Dependencies
------------
nsxiv requires the following software to be installed:
* Imlib2
* X11
* Xft
* freetype2
* fontconfig
The following libraries are optional. They are automatically enabled if installed.
* giflib : Used for animated gif playback.
* libexif : Used for auto-orientation and exif thumbnails.
* libwebp : Used for animated webp playback.
Please make sure to install the corresponding development packages in case that
you want to build nsxiv on a distribution with separate runtime and development
packages (e.g. \*-dev on Debian).
Building
--------
nsxiv is built using the commands:
$ make
Running make will automatically detect if libexif and libgif are available and
enable them if so. CLI arguments will override any automatic detection.
For example:
$ make HAVE_LIBGIF=0
will always disable libgif.
Alternatively, they can be disabled via editing `config.mk`.
Installing nsxiv:
# make install
Installing desktop entry:
# make install-desktop
Installing icons:
# make install-icon
Installing all of the above:
# make install-all
Please note, that these requires root privileges.
By default, nsxiv is installed using the prefix `/usr/local`, so the full path
of the executable will be `/usr/local/bin/nsxiv`, the `.desktop` entry will be
`/usr/local/share/applications/nsxiv.desktop` and the icon path will be
`/usr/local/share/icons/hicolor/{size}/apps/nsxiv.png`.
You can install nsxiv into a directory of your choice by changing this command to:
$ make PREFIX="/your/dir" install
Example scripts are installed using `DOCPREFIX` which defaults to
`/usr/local/share/doc/nsxiv`. You can change `DOCPREFIX` the same way you can
change `PREFIX` shown above.
The build-time specific settings of nsxiv can be found in the file *config.h*.
Please check and change them, so that they fit your needs.
If the file *config.h* does not already exist, then you have to create it with
the following command:
$ make config.h
Usage
-----
Please see man page for information on how to use nsxiv. To do so, execute the
following after the installation:
