• #feh on irc.oftc.net

• Imlib2
• libcurl (disable with make curl=0)
• libpng
• libX11
• libXinerama (disable with make xinerama=0)

If built with exif=1:

• libexif-dev
• libexif12

• jpegtran (supplied by the jpeg library, for lossless image rotation)
• convert (supplied by ImageMagick, can be used to load unsupported formats)

For end users:

$ make
$ sudo make install app=1

For package maintainers and users who do not want feh to install its icons into /usr/share:

$ make
$ sudo make install

Explanation: feh ships some icons and an X11 desktop entry, which allow it to be used from file managers, desktop menus and similar. However, installing icons to /usr/local/share/... does not seem to work reliable in all cases. Because of this, when using "make install app=1", feh will install its icons to /usr/share/..., even though they technically belong into /usr/local.

ZSH Completion for feh is available here

Flags can be used to control the build and installation process.

e.g.

make flag=bool

make install flag=bool

or

export flag=bool
make && make install

For example, make xinerama=0 debug=1 will disable Xinerama support and produce a debug build.

Available flags are:

So, by default libcurl and Xinerama are enabled, the rest is disabled.

Additionally, the standard variables PREFIX and DESTDIR are supported.

PREFIX (default: /usr) controls where the application and its data files will be installed. It must be set both during make and make install.

DESTDIR (default: empty) sets the installation root during "make install". It is mostly useful for package maintainers.

Note: config.mk is designed so that in most cases, you can set environment variables instead of editing it. E.g.:

CFLAGS='-g -Os' make

export DESTDIR=/tmp/feh PREFIX=/usr
make && make install

Builtin EXIF support is maintained by Dennis Real, here.

$ make test

Requires perl >= 5.10 with Test::Command. The tests are non-interactive and work without X, so they can safely be run even on a headless buildserver.

Requires

• import (usually supplied by imagemagick)
• perl >= 5.10 with GD, Test::More and X11::GUITest
• twm
• Xephyr

$ make test-x11

Be aware that this is quite experimental, so far the X-tests have only been run on one machine. So they may or may not work for you.
