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:

$ man nsxiv
