@section building-packages Prepared packages
The easiest way to install Magnum is to use one of the ready-made packages for
your platform of choice. See @ref building-manual if you want to have more
control and @ref building-cross for cross-compiling to other platforms.
- @ref building-packages-arch
- @ref building-packages-deb
- @ref building-packages-gentoo
- @ref building-packages-brew
The engine itself is kept as small as possible with only minimal dependencies.
In order to use extra functionality, often depending on external libraries, you
need to build also packages of additional repositories. Various importer
plugins for image, audio and 3D model formats are maintained in the
@ref building-plugins "Plugins repository", integration with external math and
physics libraries is provided by @ref building-integration "Integration libraries"
and other extra features are in the @ref building-extras "Extra libraries".
Various examples are provided by the @ref building-examples "Example repository".
@subsection building-packages-arch ArchLinux packages
In `package/archlinux/magnum-git` there is a package for Git development build.
The package is also in AUR as
[magnum-git](https://aur.archlinux.org/packages/magnum-git/). It depends on the
@ref building-corrade-packages-arch "Corrade ArchLinux package".
There are also quite a few development packages for native builds, OpenGL ES
builds, cross-compilation for Emscripten, Android and MinGW or various
sanitizer/coverage builds. 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:
@code{.sh}
git clone git://github.com/mosra/magnum && cd magnum
cd package/archlinux
makepkg -fp PKGBUILD # or any other PKGBUILD file
@endcode
In most cases the development PKGBUILDs also contain a @cb{.sh} check() @ce
function which will run all unit tests before packaging. That might sometimes
fail or take too long, pass `--nocheck` to `makepkg` to skip that.
Once built, install the package using `pacman`:
@code{.sh}
sudo pacman -U magnum-*.pkg.tar.xz
@endcode
Edit the PKGBUILDs if you want to pass additional flags to CMake or
@ref building-features "enable / disable additional features".
There are also ArchLinux packages for @ref building-plugins-packages-arch "Magnum Plugins", @ref building-integration-packages-arch "Magnum Integration",
@ref building-extras-packages-arch "Magnum Extras" and
@ref building-examples-packages-arch "Magnum Examples".
@subsection building-packages-deb Packages for Debian, Ubuntu and derivatives
The `package/debian/` directory contains all files needed for building Debian
packages. You need the @ref building-corrade-packages-deb "Corrade Debian package"
installed and in addition also the `dpkg-dev` and `debhelper` packages.
Building is easy, just change directory to package root, link or copy
`package/debian` directory there and run `dpkg-buildpackage`:
@code{.sh}
git clone git://github.com/mosra/magnum && cd magnum
ln -s package/debian .
dpkg-buildpackage
@endcode
This will compile binary and development packages, which will then appear in a
parent directory. Install them using `dpkg`:
@code{.sh}
sudo dpkg -i ../magnum*.deb
@endcode
If you want to pass additional flags to CMake or
@ref building-features "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.
There are also Debian packages for @ref building-plugins-packages-deb "Magnum Plugins", @ref building-integration-packages-deb "Magnum Integration",
@ref building-extras-packages-deb "Magnum Extras" and
@ref building-examples-packages-deb "Magnum Examples".
@subsection building-packages-gentoo Gentoo Linux ebuilds
Gentoo Git ebuild is available in the `package/gentoo` directory. Get the
@ref building-corrade-packages-gentoo "Corrade Gentoo package" first and then
build and install Magnum like this:
@code{.sh}
git clone git://github.com/mosra/magnum && cd magnum
cd package/gentoo
sudo ebuild dev-libs/magnum/magnum-99999.ebuild manifest clean merge
@endcode
If you want to pass additional flags to CMake or
@ref building-features "enable / disable additional features", add them to
`mycmakeargs` in the `*.ebuild` file.
There are also Gentoo packages for @ref building-plugins-packages-gentoo "Magnum Plugins", @ref building-integration-packages-gentoo "Magnum Integration",
@ref building-extras-packages-gentoo "Magnum Extras" and
@ref building-examples-packages-gentoo "Magnum Examples".
@subsection building-packages-brew Homebrew formulas for macOS
macOS [Homebrew](https://brew.sh) 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. When installing from
the `*.rb` files you need to install the
@ref building-corrade-packages-brew "Corrade Homebrew package" first, otherwise
you can do just this:
@code{.sh}
brew install --HEAD mosra/magnum/corrade
brew install --HEAD mosra/magnum/magnum
@endcode
If you want to pass additional flags to CMake or
@ref building-features "enable / disable additional features", edit the `*.rb`
file.
There are also Homebrew packages for @ref building-plugins-packages-brew "Magnum Plugins", @ref building-integration-packages-brew "Magnum Integration",
@ref building-extras-packages-brew "Magnum Extras" and
@ref building-examples-packages-brew "Magnum Examples".
@section building-manual Manual build
Minimal set of tools and libraries required for building is:
- C++ compiler with good C++11 support. Compilers which are tested to have
everything needed are **GCC** >= 4.7, **Clang** >= 3.1 and **MSVC** >= 2015.
On Windows you can also use **MinGW-w64**.
- **CMake** >= 2.8.12
- **Corrade** - Plugin management and utility library. See
- **Corrade** --- Plugin management and utility library. See
@ref building-corrade "Corrade download and installation guide" for more
information.
Note that full feature set is available only on GCC 4.8.1 and Clang 3.1.

The library is constantly evolving and thus some APIs are deprecated and then
later removed in favor of better ones. To preserve backwards compatibility,
Magnum is by default built with all deprecated APIs. However, to make your
code more robust and future-proof, it's recommended to build the library with

enabled by default when `TARGET_GLES` is set.
- `TARGET_DESKTOP_GLES` --- Target OpenGL ES on desktop, i.e. use OpenGL ES
emulation in desktop OpenGL library . Available on Linux and Windows, though
emulation in desktop OpenGL drivers . Available on Linux and Windows, though
might not be supported by all drivers.
- `TARGET_HEADLESS` --- Build command-line utilities for use on a headless
machine. Basically it means that EGL with no display attachment is being
used everywhere instead of platform-specific toolkits like CGL, GLX or WGL.
Supported mainly on OpenGL ES drivers, for desktop OpenGL the only driver
that supports this configuration is NVidia >= 355.

@section building-related Related projects
The engine itself is kept as small as possible with only little dependencies.
Additional functionality, often depending on external libraries, is provided in
separate repositories. Various importer plugins for image, audio and 3D model
formats are maintained in @ref building-plugins "Plugins repository",
integration with various external math and physics libraries is provided by
@ref building-integration "Integration libraries" and other extra features are
in the @ref building-extras "Extra libraries". Various examples are provided
by the @ref building-examples "Examples repository".
@section building-packages Prepared packages
@subsection building-packages-arch ArchLinux packages
In `package/archlinux` directory is currently one package for Git development
build. The package is also in AUR under the same name.
There are also a few development PKGBUILDs in `package/archlinux`, which allow
you to build and install the package directly from source tree without
downloading anything. The native PKGBUILDs also contain @cb{.sh} check() @ce
function which will run all unit tests before packaging.
@subsection building-packages-gentoo Gentoo ebuilds
Gentoo Git ebuild is available in `package/gentoo` directory.
@subsection building-packages-deb DEB packages
There is also `package/debian/` directory with all files needed for building
Debian packages. You need to have `corrade-dev` DEB package installed and in
addition also `dpkg-dev` and `debhelper` packages. Building is easy, just
change directory to package root, link or copy `package/debian` directory there
and run `dpkg-buildpackage`:
@code{.sh}
ln -s package/debian .
dpkg-buildpackage
@endcode
This will compile binary and development packages, which will then appear in
parent directory. If you need to modify CMake flags (enabling/disabling some
features, for example), modify the last entry in `debian/rules`.
@subsection building-packages-brew Homebrew formulas
macOS Homebrew formulas are in `package/homebrew` directory. Either use the
`*.rb` files directly or use the tap at https://github.com/mosra/homebrew-magnum :
@code{.sh}
brew install --HEAD mosra/magnum/magnum
@endcode
in the root directory (i.e. where `Doxyfile` is). The resulting HTML
documentation will be in the `build/doc/` directory. You might need to create
the `build/` directory if it doesn't exist yet. If Corrade with generated
documentation is placed in the `corrade` directory next to `magnum`, the
documentation will be crosslinked with Corrade's one. If related projects
(`magnum-plugins`, `magnum-extras`, `magnum-integration` and `magnum-examples`,
see below) are places along these, their documentation will be also included in
generated output.
The documentation can be also generated using the
[m.css Doxygen theme](http://mcss.mosra.cz/doxygen/). Use `Doxyfile-mcss` for a
local build, the `Doxyfile-public` is meant for the publicly available
documentation at http://doc.magnum.graphics/magnum/. The resulting
documentation will be either in `build/doc-mcss/` or `build/doc-public/`.
