Dependencies

Fastfetch dynamically loads needed libraries if they are available. On Linux, its only hard dependencies are libc (any implementation of the c standard library), libdl, libm and libpthread (if built with multithreading support). They are all shipped with glibc, which is already installed on most Linux distributions.

The following libraries are used if present at runtime:

Linux and FreeBSD

• libvulkan: Vulkan module & fallback for GPU output.
• libxcb-randr, libXrandr, libxcb, libX11: At least one of them sould be present in X11 sessions for better display detection and faster WM detection. The *randr ones provide multi monitor support The libxcb* ones usually have better performance.
• libwayland-client: Better display performance and output in wayland sessions. Supports different refresh rates per monitor.
• libdrm: fall back if both wayland and x11 are not available.
• libGIO: Needed for values that are only stored GSettings.
• libDConf: Needed for values that are only stored in DConf + Fallback for GSettings.
• libmagickcore (ImageMagick): Images in terminal using sixel or kitty graphics protocol.
• libchafa: Image output as ascii art.
• libZ: Faster image output when using kitty graphics protocol.
• libDBus: Bluetooth, Player & Media detection.
• libEGL, libGLX, libOSMesa: At least one of them is needed by the OpenGL module for gl context creation.
• libOpenCL: OpenCL module
• libXFConf: Needed for XFWM theme and XFCE Terminal font.
• libsqlite3: Needed for pkg & rpm package count.

Linux only

• librpm: Slower fallback for rpm package count. Needed on openSUSE.
• libnm: Used for Wifi detection.
• libpulse: Used for Sound device detection.
• libddcutil: Used for brightness detection of external displays
• DirectX-Headers: Used for GPU detection in WSL

FreeBSD only

• v4l_compat: Used for camera devices detection. See the official document for detail

macOS

• MediaRemote: Need for Media detection. It's a private framework provided by newer macOS system.
• DisplayServices: Need for screen brightness detection. It's a private framework provided by newer macOS system.
• Apple80211: Need for Wifi detection on Sonoma (and maybe later). It's a private framework provided by newer macOS system.
• MoltenVK: Vulkan driver for macOS. molten-vk
• libmagickcore (ImageMagick): Images in terminal using sixel graphics protocol. imagemagick
• libchafa: Image output as ascii art. chafa
• libsqlite3: Used for fast wallpaper detection before macOS Sonoma ( fallback to AppleScript )

For the image logo, iTerm with iterm image protocol should work. Apple Terminal is not supported.

Windows

• wlanapi: A system dll which isn't supported by Windows Server by default. Used for Wifi info detection.
• libvulkan: Vulkan module. Usually has been provided by GPU drivers. vulkan-loader vulkan-headers
• libOpenCL: OpenCL module. opencl-icd

Note: In Windows 7, 8 and 8.1, ConEmu is required to run fastfetch due to the lack of ASCII escape code native support. In addition, as fastfetch for Windows targets UCRT C runtime library, it must be installed manually as UCRT is only pre-installed in Windows 10 and later.

For the image logo, WezTerm with iterm image protocol is known to work, surprisingly.

Android

• freetype: Used for Termux font detection. freetype
• libvulkan: Vulkan module, also used for GPU detection. Usually has been provided by Android system. vulkan-loader-android vulkan-headers
• termux-api: Used for Wifi / Battery detection. Both the package termux-api and the Android app Termux API must be installed and the app Termux API must be configured to be able to self-running. In order to make Wifi detection actuall work, location privilege must be granted to the app Termux API. Read the official doc for detail.
• libandroid-wordexp-static: wordexp.h support for Android.

For the image logo, Termux Monet supports iterm image protocol.
