and then builds the package.

./package/rpm/build.sh

At the end, if everything succeeds, you'll have the newly built packages located in ~/rpmbuild/RPMS. The script will print their names at the end.

If you want to pass additional flags to CMake or enable / disable additional features, edit the *.spec file.

Homebrew formulas for macOS

macOS Homebrew formulas building the latest Git revision are in the package/homebrew directory. Either use the *.rb files directly or use the tap at https://github.com/mosra/homebrew-magnum. This will install the latest stable version of Magnum Examples with all dependencies:

brew install mosra/magnum/magnum-examples

But often you may want to install the latest Git revision of all Magnum projects instead:

brew install --HEAD mosra/magnum/corrade
brew install --HEAD mosra/magnum/magnum
brew install --HEAD mosra/magnum/magnum-plugins
brew install --HEAD mosra/magnum/magnum-integration
brew install --HEAD mosra/magnum/magnum-extras
brew install --HEAD mosra/magnum/magnum-examples

# If already installed, use the following to upgrade, in the same order
brew upgrade --fetch-HEAD mosra/magnum/corrade
brew upgrade --fetch-HEAD mosra/magnum/magnum
brew upgrade --fetch-HEAD mosra/magnum/magnum-plugins
brew upgrade --fetch-HEAD mosra/magnum/magnum-integration
brew upgrade --fetch-HEAD mosra/magnum/magnum-extras
brew upgrade --fetch-HEAD mosra/magnum/magnum-examples

When installing from the *.rb files you need to install the Corrade, Magnum, Magnum Plugins, Magnum Extras and Magnum Integration Homebrew packages first. If you want to pass additional flags to CMake or enable / disable additional features, edit the *.rb file.

Enabling or disabling features

By default only the Triangle example is built. All examples depend on various libraries from the core Magnum repository and the Platform::Sdl2Application class, unless said otherwise.

Some examples accept additional options:

• MAGNUM_FLUIDSIMULATION3D_EXAMPLE_USE_TBB — If enabled together with MAGNUM_FLUIDSIMULATION3D_EXAMPLE_USE_MULTITHREADING, uses Intel TBB for parallel processing in the 3D Fluid Simulation example. OFF by default.

Besides building the whole project and enabling a particular subset of examples, it's also possible to build each example as if the example itself would be a project root. For example:

cd magnum-examples
mkdir build-cubemap && cd build-cubemap
cmake ../src/cubemap
# ...
