External Libraries
@ -191,7 +194,141 @@ Many of Pillow's features require external libraries:
* **libxcb** provides X11 screengrab support.
Once you have installed the prerequisites, run::
.. tab:: Linux
If you didn't build Python from source, make sure you have Python's
development libraries installed.
In Debian or Ubuntu::
sudo apt-get install python3-dev python3-setuptools
In Fedora, the command is::
sudo dnf install python3-devel redhat-rpm-config
In Alpine, the command is::
sudo apk add python3-dev py3-setuptools
.. Note:: ``redhat-rpm-config`` is required on Fedora 23, but not earlier versions.
Prerequisites for **Ubuntu 16.04 LTS - 22.04 LTS** are installed with::
sudo apt-get install libtiff5-dev libjpeg8-dev libopenjp2-7-dev zlib1g-dev \
libfreetype6-dev liblcms2-dev libwebp-dev tcl8.6-dev tk8.6-dev python3-tk \
libharfbuzz-dev libfribidi-dev libxcb1-dev
To install libraqm, ``sudo apt-get install meson`` and then see
``depends/install_raqm.sh``.
Prerequisites are installed on recent **Red Hat**, **CentOS** or **Fedora** with::
sudo dnf install libtiff-devel libjpeg-devel openjpeg2-devel zlib-devel \
freetype-devel lcms2-devel libwebp-devel tcl-devel tk-devel \
harfbuzz-devel fribidi-devel libraqm-devel libimagequant-devel libxcb-devel
Note that the package manager may be yum or DNF, depending on the
exact distribution.
Prerequisites are installed for **Alpine** with::
sudo apk add tiff-dev jpeg-dev openjpeg-dev zlib-dev freetype-dev lcms2-dev \
libwebp-dev tcl-dev tk-dev harfbuzz-dev fribidi-dev libimagequant-dev \
libxcb-dev libpng-dev
See also the ``Dockerfile``\s in the Test Infrastructure repo
(https://github.com/python-pillow/docker-images) for a known working
install process for other tested distros.
.. tab:: macOS
The Xcode command line tools are required to compile portions of
Pillow. The tools are installed by running ``xcode-select --install``
from the command line. The command line tools are required even if you
have the full Xcode package installed. It may be necessary to run
``sudo xcodebuild -license`` to accept the license prior to using the
tools.
The easiest way to install external libraries is via `Homebrew
<https://brew.sh/>`_. After you install Homebrew, run::
brew install libjpeg libtiff little-cms2 openjpeg webp
To install libraqm on macOS use Homebrew to install its dependencies::
brew install freetype harfbuzz fribidi
Then see ``depends/install_raqm_cmake.sh`` to install libraqm.
.. tab:: Windows
We recommend you use prebuilt wheels from PyPI.
If you wish to compile Pillow manually, you can use the build scripts
in the ``winbuild`` directory used for CI testing and development.
These scripts require Visual Studio 2017 or newer and NASM.
The scripts also install Pillow from the local copy of the source code, so the
`Installing`_ instructions will not be necessary afterwards.
.. tab:: Windows using MSYS2/MinGW
To build Pillow using MSYS2, make sure you run the **MSYS2 MinGW 32-bit** or
**MSYS2 MinGW 64-bit** console, *not* **MSYS2** directly.
The following instructions target the 64-bit build, for 32-bit

.. tab:: FreeBSD
.. Note:: Only FreeBSD 10 and 11 tested
Make sure you have Python's development libraries installed::
sudo pkg install python3
Prerequisites are installed on **FreeBSD 10 or 11** with::
sudo pkg install jpeg-turbo tiff webp lcms2 freetype2 openjpeg harfbuzz fribidi libxcb
Then see ``depends/install_raqm_cmake.sh`` to install libraqm.
.. tab:: Android
Basic Android support has been added for compilation within the Termux
environment. The dependencies can be installed by::
pkg install -y python ndk-sysroot clang make \
libjpeg-turbo
This has been tested within the Termux app on ChromeOS, on x86.
