XEphem Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies XEphem-4.1.0.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

Installing XEphem

There are XEphem packages available for several operating systems:

Or you can try compiling from source code. XEphem should compile fine on modern Linux systems, though perhaps not as well for folks on macOS. The source includes an INSTALL file with instructions. There are two ways to get the source:

If you want to get it running quickly from the source code, the repository includes the code for three Docker containers that are each capable of compiling and running XEphem. The commands to launch them when sitting at the repository root are:

$ ./Containers/docker-ubuntu-14.04/run
$ ./Containers/docker-ubuntu-20.04/run
$ ./Containers/docker-ubuntu-21.04/run

Once one of the containers has launched, use the shell command history: press up-arrow to ask for the previous command — it will be the correct command to compile and run XEphem.

The repository also includes a .tito directory and xephem.spec file for building an XEphem RPM package.
